Error Message (Error)
An error message indicates that the calibration or scaling process was
not successful.
After the error message is displayed, the meter reverts to input 2 during
calibration or scaling and to input 1 during internal calibration, allowing
the appropriate input signal to be applied or programmed.
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
connected backwards.
2. Wrong signal selection in Setup menu.
3. Minimum input span requirements not maintained.
Minimum Input Span
The minimum input span is the minimum difference between input 1 and
input 2 signals required to complete the calibration or scaling of the meter.
Input Range Input 1 & Input 2 Span
+/- 0-5 ADC +/- 0.005 ADC
0-5 AAC 0.010 AAC
+/- 0-300 VDC +/- 0.1 VDC
0-300 VAC 0.3 VAC
