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 the appropriate input signals to be applied.
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. Wrong signal selection in Setup menu.
3. Minimum input span requirements not maintained.
