Figure 3–69: Probe Cal Menu and Gain Compensation Display
H If gain compensation did not complete successfully, you may get a
“Probe is not connected” message (examine the probe connections to the
digitizing oscilloscope, be sure the probe tip is properly installed in its
retractor, etc., and repeat step 10).
H If gain compensation did not complete successfully, you may get the
message “Compensation Error.” This error implies that the probe gain
(2% error) and/or offset (50 mV) is too great to be compensated. You can
substitute another probe and continue. Have your probe checked by
service personnel.

otherwise continue with step 19.
