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
Trouble Shooting
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
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.
