Error Message (
Err
)
An error message indicates that the calibration or scaling process was
not successful.
After the error message is displayed, the meter reverts to input 1, allow-
ing acceptable input voltages to be applied or valid data to be entered.
The error message might be caused by any of the following conditions:
1. Input signal is not connected to the proper terminals or it is con-
nected backwards.
2. Input span was less than 10 VDC.
3. Same input signal used for both calibration points.
