Viewing calibration values for analog inputs or RTD

You can view calibration values for specific analog inputs or for the RTD. You can also view AI
calibration data in the event log. See Section 8.4.2 for information on viewing the event log.
To view calibration values:
1. Click
Utilities > AI Calibration Values
Configuration and Use Manual
Verify a calibration, using fifteen midpoints. The analog input has a
range of 100 to 500 EUs.
Calculate the EU value to be associated with each midpoint, to
produce a table similar to the following:

Verify the zero point:
1. Enter a value of 100 in the Dead Weight/Tester Value field.
2. Set the input from the test device to 4 mA.
3. View the live reading.
4. Click !Log Verify.
Verify the span:
1. Enter a value of 500 in the Dead Weight/Tester Value field.
2. Set the input from the test device to 20 mA.
3. View the live reading.
4. Click !Log Verify.
For each midpoint:
1. Enter the EU value in the Dead Weight/Tester Value field.
2. Set the input from the test device to the associated mA value.
3. View the live reading.
4. Click !Log Verify.
. The dialog box shown in Figure B-3 is displayed.
