MAINTENANCE AND REPAIR

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. Install only the same type of
fuse or equivalent
Calibration
Periodic calibration at intervals of one year is recommended to maintain meter
accuracy. Accuracy is specified for a period of one year after calibration.
If self-diagnostic message "rE-O" is being displayed while powering on, the
meter is re-organizing internal parameters. Do not switch off the meter then,
and it will be back to normal measurement shortly. However, if self-diagnostic
message "C_Er" is being displayed while powering on, some meter ranges
might be largely out of specifications. To avoid mis-leading measurements,
stop using the meter and send it for re-calibration. Refer to the LIMITED
WARRANTY section for obtaining warranty or repairing service.
