SAFETY INFORMATION
The following safety information must be observed to insure
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 440VAC or
600VAC industrial power mains. The unit is intended for
use with low energy circuits to 1000VDC or 750VAC or high
energy circuits to 250VAC 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 60VDC or 30VAC 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.
