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, allowing the
appropriate input signals to be applied.
The error message might be caused by any of the following conditions:
• Input signal is not connected to the proper terminals or it is connected backwards
• Wrong signal selection in Setup menu
• Minimum input span requirements not maintained
• Input 1 signal inadvertently applied to calibrate input 2.
