Range Resolution Accuracy

10Hz~10MHz 0.01Hz~0. 01MHz ±(0.1%+4dgt)

0.1%~99.9% 0.1% --

Overload protection: 600Vrm

Input amplitude: (DC level is 0.)

10Hz~1MHz: 300mV ≤ a ≤30Vrms

>1MHz~10MHz: 600mV ≤ a ≤30Vrms

Input amplitude and frequency response must meet following conditions when

reading frequency or duty cycle during AC voltage or current measurement

• Input amplitude ≥ Range × 30%

• Frequency response: ≤400Hz
