Range Accuracy Resolution
9.999 Hz to 9.999 MHz ±(0.7 % reading +4 digits) 0.001 Hz 0.001 MHz
0.1 % to 99.9 % For reference only. 0.01 %
Input range: (DC level=0)
≤100 kHz: 200 mVrms ≤ Input amplitude ≤30 Vrms
>100 kHz to 1 MHz: 600mVrms ≤ Input amplitude≤30 Vrms
> 1 MHz: 1 Vrms ≤ Input amplitude ≤30 Vrms
Duty ratio %: Only for frequency ≤10 kHz, amplitude >1 Vrms
Duty ratio applies only to ≤10kHz measurements
Frequency ≤1 kHz duty ratio: 10.0 % to 95.0 %
Frequency >1 kHz duty ratio: 30.0 % to 70.0 %
