4. MAINTENANCE
The instrument has no parts that can be replaced by personnel who are not trained and
approved. Any non-approved repair or other work, or replacement of a part by an
"equivalent", may severely compromise safety
4.1 Cleaning
Periodically wipe the case with a damp cloth and mild detergent. Do not use abrasives or
solvents. Dirt or moisture in the terminals can affect the readings. Dry the meter perfectly
after cleaning and before use.

mA/µA according to the fuse to be
tested
A good A terminal fuse is indicated
000.0Ω to 000.2Ω.

fuse and test again
4.
