You are purchasing TWO FUSES

DON'T BE FOOLED
Only Genuine Fluke Fuses say "DMM-44/100 and DMM-11A" on the label!

 ONE New 440mA (44/100 Amp) High Voltage fuse AND ONE  New 11 Amp High Voltage fuse. They are both used to protect the current measurement circuitry in the following Fluke Digital Multimeters:

23-3, 26-3, 27 (Serial Numbers greater than 7211001), 77-3, 79-3, 83, 85, 87 (SN's greater than 6565001), 83-3, 85-3, 87-3, 87E-3, 87-4, 89-4, 175,177, 179, 187, 189, 787, 863, 865, 867 and 867B

To check these fuses in your meter, point the rotary function switch to the V~ (AC Voltage) function and insert a lead first into the "mA/uA" connector and then into the "A" connector on the front of the meter.  If you hear a "chirping" sound, the fuse corresponding to that current measurement circuit is good.  If you don't hear a sound, the fuse is defective - assuming the meter "beeper" is OK...

If you need email assistance removing the cover to replace the fuses, I will respond promptly.

Shipping within the United States via USPS is FREE!. Shipping costs to Australia, Canada and Europe are posted under the shipping tab.  If you live elsewhere email for a shipping quotation before you purchase the fuse.
