5) MAINTENANCE
To avoide electrical shock, disconnect the meter from any circuit,
remove the test leads from the input jacks and turn OFF the meter
before opening the case. Do not operate with open case. Install
only the same type of fuse or equivalent.
WARNING
Periodically wipe the case with a damp cloth and mild
detergent; do not use abrasives or solvents. If the meter is
not to be used for periods of longer than 60 days, remove the
battery and store it separately.
Cleaning and Storage
If the instrument fails to operate, check battery, fuses, leads, etc.,
And replace as necessary. Double check operating procedure as
described in this user’s manual.
Trouble Shooting
If the instrument voltage-resistance input terminal has subjected
to high voltage transient (caused by lightning or switching surge
to the system) by accident or abnormal conditions of operation,
the series fusible resistors will be blown off (become high
impedance) like fuses to protect the user and the instrument.
Most measuring functions through this terminal will then be open
circuit. The series fusible resistors and the spark gaps should
then be replaced by qualified technician. Refer to the LIMITED
WARRANTY section for obtaining warranty or repairing service.

Battery and Fuse replacement
Battery use :
Single 9V battery.
Fuse use :
Fuse (Fs1) for
m
AmA current input : 1A/600Vac,
IR 100kA, F fuse;
Fuse (Fs2) for A current input : 11A/1000Vac & Vdc,
IR 20kA, F fuse
Battery replacement :
Loosen the 2 screws from the battery access door of the case
bottom. Lift the battery access door and thus the battery
compartment up. Replace the battery. Re-fasten the screws.
Fuse replacement :
Loosen the 4 screws from the case bottom. Lift the end of the case
bottom nearest the input jacks until it unsnaps from the case top.
Replace the blown fuse(s). Replace the case bottom, and ensure
that all the gaskets are properly seated and the two snaps on the
case top (near the LCD side) are engaged. Re -fasten the screws.
