MAINTENANCE
Battery Replacement
Power is supplied by a 9 volt "transistor" battery. (NEDA 1604 IEC 6F22). The
"
" appears on the LCD display when replacement is needed. To replace the
battery, remove the two screws from the back of the meter and lift off the
battery case. Remove the battery from battery contacts.
Fuse Replacement
If no current measurements are possible, check for a blown overload protec-
tion fuse. There are two fuses; F1 for the "mA" jack and F2 for the "10A" jack.
For access to fuses, remove the two screws from the back of the meter and
lift off the battery case. Replace F1 only with the original type 0.5A/250V, fast
acting fuse. Replace F2 only with the original type 10A/600V, fast acting
ceramic fuse.
Cleaning
Periodically wipe the case with a damp cloth and detergent, do not use
abrasives or solvents.
WARNING
Remove test leads before changing battery or fuse
or performing any servicing.
