Automatically setting the range (auto-range operation)
Selecting auto-range operation causes the range to be switched automatically according to the measured
value. This feature is convenient when you do not know the range.
See: Auto-range operation (p.50)
Press any range key or again and then press (voltage range) or (current
range).
Setting auto-range operation
1 Press to activate the shift state.
2 Press (to set the voltage range) or (to set the current range).
3 The AUTO lamp and the lamp for the range being measured will light up.
You can check the auto-range setting for individual channels with the STATUS, U AUTO RANGE lamp and
I AUTO RANGE lamp.
e.g.) CH1
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.
