Owon OW18 Series - Key Features and Characteristics

7.Technical Specifications
other current should flow through except within the measuring duration.
[3]
When measuring capacitance, for the 60.00mF range, the measuring duration should
be over 30 seconds.
[4]
When measuring frequency, the typical waveform is Square or Sine. The signal meets
the following conditions.
Frequency
Amplitude (rms)
1 Hz – 5 MHz
≥ 700 mV
[5]
When measuring duty cycle, the typical waveform is Square.
Note: when measuring resistance and capacitance, the influence of the resistance reactance of
the pen itself on the measured value should be considered.
