SAFETY INFORMATION

The following safety information must be observed to insure maximum

personal safety during the operation at 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 600V AC/DC or high energy
circuit to 250 VAC or DC.

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

4. When using the probes, keep your fingers behind the finger guards on the
probes.

5. Measuring voltage which exceeds the limits of the meter may cause damage
and expose the operator to a shock hazard. Always respect the voltage limits
as stated on the meter.

6. If the equipment is used in a manner not specified by the manufacturer, the
protection provided by the equipment may be impaired.
