10Hz~1MHz ± (0.1%+4)
Overload Protection: the same as AC/DC voltage, DC millvoltage, AC/DC Current, and
RPM mode.
Input Amplitude: a
1) AC/DC voltage mode,
When 40Hz ~ 1KHz: a ≥range x 10% (except 1000V range)
a ≥400V (1000V range)
When 10Hz ~40Hz or 1k Hz ~1MHz: for refer only.
2) AC/DC Current mode,
When 40Hz ~ 1KHz: a ≥range x 10% (except 10 A range)
a ≥4A(10 A range)
When 10Hz ~40Hz or 1k Hz ~1MHz: for refer only.
3) DC millvoltage mode,
When ≤ 100KHz: 40mV ≤ a ≤ 200V rms
When 10Hz ~1MHz ~1MHz: 200mV ≤ a ≤ 10V rms
