SAFETY INFORMATION
The following safety information must be
observed to ensure maximum personal safety
during the operation of this meter.
Do not use if 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 before cutting,
desoldering, 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 fingers behind
the finger guards.
Measuring voltage which exceeds the limits
of the multimeter may cause damage to the
meter and expose the operator to a shock
hazard. Always be aware of the meter voltage
limits as stated on the front of the meter.
