SAFETY INFORMATION
The following safety information must be observed to ensure maximum personal
safety during the operation at 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
voltage is 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 on the
probes.
Measuring voltage which exceeds the limits of the multimeter may damage the
meter and expose the operator to a shock hazard. Always recognize the meter
voltage limits as stated on the front of the meter.
