Procedure
1. Choose the analog input to calibrate, either temperature or pressure and click Next.
The Current|Calibration screen shows the current offset and gain and the input
scaling (i.e., the pressures or temperatures corresponding to the minimum (4 mA)
input and maximum (20 mA) inputs).
2. Click Next to proceed to the Calibration|Method screen then, select either the
offset or two-point calibration methods.
• The Offset method requires a single calibration point and only affects the input's
calibration offset parameter.
• The two-point calibration requires calibrating at two different points (ideally far
apart in value) and affects the input's calibration offset and gain parameters.
Depending upon the selected calibration method, either one or two screens will
follow when the Next button is clicked.
3. The screen(s) displays the current (live) reading. When the input is stable, click the
Hold button to freeze the current reading.
4. Enter the correct value in the Actual edit box. Finally, the Finish screen shows the
new calculated offset and gain values.

5. Click Finish to write the values to the meter. If the meter is not configured to use live
values from the analog input for calculation, a prompt displays asking if the
configuration should be changed to use the live input.
