Canceling auto-range operation
• When the measurement range is set to auto-range operation, the output rate for analog and waveform
output will vary with the range. When measuring lines for which measured values fluctuate excessively,
exercise care so as not to mistake range conversions. It is recommended to use a fixed range for this type
of measurement.
• Voltage and current are displayed from 0.5% to 140% of the range.
• Active power is displayed from 0% to 196% of the range.
• Display range values have an error of ±1 dgt. due to calculation precision.
• When integration is started, auto-range operation will be canceled, and the range at that point will be fixed.
• The range will not change during display hold or maximum value/minimum value hold operation.
