User Maintenance

Cleaning

Clean your Tester with a damp cloth and a mild detergent. Do not use
abrasives, solvents, or alcohol.

Fuse Replacement

The Tester uses electronically protected inputs; no fuses are required.

Battery Replacement

To avoid electrical shock, disconnect the voltage test
leads and the current probe before replacing the batteries.
The Tester must be disconnected from all sources before
you can open it for any adjustment, battery replacement,
maintenance, or repair.
The Tester uses four alkaline C cells (supplied). You can also use four
rechargeable NiCad batteries, which you must supply. (The Tester does not
provide for internal recharging.)
Used Nickel-Cadmium batteries should be disposed of by a qualified
recycler or hazardous materials handler. Contact your authorized
Fluke Service Center for recycling information.

screws with a flat-blade screwdriver.
