measurement. Do not remove the probe from the measuring instrument after the object of
measurement is connected.
Handling of the passive probe
Do not touch the probe’s input terminal or the probe itself with wet hands.
Make sure not to exceed the oscilloscope’s maximum input voltage in the following
cases:
• When the probe attenuation ratio is 1:1
• When the oscilloscope’s input coupling is AC
DC voltage of the same electric potential as the probe’s input is applied to the
oscilloscope’s input.
Do not operate with suspected failures
If you suspect that there is damage to this probe, contact your nearest YOKOGAWA dealer
or sales representative.
Do not operate in wet/damp conditions
To avoid electric shock, do not operate this probe in wet or damp conditions.
