• Instantaneous value, electric energy, demand
If an input exceeds 130% of the rated range, "OR" appears.
Measurement Item Conditions and Indications
Voltage rms If the peak value of an input signal exceeds 300% (180% for
the 1000 V range) of the measurement range, or if the rms
value of measured voltage exceeds 130% of the rated range,
"OR" appears.
Current rms If the peak value of an input signal exceeds 400% of the
measurement range, or if the rms value of measured current
exceeds 130% of the rated range, "OR" appears.
Active power
Reactive power
Apparent power
If power input (active, reactive, or apparent) exceeds 130%
of the rated range, "OR" appears. Also, if the measured value
exceeds the maximum displayable digits, 9999, "OR" appears.
Power factor
Phase angle
If the peak value of a voltage input signal exceeds 300%
(180% for a 1000 V range) of the measurement range;
if the rms value of measured voltage exceeds 130% of the
rated range; if the peak value of a current input signal
exceeds 400% of the measurement range; or if the rms value
of measured current exceeds 130% of the rated range; "----"
appears.
Frequency
If frequency exceeds 70 Hz, the fixed clock is selected.
Interval electric energy
Electric energy
Reactive energy
Even if power input exceeds 130% of the rated range, an
excessive power value (active power, reactive power)
will be integrated. In this case, however, the accuracy of an
integrated value is not specified.
Power demand
Reactive power demand
If a demand input exceeds 130% of the rated range, "OR"
appears. Also, if the measured value exceeds the maximum
displayable digits, 9999, "OR" appears.
Analog input (optional)
2.5 Overrange/Error Indication during Measurement
