The EA001A Thermocouple Calibration Adapter connects to the 3000A/4000 Range of calibrators and offers either :
> Automatic Compensation (using a built-in temperature sensor at the point of connection)
> Manual Compensation (manually entered using the calibrator keypad or using ProCal)
To allow ProCal to display the cold junction selection control panel, a test must be set to show a test prompt before the test starts.
To do this, follow the steps below :
STEP 1 : Edit the procedure using ProEdit (set the 'before test prompt' to be displayed)
File > Edit an Existing Procedure
Select the procedure to edit by seraching for, for example, a model number (or click START SEARCH to view all procedures):
Select the peocedure to edit, then click ACCEPT :
Step through the procedure instrument information screens and edit the test lines as shown below :
Click NEXT to continue through to the uncertainty statements and traceable instruments screen
Click NEXT to proceed to the test edit screen
The test edit screen will be displayed - click the TEST LIST button to view all tests :
Select the first temperature test in the list, then click OK :
Edit the prompt settings by clicking on the PROMPTS tab for this first temperature test and ensure it is set to YES -
if not already set, you may like to enter some prompt test such as 'Please check the cold junction value'
STEP 2 : Run ProCal
ProCal will display the 'before test prompt' for the tests configured (as above) -
the prompt screen displayed before the test will display the cold junction settings as shown below :
Select the cold junction compensation mode as required.
