5. Maintenance
5.1 General maintenance
This section provides basic information on both the maintenance of the
multimeter and the replacement of the fuses and battery. Only experienced and
authorised personnel should carry out repairs to the multimeter.
WARNING
To avoid injury or damage to the multimeter, do not allow moisture to enter the
housing and remove the test leads before opening the battery cover.
• Use a damp cloth to regularly clean the outside of the multimeter. Do not use
abrasives or chemical solvents. A dirty or wet input terminal may adversely
affect the reading.
• To clean the input terminals, follow the steps below:
1) Turn off the instrument and remove the test leads.
2) Clean any dirt or other particles from the inlet terminals.
3) Use a cotton or swab with lubricant to clean the inlet terminal contacts.
4) Use a separate cotton ball or swab for each terminal to avoid cross-
contamination.
5.2 Battery and Fuse Replacement
1) Under normal conditions, it is not necessary to replace the fuse. Do not
replace it until the test probes are unplugged and the power is turned off.
Remove the two rear cover screws to remove the housing.
2) The specification of the fuse is:
F1: F 10A H 250V, F2: F 250mA H 250V
The replacement must be of the same specification.
3) The battery of this multimeter is 9V NEDA 1604 or 6F22. The replacement
must be of the same specification.
4) Do not put the instrument into use until the back cover is screwed on after
replacing the battery or fuse.
WARNING
To avoid an electric shock, make sure that the test probes are disconnected
from the circuit being measured before removing the rear cover. Make sure
the back cover is screwed on tightly before using the instrument.
