MAINTENANCE AND REPAIR

CAUTION
�
To avoid 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 battery
or equivalent

Trouble Shooting

If the instrument fails to operate, check battery, leads, etc., and replace
as necessary. Double check operating procedure as described in this user's
manual. 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.

Cleaning and Storage

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.

Battery Replacement

1. Remove test leads and turn the Meter OFF.
2. Loosen the screw from the battery access door of the case. Lift the
battery access door and thus the battery compartment up.
3. Replace the battery (9V alkaline battery NEDA1604A, JIS6AM6 or
IEC6LF22).
4. Put the battery access door back and re-fasten the screw.
