NOTE
. If your oscilloscope has a probe calibration routine, run it
before making any of the following checks. Refer to the oscilloscope’s
instruction manual for more information.
Offset Zero
Use this procedure to verify the probe’s offset zero.
1.
Ground the probe tip by connecting the probe tip to the probe
ground socket. (Connecting the two KlipChip adapters together is
recommended.)
2.
Set the channel’s vertical offset to 0.00 V.
3.
Measure the displayed DC level.
The displayed DC level should be 0.00 V
±
50 mV. (
±
5 mV when
measured directly without the probe attenuation factor.)
