Auto-range operation
During auto-range operation, the range is switched as described below:
The voltage and current display range is 0.5% to 140% of the range.
When the measured value is less than 0.5% of the range, the zero-suppression function forces the value to be
displayed as zero.
Range increased Range decreased
• When the measured value exceeds 130% of
the range
• When the PEAK OVER lamp lights up
When the measured value is less than 15% of the range
(The range will not be decreased when the value would exceed the
peak value for the next lower range.)
• When performing measurement using multiple channels, for example as with the 1P3W or 3P3W wiring
modes, the range will be increased when any of the range increase conditions are satisfied.
• The range will be decreased when all of the range decrease conditions are satisfied.
These errors indicate that the instrument was unable to switch ranges. Take the following action to
address the error:
