SAFETY INFORMATION

PRESS TO RE-POWER
The following safety information must be
observed to insure maximum personal safety
during the operation of this meter:
1. Do not use 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 haz-
ard. 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 pro-
tection provided by the equipment may
be impaired.
7. Fused test leads in accordance with
H.S.E. guidance note GS38 should be
used in high energy circuits.

OPERATION

Before taking any measurements, read the Safety Information Section.
Always examine the instrument for damage, contamination (excessive
dirt, grease, etc.) and defects. Examine the test leads for cracked or frayed
insulation. If any abnormal conditions exist do not attempt to make any
measurements.
Autoranging
The meter defaults to autorange when you turn it on. In autorange, the
meter selects the range automatically.
