4. MAINTENANCE
4.1 Cleaning
Maintenance consists of periodic cleaning and battery replacement. The
exterior of the instrument can be cleaned with a dry clean cloth to remove
any oil, grease or grime. Never use liquid solvents or detergents.
Repairs or servicing not covered in this manual should only be performed
by qualified personnel.
4.2 Battery Replacement
WARNING - To avoid electrical shock, disconnect the test leads and
any input signals before replacing the battery. Replace only with the
same type of battery.
This meter is powered by NEDA type 1604 or equivalent 9V battery. When
the meter displays the “ ” symbol, the battery must be replaced to
maintain proper operation. To replace the battery, remove the three screws
from the back of the meter and open the bottom case, remove the battery
from battery compartment and replace it with a new one.
4.3 Fuse Replacement
If no current measurements are possible, check for a blown overload
protection fuse. There are two fuses: F1 for the µA/mA socket and F2 for
the 10A socket. For access to fuses, remove the three screws from the
back of the meter and open the bottom case. Replace F1 only with the
original type 0.5A/250V, fast acting fuse (part no: FUSE500250). Replace
F2 only with the original type 10A/600V, fast acting ceramic fuse (part no:
FUSE10600).
