SAFETY INFORMATION

The following safety information must be observed to ensure maximum

personal safety during the operation of this meter:

1. Do not use the meter if the meter or test leads look damaged, or if you
suspect that the meter is not operating properly.

2. This meter is not recommended for high voltage industrial use; for example,
not for measurements of 440 VAC or 600 VAC industrial power mains. The
unit is intended for use with low energy circuits to 1000VDC or 750VAC or
high energy circuit to 250 VAC or DC. Accidental misuse by connection
across a high voltage, high energy power source when the meter is set up
for mA measurement may be very hazardous.

3. Turn off power to the circuit under test before cutting, unsoldering, or
breaking the circuit. Small amounts of current can be dangerous.

4. Use caution when working above 60V dc or 30V ac rms. Such voltages pose
a shock hazard.

5. When Using the probes, keep your fingers behind the finger guards on the
probes.

6. 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.

7. If the equipment is used in a manner not specified by the manufacturer, the

protection provided the equipment may be impaired.
