3. Check the probe whether it’s connected with the device
under test (DUT) or not.
4. Check the tested DUT to see if it produces the signal or
not.
5. Try to probe the DUT for signal again.
3. The value of the tested voltage is 10 times higher/lower than
the real one , please do the following:
Check the attenuation quotient whether it matches the
probe attenuation proportion or not.
4. Display the wave, but not steady , please do as following steps:
1. Check the signal source on the trigger interface whether
or not it matches the signal channel.
2. Check the trigger mode: normal signal should use the
“edge” trigger mode. The video signal should use the
“Video” Trigger mode. The signal would display steadily
only when using matching trigger mode.
3. Attempt to change the “coupling” into “HF Reject” or
“LF Reject” display, so that the High/low frequency
noise will be filtered.
5. Press “RUN/STOP” button, but no display.
