Basic Measurement Specifications
5.3 Measurement specifications
Measurement method Simultaneous voltage and current digital sampling, zero-cross simultaneous calculation
Sampling frequency Approx. 700 kHz
A/D converter resolution 16-bit
Frequency bands DC, 0.1 Hz to 100 kHz (Reference value of 0.1 Hz
≤
f < 10 Hz)
Synchronization sources
(SYNC) U1, U2, U3, I1, I2, I3, DC (fixed at 200 ms)
Can be set separately for each wiring mode.
When the source input AC measured value is less than 1% f.s., operation and accuracy
are not defined.
When synchronization cannot be detected, the SYNC ERROR lamp will light up.
Operation and accuracy are not defined at that time.
When the synchronization source is DC, accuracy is not defined for input with a cycle
that is not divisible by 200 ms.
Synchronization timeout setting: 0.1 sec. / 1 sec. / 10 sec. (linked to measurement lower
limit frequency setting)

monic measurement
Zero-Crossing Filter 100 Hz/ 500 Hz/ 5 kHz/ 200 kHz (linked to frequency measurement range)
100 Hz:
0.1 Hz to 100 Hz
500 Hz: 0.1 Hz to 500 Hz
5 kHz: 0.1 Hz to 5 kHz
200 kHz: 0.1 Hz to 200 kHz
The zero-cross filter lower limit setting is linked to the synchronization timeout setting.
