Offset Zero Procedure
The CT3681 and CT3683 can be adjusted to zero the probe's offset
voltage using the offset adjustment tool supplied with the probe. Follow
this procedure to perform the offset adjustment.
1.
Connect the probe to Channel 1 of the oscilloscope. Turn
on the probe power. You may use the USB power cable or
batteries to power the probe. Set the probe attenuation ratio
to 100x.
2.
Short the + and - probe inputs together with the hook tips.
3.
Turn on power to the oscilloscope. Leave both the
instrument and the probe turned on for 30 minutes to
stabilize.
4.
Press [Default Setup] and [Auto] on the oscilloscope.
5.
Press the Channel 1 button, then press the Probe softkey
and set the attenuation to 100x.
6.
Set the oscilloscpe to DC coupled mode and the scope
offset to 0 volts.
7.
Set the oscilloscope to average mode (x16) or high-
resolution mode to reduce oscilloscope noise.
8.
Using the offset adjustment tool (included), adjust the probe
offset voltage to 0 volts
