Digital Voltage and Continuity Tester

Instruction Manual

Safety Information

• Never use the tester if it or test leads appear damaged.

• Never apply more than 600V DC or 600V AC rms. between any terminal and

earth ground

• When using the probes, keep your fingers behind the finger guard on

the probes.

• Turn off power to the circuit under test before cutting, desoldering, or

breaking the circuit. Small amounts of current can be dangerous.

• Use caution when working with voltage above 60V dc or 30V ac rms. Such

voltages pose a shock hazard.

Automatic Operation

The tester automatically turns on when you short the two test probes or place the

probes across a complete circuit.When turned on, the tester powers up in continuity

mode. If a dc or ac voltage greater than about 4.0V is present across the inputs, the

tester switches to dc or ac voltage mode.The tester automatically shuts down after

approx. 4 minutes of inactivity.

Continuity testing

Turn off circuit power before testing. Beeper indicates shorts lasting 1 ms or longer.
