Notes for frequency specifications:
1 The input signal is lower than the product of 20000000V×Hz (product of voltage & frequency); overload protection: 1000 V.
2 For non-square wave signals, an additional 5 counts need to be added.
3 The multimeter will automatically select the most appropriate range when making frequency measurements.

Duty Cycle and Pulse Width Specifications

Function
Duty cycle
Notes for duty cycle specifications:
1 The accuracy for duty cycle and pulse width is based on a 5 V square wave input into the DC 5 V range.
2 For AC coupling, the duty cycle range can be measured for signal frequency > 20 Hz.
