 Read First
-Avoid working alone so assistance can
be rendered.
- Do not use test leads or the Meter if
they look damaged.
- Do not use the Meter if the Meter is
not operating properly or if it is wet.
- Use the Meter only as specified in the
Instruction card or the protection by
the Meter might be impaired.
- Use extreme caution when working
around bare conductors or bus bar.
Contact with the conductor could
result in electric shock.
- Use caution with voltages above 30 V
ac rms, or 60 V dc. These voltages
pose a shock hazard.
