Calibration Procedure

The calibration procedure for an auxiliary analog input will be the same regardless of which operation is being performed.

1. Zero Input: Source a zero mV value to the terminals.  Press the Calibrate button.

2. Span Input: Source a specific mV value to the terminals and enter the value in the box.  Press the Calibrate button.

3. Cold Junction Trim:  Enter the temperature of the input.

 

The user will need to select which calibration type – Zero/Span or Cold Junction – is to be performed and press the appropriate button from the main calibration screen.  The cold junction trim value must be performed, if necessary, after the zero and span calibration.
