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
ase. c
Trouble Shooting
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.
