MAINTENANCE
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.
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
under test) by accident or abnormal conditions of
operation, the protective impedance components
in series might 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. Refer to the
WARRANTY selection for obtaining warranty or
repairing service.
Accuracy and calibration
Accuracy is specified for a period of one year after
calibration. Periodic calibration at interval of one
year is recommended to maintain meter accuracy.
If self diagnostic massage “C_Er” is being
displayed while powering on, some meter ranges
might be largely out of specifications.
