When measuring capacitance, for the 4000 uF range, the measuring duration should be over 30
seconds.
3
When measuring frequency, the typical waveform is Square or Sine. The signal meets the following
conditions.
Frequency Amplitude (rms)
1 Hz – 4 MHz 100 mV
4 MHz – 8 MHz ≥ 200 mV
8 MHz – 10 MHz ≥ 300 mV
4
When measuring duty cycle, the typical waveform is Square.
