When gain compensation completes, the following actions occur:
The clock icon will disappear.
If offset compensation is required for the probe installed, the Probe
Offset Compensation message will replace the Probe Gain Compensa-
tion message.
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 9).
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.
