Method,
the meter must be calibrated with an external calibrator.

2. InPt 1 flashes. Apply input 1 signal (e.g. 4mA, 1V, etc.) then push
ENTER, Program desired display for input 1.
3. InPt 2 flashes. Apply input 2 signal (e.g. 20 mA, 10 V, etc.) then
push ENTER. Program desired display for input 2.
Calibration Error (Error)
A meter display of Error during calibration indicates that the
calibration process was not successful and the meter needs to be
recalibrated.
1. The Error message will appear if input 1 signal and input 2 signal
are too close together, see Table 2 on page 22.
2. The Error message will appear if input 1 signal is inadvertently
also applied for input 2 calibration, or ENTER is pushed before
applying input 2.
Programming Confirmation
The values that have been programmed can be quickly checked to
make sure they are the desired values. To do this, apply the desired
signal for each point and check the display.
