IMPORTANT SAFETY INFORMATION

Date: July 2, 1998

Subject:
FLUKE SERIES III, MODEL 21, 23, 26, 70, 73, 75, 77, 79, & SERIES II MODEL 73 OPERATION SAFETY NOTICE

Dear Fluke DMM Customer:

We have become aware of a product malfunction in certain Fluke digital multimeters (DMMs). These products started shipping on May 15, 1998. Only nine models are affected: the Fluke Series III, Model 21, 23, 26, 70, 73, 75, 77, 79 and Series II, Model 73 meters imprinted on the case bottom with serial numbers between 70800000 and 71100000. No other Fluke instruments are affected.

The malfunction may occur after the DMM has received an impact, such as being dropped, causing part of the function switch to become dislodged from its mounting. Even though in most cases a failure will result in an inoperative meter, it may be possible for the meter to indicate a reading of (or near) zero volts. WHEN THE MALFUNCTION OCCURS, THE METER MAY NOT INDICATE THAT HIGH VOLTAGE IS PRESENT, PLACING THE USER IN A POTENTIALLY HAZARDOUS SITUATION.

To correct this problem Fluke will replace the switch in your meter without charge. Even if you have not experienced this problem, it is strongly recommended that you return your meter for possible switch replacement.

If you are not the primary user of the affected Fluke DMM, please make every effort to pass this notice to the appropriate people within your organization.

Please send your meter to the following Fluke Service Center to have this modification completed. Your unit will be modified and on its way to you within a few days.

NO TELEPHONE CALL OR RETURN MATERIAL AUTHORIZATION (RMA) IS NECESSARY.
