Figure 3–69: Probe Cal Menu and Gain Compensation Display
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).
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.
12. If the Probe Offset Compensation message is displayed, continue with step
16; otherwise, continue with step 13.
13. If the Compensation Error message is displayed, continue with step 14;
otherwise continue with step 19.
14. Press SHIFT UTILITY ➞ System (main) ➞ Diag/Err (pop-up) ➞ Error
Log (main). If there are too many error messages to be seen on screen, rotate
the general purpose knob clockwise to scroll to the last message.
