WARNING
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.
Troubleshooting
If the instrument fails to operate, check batteries and test 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 batteries
and store them separately
Battery replacement
The meter uses standard 1.5V AAA Size (NEDA 24A or IEC LR03) battery X 2
Loosen the 2 captive screws from the battery cover case. Lift the battery cover case. Replace
the batteries. Replace battery cover case. Re-fasten the screws.
