Amprobe VPC-20 Voltage-Continuity-Tester - Manual

Digital Voltage and Continuity Tester
Model VPC-20
Instruction Manual
m 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.
