Measurement accuracy
±0.5% rdg. ±5 dgt. (DC, AC 50 Hz/60 Hz)
When zero suppress is set to OFF, any value less than 10 counts is
outside the guaranteed accuracy.
(When a clamp on sensor is connected, the accuracy of the clamp
on sensor is added.)
Any intermittent current and leak current cannot be measured.
Temperature
characteristics
Measurement accuracy × 0.05/°C (added to the measurement
accuracy when the temperature is outside 23 ± 5°C)
Filter
ON/OFF selection
Frequency
characteristics (-3 dB)
180 Hz ± 30 Hz (with the filter ON)
1 kHz (with the filter OFF)
RMS value calculation
True RMS value calculation by software
(The reversed current is indicated with a - symbol during DC
measurement.)
