SAFETY INFORMATION
The following safety information must be observed to
ensure maximum personal safety during the Operation of this

damaged, or if you suspect that the meter is not operating
properly
2. This meter is not recommended for high voltage industrial
use; for examnle. not for measurements of 440 VAC or
use with low energy circuits to 1OOOVDC or 750VAC or
highenergy circuit to 250 VAC or DC. Accidental misuse
by connection across a high voltage, high energy power
be very hazardous.
3. Turn off power to the circuit under test before cutting,
unsoldering, or breaking the circuit. Small amounts of
current tan be dangerous.
4. Use caution when working above 6OV dc or 30V ac rms.
Such voltages pose a shock hazard.
