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.
