SAFETY INFORMATION
The following safety information must be observed to
ensure maximum personal safety during the operation of
this meter:
Use the meter only as specified in this manual or the
protection provided by the meter might be impaired.Test
the meter on a known voltage before using it to
determine if hazardous voltages are present.
Do not use the meter if the meter or test leads look
damaged, or if you suspect that the meter is not
operating properly. Never ground yourself when taking
electrical measurements.
Do not touch exposed metal pipes,outlets, fixtures, etc.,
which might be at ground potential. Keep your body
isolated from ground by using dry clothing, rubber shoes,
rubber mats, or any approved insulating material. Turn off
power to the circuit under test before cutting,
unsoldering, or breaking the circuit. Small amounts of
current can be dangerous. Use caution when working
above 60V DC or 30V AC rms. Such voltages pose a
shock hazard.
When using the probes, keep your fingers behind the
finger guards.
Measuring voltage which exceeds the limits of the
multimeter may damage the meter and expose the
operator to a shock hazard. Always observe the meter
voltage limits as stated on the front of the meter.
