If Your GMM Does Not Work
NOTE
If the display remains blank after pressing
W
, contrast may be off the scale. Restore
contrast to mid-scale with the following
shortcut: set the selector to SET UP and
avoid touching any key until the display
reappears (about 15 seconds). Press
5
to store this setting, then turn the selector to
the desired function.
Examine the case for physical damage. If damage is
detected, contact a Fluke Service Center. Check and
replace (as needed) the battery, fuses, and test
leads. Review this manual to verify correct operation.
If the GMM still does not work, pack it securely and
forward it, postage paid, to the nearest service
center. Include a description of the problem. Fluke
assumes no responsibility for damage in transit.
A GMM under warranty will be repaired or replaced
(at Fluke’s option) and returned at no charge. See
the registration card for warranty terms. If the
warranty has lapsed, the GMM test tool will be
repaired and returned for a fixed fee. Contact the
nearest service center for information and prices.
If “Uncal” appears in the Upper Status Line, the
GMM is no longer calibrated; contact a Fluke Service
Center.
