Function
Maximum rated input
WARNING
1. Never apply a voltage signal exceeding the maximum rated input value.
2. Do not turn the rotary switch to change the function during measurement.
3. Always keep your fingers behind the finger guards on the test
lead when making a measurement.
Note:
●The duty ratio measurement range is from 20 % to 80.0 %.
The input signal condition is: Zero-cross pulse signal of 5 Hz to
1 kHz, 5 Vp-p to 60 Vp-p.
The zero-cross pulse refers to a pulse-waveform signal
changing the polarity in order of (+ potential → - potential → +
potential). This instrument cannot measure a signal composed
of the + potential alone, such as the logic pulse, or the –
potential alone.
● If the measured frequency contains noise, the measurement
values may become unstable.
●
The bar graph is not displayed with the duty ratio measurement.
The measurement is possible only with the auto range.
