Fluke 1586A Application Note

Automating temperature
sensor calibration with the
1586A Super-DAQ
Take your calibration lab productivity to the next level
The 1586A Super-DAQ Precision Temperature Scanner provides a unique feature for automat­ing sensor calibration that can greatly increase your lab productivity—without a PC and soft­ware. When the Super-DAQ is connected to a Fluke Calibration dry-well or fluid bath, it can control the temperature source to run the calibration automatically. You simply program the number of set-point temperatures and their values, select a scan sequence, assign a refer­ence channel, and set the required stability band.
The Super-DAQ monitors the temperature source’s stability through the reference chan­nel, collects the data from the reference probe and the “unit under test” (UUT) once stabi­lized, and then advances to the next set-point temperature.
After you configure and start the test, you can walk away to work on other things. The Super-DAQ just made your day a whole lot easier!
One temperature source can be connected to the Super-DAQ at a time. The Super-DAQ can control all of the following Fluke Calibration models:

How to set up an automated sensor calibration
Step 1: Connect the RS-232 cable
Connect a DE-9, null-modem, female-female RS-232 cable from the Super-DAQ rear panel to the RS-232 port of the temperature source. Ensure that the baud rate of the temperature source matches the Super-DAQ. The default is
9600. You can designate any channel as the reference probe including the front panel chan­nel (Ch 001).
Note: The Super-DAQ does not record temperature data from the temperature source’s controller or Process Electronics input. All measurement, stability monitoring, and data collection are done through the Super-DAQ.
Press the Edit Channel soft key, set Function to Thermocouple, Thermistor, or PRT. Choose the appropriate parameters for the function selected. Configure additional channels. Press Back when finished.

Step 2: Select the channels
Press the Channel Setup hard key, select a channel to be enabled and press ON (F2).
Step 3: Select test parameters
Press Test Setup. Change the Trigger Type to Automated Test, enter the Scan Count, set the Sequence to Linear, Alternate Reference, or
Up/Down.
Linear Sequence – Scans the first reference
channel (Ref1), then all of the enabled chan-
nels in ascending channel order, followed
by the optional second reference channel
(Ref2). For example: Ref1 > Ch102 > Ch103
> Ch104 > Ref2.
Alternate Reference Sequence – Scans the
first reference channel (Ref1), then a single
channel, followed by the optional second
reference channel (Ref2). The sequence then
repeats for the other enabled channels. For
example: Ref1> Ch102 > Ref2 > Ref1 >
Ch103 > Ref2 > Ref1 > Ch104 > Ref2.
Up/Down Sequence – Scans the first
reference channel (Ref1), then the enabled
channels in ascending channel order, fol-
lowed by the optional second reference
channel (Ref2). The sequence is then imme-
diately repeated in reverse, descending
order. For example: Ref1 > Ch102 > Ch103
> Ch104 > Ref2 > Ref2 > Ch104 > Ch103 >
Ch102 > Ref1.

Designate a Reference Channel, and turn Con- trol Source On. The default is Off, so don’t skip this step.
Note: If Auto Recording is On (Test Setup menu), data will be recorded automat ically. If Auto Recording is Off, you can press the Record key once the scan has been started to manua lly capture data.
Step 4: Choose setpoint temperatures
Press Setpoints. Select Setpoint 1 and enter Setpoint Temperature, Tolerance, Stability,
and Soak Time. Press New to add additional setpoints.
Note: The number and value of setpoint temperatures is dependent on your source.
Step 5: Start the scan
Press the Scan/Monitor key and select Start Scan.
Step 6: Collect data
The Automated Test state will display a Scan Status of “Settling” while the temperature
source is stabilizing. After the source has stabilized, the Automated Test state will then display a Scan Status of “Scanning” while the data is being collected. Data can be written to internal memory or a USB flash drive during a test. You can select Data, Graph, or Monitor view modes during data collection.

Step 7: Analyze data
Once the data has been collected, it can be transferred to a PC as an Excel .CSV file for analysis.
Conclusion
The automated sensor calibration feature of the 1586A Super-DAQ can have a big impact on your calibration lab throughput and efficiency. It comes in real handy when you have lots of sensors to calibrate and limited time and staff to do it. No extra training on software packages is needed.
Once you set up a Super-DAQ automated test, you can move on to other work that needs to get done. The Super-DAQ controls the tem­perature source and gathers calibration data automatically—all within the parameters you’ve specified.
