General Maintenance
•
Clean the meter casing with a damp cloth and a mild detergent.
•
Do not use any chemicals, abrasives or solvents that could damage the meter.
•
Dirt or moisture on the terminals can affect readings. Clean the terminals
according to the following steps:
- Turn off the meter and remove all test leads.
- Clean up the dirt on the terminals.
- Soak a clean cotton swab in mild detergent and water and clean each terminal
with the cotton swab. Dry each terminal with canned compressed air to force water
and detergent to flow out of the terminals.
- In case of anything abnormal for the meter, stop using it and send it for repair.
When the meter needs to be verified or repaired, qualified service personnel are
required in order to carry out any work needed.
Testing the Fuse
•
Insert a test lead into the terminal as shown right and contact the
probe tip at the other end of the test lead with the metal in the
terminal of current input.
•
If the message “Lead Error!” (connection error for test lead)
appears, it shows that the probe tip is inserted too deeply into
the terminal of current input.
•
Draw out the test lead a little until the error message disappears
and “OL” (overload) or the resistance reading appears on the
display.
•
If the resistance reading for the “A” terminal is less than 0.5Ω, it
shows that the fuse F2 is normal.
•
If the reading is “OL”, you need to replace F2.
•
If the resistance reading of “µA m” is less than 1.2MΩ, it shows
that the fuse F1 is normal.
•
If the reading is “OL”, F1 needs to be replaced.
Replacing the Fuse
•
Inspect or replace the
fuse
as shown in the figure below right,
according to the following steps:
- Turn off the meter and remove the test leads from the
terminals.
-
Use a flat-head screwdriver to turn the screw anti-clockwise
on the battery cover then remove the battery cover.
•
Gently pry one end of the fuse and then remove it from the
clip.
•
The fuse installed for the mA or µA input terminal is 0.8AH
1000V fuse type 6x32mm (F1), while the fuse installed for the
A input terminal is 10AH 1000V fuse type 10x38mm (F2).
