Accurate industrial thermocouple measurement

Incorporates the Fluke patented Universal Input Connector to bring more accuracy to thermocouple measurements than most other instruments in its class. The Universal Input Connector supports 14 common thermocouple types. Temperature-focused menu selections make the 2638A especially suitable for temperature validation applications. If you need to zero a large number of thermocouples to a known reference temperature before starting a temperature profiling or validation test, this data acquisition system will normalize all readings to your reference channel at the push of a button and store the offsets for reference in a supporting data file. If you are conducting chamber tests, heat treating tests under AMS guidelines, or validating temperature devices under 21 CFR regulations.

Universal input connector

The universal input connector plugs into any open slot in this unit that contains a relay card. The universal input connector has 22 input channels (20 universal inputs and 2 dedicated, lowburden input current channels). Each input connector contains a CJC (cold-junction compensation) device, which is calibrated at the factory. The calibration date and input connector serial number are programmed into the input connector and are read by this instrument when installed. This information is saved in the test setup data file, which is available for review with any associated scan data from a test setup. This feature is a valuable form of traceability if you are working in a regulated industry.

Wiring a test or system setup for 20 to 60 or more channels can be time consuming. With the inexpensive plug-in Universal Input Connector, you can wire your system once, quickly disconnect the connector from your Hydra, then reconnect the Hydra to another input connector for use in a different area.

Other data loggers require you to wire your inputs directly to an expensive “plug-in” active component signal conditioning module. If you need your instrument for another test at another location, you must remove your wiring or use another expensive plug-in signal conditioning module. With this product, all your signal conditioning is inside the mainframe, not in your input connector.

Using multiple low-cost Universal Input Connectors gives you the flexibility to leave your input connector at the test site, completely wired, and ready to use. When you need data from that site, simply plug in and load your saved setup file. It's that simple!

Expandable channel capacity

Comes with three slots in the rear panel. Each slot can hold a user accessible relay card and a 22-channel Universal Input Connector.

Three configurations are available, from 22 channels to 66 channels per mainframe. Select a base model with 22 channels and add 22-channel expansion kits when needed.

Graphical color display with easy-to-use menus

Never get lost again in a complex menu tree while configuring channels or setting up a test. The large, full color, thin film diode (TFD) display enables this unit to display comprehensive easy-tounderstand data and easy menu navigation.

Back-lighted function keys quickly confirm the active menu selection. The “Record” key illuminates to indicate when the 2638A is recording data in scan, monitor or DMM mode. You always have visible confirmation when your data is being recorded.

Copy-and-paste channel functions make repetitive channel setups a simple task. Top-of-screen menu bar headings always let you know where you are in the setup process.

View your data with the push of a button. Page through all channel data and alarms in a quick view mode or scroll through channels and channel statistics individually. Statistics include rate of change, min, max, standard deviation, average, sample size and peak-to-peak information.

Real-time data charting with historical review

Chart the real-time data of up to four channels at once. Simply select your channels and view real time charts of your measurements. The chart will auto scale for best fit of the displayed values. Zoom in or out to view areas of interest with the push of a button. A history mode enables you to scroll through previously collected data within the scan file—all without a PC and expensive charting programs.

Language support

All displayed text in the menus and data display area are translated to eight languages. You can change the language under the instrument setup area with the push of a button. French, Spanish, Japanese, German, Korean, English, Portuguese, Chinese and Russian are all supported languages in this product.

Screen capture function

With one key push on the front panel, you can capture the screen contents of directly to the USB drive in .jpg file format. Capture trend chart results or data displays for reports or just closer review.

Two alarms per channel

Each channel can be set for two alarm points: High-High, High-Low or Low-Low, in any combination. This unit then compares the set points during each scan. An outof-range value is reported on the main display and data files. You can also assign any alarm point to any of six TTL alarm outputs.

Math channels

Each channel measurement can be set to scale and record your measurement using mx+b gain and offset calculations that are available during your channel setup menu. In addition, the mainframe has 20 internal math channels with alarm settings for more complex calculations that record results to your data file during each scan. Each channel result can be used as a variable in another math channel calculation.

DMM mode adds functionality and value

Based on a 6.5 digit (22-bit) precision digital multimeter measurement engine with exceptional measurement quality and resolution—so when you are not using your unit to collect multi-channel data, you can use it as a precision digital multimeter. Front-panel DMM-style input jacks and dedicated DMM menu selections enable you to measure dc voltage, dc resistance, ac voltage, ac resistance, Ohms, frequency, and temperature (thermocouples, RTDs and thermistors). Record DMM measurements to a separate DMM data file for later viewing. It also displays measurement statistics and graphs measurements right on the main display.

USB and internal memory

Features 20 mb on-board memory for storing over 75,000 data records and configuration files. In addition to this large on-board memory, a built-in USB port is available to collect and store large files directly to a USB flash drive. An on-board file management menu makes moving data files or configuration files from internal or USB memory to your PC easy.

Memory management

The main panel memory key opens a simple menu for managing data files and setup files. If you want to load a previously saved setup file for a test, simply select your file from either internal memory or from a USB drive and you are ready to start scanning. You can easily move stored internal data to a USB for PC analysis or move setup files to another unit. With this instrument you have easy access to data without the need for a direct PC connection.

To help safeguard your test data in the case of a power outage, the data acquisition system has a menu selection to resume scanning in the same configuration immediately when power is restored. It is just another way this unit works with and protects your data.

Flexible triggers and resolution

To begin a scan, you have several options that can be set in your test setup menu:

  • External trigger
  • Remote SCPI command
  • Alarm trigger
  • Time interval trigger
  • Manual trigger initiated from the front panel

Measurement resolution is at your control with this product. You can choose between standard settings of Fast, Medium or Slow (4.5, 5.5, 6.5 digits) for the resolution you need. You can also select custom measurement speeds on individual channels to get the accuracy and resolution to suit your requirements.

Totalizer

A totalizer input located on the rear panel provides a simple counter that records to the data file on every scan. The totalizer count can accumulate up to 1,048,575 counts and be reset from the front panel or remote command.

Channel statistics

Each channel's measurement statistics can be viewed at any time. During scanning, monitoring or in DMM mode, you have rate-of-change (per minute and per second), standard deviation, minimum, maximum, peak-topeak, and average—all available at the touch of a button.

Connectivity

USB (virtual serial port) and LAN interface connections are available for easy connection to your company network or direct to you PC. Use Fluke DAQ application software for the 2638A or develop your own interface with the standard SCPI command set, or use our Lab View driver or Indusoft Web Studio to support your specific application needs.

Category II international safety ratings

General purpose portable data acquisition system with an IEC Category II safety rating to help protect you and your operators when making real-world measurements on machinery in industrial areas. Other data loggers that are not clearly rated for these types of category measurements should be reviewed before being used for industrial measurement.

Data security

If you use this unit in a regulated industry, you will appreciate the data traceability feature option in the instrument setup menu. This two level (administrator/ authorized user) system allows an administrator to assign up to five authorized users. The system provides an authenticated record of the operator of any recorded data. Both setup files and resulting data files contain the authorized user ID and timestamp. Guest users may use an existing secured setup file but cannot make changes, and any resulting data file carries the non-traceable label of “Guest.”

Straightforward and only requires a password to access the calibration menu from the front panel. This product can be calibrated manually following the internal menu or by using automated procedures with Fluke Calibration MET/CAL® Calibration Management Software.

Built-in relay maintenance counter

The key to the isolation and accuracy of this unit in part comes from the use of high-quality switching relays inside the unit. Because these relays do deteriorate with extended use, this instrument has a maximum relay counter for each installed relay board. This will assist a user in anticipating when replacing the relay board may be advisable.

Trend Link Software extends system capabilities

Optional Trend Link software is a comprehensive and powerful trend plotting software package. It allows you to access, view and analyze tremendous amounts of historical and real time data in a trending or chart recorder-like display. With Trend Link software, you can zoom in on points of interest in your data, or zoom out to display a wide overview of long-term trends.

Accurate industrial thermocouple measurement

Incorporates the Fluke patented Universal Input Connector to bring more accuracy to thermocouple measurements than most other instruments in its class. The Universal Input Connector supports 14 common thermocouple types. Temperature-focused menu selections make the 2638A especially suitable for temperature validation applications. If you need to zero a large number of thermocouples to a known reference temperature before starting a temperature profiling or validation test, this data acquisition system will normalize all readings to your reference channel at the push of a button and store the offsets for reference in a supporting data file. If you are conducting chamber tests, heat treating tests under AMS guidelines, or validating temperature devices under 21 CFR regulations.

Universal input connector

The universal input connector plugs into any open slot in this unit that contains a relay card. The universal input connector has 22 input channels (20 universal inputs and 2 dedicated, lowburden input current channels). Each input connector contains a CJC (cold-junction compensation) device, which is calibrated at the factory. The calibration date and input connector serial number are programmed into the input connector and are read by this instrument when installed. This information is saved in the test setup data file, which is available for review with any associated scan data from a test setup. This feature is a valuable form of traceability if you are working in a regulated industry.

Wiring a test or system setup for 20 to 60 or more channels can be time consuming. With the inexpensive plug-in Universal Input Connector, you can wire your system once, quickly disconnect the connector from your Hydra, then reconnect the Hydra to another input connector for use in a different area.

Other data loggers require you to wire your inputs directly to an expensive “plug-in” active component signal conditioning module. If you need your instrument for another test at another location, you must remove your wiring or use another expensive plug-in signal conditioning module. With this product, all your signal conditioning is inside the mainframe, not in your input connector.

Using multiple low-cost Universal Input Connectors gives you the flexibility to leave your input connector at the test site, completely wired, and ready to use. When you need data from that site, simply plug in and load your saved setup file. It's that simple!

Expandable channel capacity

Comes with three slots in the rear panel. Each slot can hold a user accessible relay card and a 22-channel Universal Input Connector.

Three configurations are available, from 22 channels to 66 channels per mainframe. Select a base model with 22 channels and add 22-channel expansion kits when needed.

Graphical color display with easy-to-use menus

Never get lost again in a complex menu tree while configuring channels or setting up a test. The large, full color, thin film diode (TFD) display enables this unit to display comprehensive easy-tounderstand data and easy menu navigation.

Back-lighted function keys quickly confirm the active menu selection. The “Record” key illuminates to indicate when the 2638A is recording data in scan, monitor or DMM mode. You always have visible confirmation when your data is being recorded.

Copy-and-paste channel functions make repetitive channel setups a simple task. Top-of-screen menu bar headings always let you know where you are in the setup process.

View your data with the push of a button. Page through all channel data and alarms in a quick view mode or scroll through channels and channel statistics individually. Statistics include rate of change, min, max, standard deviation, average, sample size and peak-to-peak information.

Real-time data charting with historical review

Chart the real-time data of up to four channels at once. Simply select your channels and view real time charts of your measurements. The chart will auto scale for best fit of the displayed values. Zoom in or out to view areas of interest with the push of a button. A history mode enables you to scroll through previously collected data within the scan file—all without a PC and expensive charting programs.

Language support

All displayed text in the menus and data display area are translated to eight languages. You can change the language under the instrument setup area with the push of a button. French, Spanish, Japanese, German, Korean, English, Portuguese, Chinese and Russian are all supported languages in this product.

Screen capture function

With one key push on the front panel, you can capture the screen contents of directly to the USB drive in .jpg file format. Capture trend chart results or data displays for reports or just closer review.

Two alarms per channel

Each channel can be set for two alarm points: High-High, High-Low or Low-Low, in any combination. This unit then compares the set points during each scan. An outof-range value is reported on the main display and data files. You can also assign any alarm point to any of six TTL alarm outputs.

Math channels

Each channel measurement can be set to scale and record your measurement using mx+b gain and offset calculations that are available during your channel setup menu. In addition, the mainframe has 20 internal math channels with alarm settings for more complex calculations that record results to your data file during each scan. Each channel result can be used as a variable in another math channel calculation.

DMM mode adds functionality and value

Based on a 6.5 digit (22-bit) precision digital multimeter measurement engine with exceptional measurement quality and resolution—so when you are not using your unit to collect multi-channel data, you can use it as a precision digital multimeter. Front-panel DMM-style input jacks and dedicated DMM menu selections enable you to measure dc voltage, dc resistance, ac voltage, ac resistance, Ohms, frequency, and temperature (thermocouples, RTDs and thermistors). Record DMM measurements to a separate DMM data file for later viewing. It also displays measurement statistics and graphs measurements right on the main display.

USB and internal memory

Features 20 mb on-board memory for storing over 75,000 data records and configuration files. In addition to this large on-board memory, a built-in USB port is available to collect and store large files directly to a USB flash drive. An on-board file management menu makes moving data files or configuration files from internal or USB memory to your PC easy.

Memory management

The main panel memory key opens a simple menu for managing data files and setup files. If you want to load a previously saved setup file for a test, simply select your file from either internal memory or from a USB drive and you are ready to start scanning. You can easily move stored internal data to a USB for PC analysis or move setup files to another unit. With this instrument you have easy access to data without the need for a direct PC connection.

To help safeguard your test data in the case of a power outage, the data acquisition system has a menu selection to resume scanning in the same configuration immediately when power is restored. It is just another way this unit works with and protects your data.

Flexible triggers and resolution

To begin a scan, you have several options that can be set in your test setup menu:

  • External trigger
  • Remote SCPI command
  • Alarm trigger
  • Time interval trigger
  • Manual trigger initiated from the front panel

Measurement resolution is at your control with this product. You can choose between standard settings of Fast, Medium or Slow (4.5, 5.5, 6.5 digits) for the resolution you need. You can also select custom measurement speeds on individual channels to get the accuracy and resolution to suit your requirements.

Totalizer

A totalizer input located on the rear panel provides a simple counter that records to the data file on every scan. The totalizer count can accumulate up to 1,048,575 counts and be reset from the front panel or remote command.

Channel statistics

Each channel's measurement statistics can be viewed at any time. During scanning, monitoring or in DMM mode, you have rate-of-change (per minute and per second), standard deviation, minimum, maximum, peak-topeak, and average—all available at the touch of a button.

Connectivity

USB (virtual serial port) and LAN interface connections are available for easy connection to your company network or direct to you PC. Use Fluke DAQ application software for the 2638A or develop your own interface with the standard SCPI command set, or use our Lab View driver or Indusoft Web Studio to support your specific application needs.

Category II international safety ratings

General purpose portable data acquisition system with an IEC Category II safety rating to help protect you and your operators when making real-world measurements on machinery in industrial areas. Other data loggers that are not clearly rated for these types of category measurements should be reviewed before being used for industrial measurement.

Data security

If you use this unit in a regulated industry, you will appreciate the data traceability feature option in the instrument setup menu. This two level (administrator/ authorized user) system allows an administrator to assign up to five authorized users. The system provides an authenticated record of the operator of any recorded data. Both setup files and resulting data files contain the authorized user ID and timestamp. Guest users may use an existing secured setup file but cannot make changes, and any resulting data file carries the non-traceable label of “Guest.”

Straightforward and only requires a password to access the calibration menu from the front panel. This product can be calibrated manually following the internal menu or by using automated procedures with Fluke Calibration MET/CAL® Calibration Management Software.

Built-in relay maintenance counter

The key to the isolation and accuracy of this unit in part comes from the use of high-quality switching relays inside the unit. Because these relays do deteriorate with extended use, this instrument has a maximum relay counter for each installed relay board. This will assist a user in anticipating when replacing the relay board may be advisable.

Trend Link Software extends system capabilities

Optional Trend Link software is a comprehensive and powerful trend plotting software package. It allows you to access, view and analyze tremendous amounts of historical and real time data in a trending or chart recorder-like display. With Trend Link software, you can zoom in on points of interest in your data, or zoom out to display a wide overview of long-term trends.

Webinar: Introduction to Portable Precision Power Analyzers with Fluke


This wideband precision analyzer is accurate enough for the lab, yet it's built for the field. Offering you more freedom than ever before to make high accuracy power measurements wherever you need to. Whether in the lab, or in the field. Designed for portability and eliminates the need to carry large, fragile, expensive analyzers into the field, allowing you to make measurements directly at the load in nearly any environment. By measuring directly at the load, you can discover how the equipment operates under real-world conditions, with real-world variables, not just at a test bench or in the lab.
During our 1-hour webinar, we've covered:
- The new Fluke Norma 6000 Power Analyzer for accurate measurements at frequencies from DC to 500kHz.
- It is not a Power Quality Analyzer.
- It is a Power Analyzer for accurate measurements at frequencies from DC to 500kHz.
- It is designed to be used in the field, its rugged, battery-operated, lightweight, and suited to use outside of a laboratory environment.
- You’ll learn why it can help you, where and how it is used.
