Checking the Probe Compensation
NOTE
Always compensate a probe for the particular channel that you use
it with.
Use the following procedure to check the probe compensation:
C]
Step 1:
Set the instrument controls as described in Setting up the
Display.
C]
Step 2:
Connect the probe to the channel you intend to use it for.
(If the probe is properly "coded" the volts-per-division readout for the chan-
nel will change to match the attenuation factor of the probe. The
10X
probes
supplied with the oscilloscope already have the proper coding.)

Step 3:
Clip the probe tip to the
PRB ADJ
connector.

Step
4:
Use the
VOLTSIDIV
control to display about
5
divisions of the
waveform.
Step 5:
Use the
VERTICAL POSITION
and
HORIZONTAL POSITION
controls to center the display.
Step
6:
Check the waveform against Figure
1-3
to see if the probe is
correctly compensated.
