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.
