Operating Instructions

Turn unit on:

1. Measure with sound alarm

Press the power button. The meter sounds a single beep and the tip is

illuminated green. The tester is now ON and is operational. Test on

known live circuit to verify tester functionality.

2. Measure without sound alarm

Hold down the power button for 3 seconds. The tip is illuminated green

with no beeping sound. The tester is now ON and is operational. Test

on known live circuit to verify tester functionality.

Turn unit off:

Press the power button. The meter sounds a double beep and the tips

green LED turns off. The tester is now OFF and is not operational.

System self-test:

The "power on" Beeper & green LED visually confirms battery sufficiency,

system integrity, and at operation/active mode. Always test on known live

circuits to verify tester functionality prior to use.

Checking for the presence of AC voltage:

Prior to use, test on known live circuits to verify tester functionality. Place

tip of the tester near an AC voltage. If the tester detects voltage, the LED

in the tip of the tester changes colour from green to red and an beeping

sound is generated. The audible sound beeps quicker when the tester tip

is closer to higher voltage.

Low battery indication:

Scenario 1

Power on the tester: The "power on" LED in the tip of the tester changes

from a steady green to a blinking green and a series of beeping sounds is

generated. The tester then turns off. The unit is now OFF and the

batteries need to be replaced. To replace the tester batteries refer to the

maintenance section titled "Battery Replacement."
