Operation

Always test the meter on a known live circuit before taking measurements

Voltage Measurement

1.

Note: The voltage tester will turn on automatically when voltages

higher than 4.5V AC/DC are detected.

2.

Touch the positive (+) and negative (-) test leads to the device or

circuit under test.

3.

If the voltage is higher than 4.5V AC/DC, the voltage level LEDs will

light and display the reading.

4.

For AC voltages, the

LED and the “AC” LED will light in the display.

For DC voltages, the “DC” LED will light and the “+V” or “-V“ LED will

light to indicate polarity.

Note: The measurement time should not exceed 30 seconds. After 30

seconds the meter should be allowed to cool for 10 minutes.

Single Lead AC Voltage Detection

To check for the presence of voltage (between 100V and 600V) using

only the positive test lead (+), touch the lead to the device or circuit

under test. If voltage is present, the

LEDs will light.

Note

: In this mode, the actual voltage is not displayed; only the

presence of voltage is detected.

Low Impedance Voltage Measurement

Due to the lowered internal impedance, capacitive voltage is

suppressed so that the reading shows the actual voltage

applied. This can be used to quickly identify phantom voltages.

1.

Hold the two test tips on the measuring points to be

tested.

2.

Press the two low impedance test buttons

simultaneously.

3.

The Low Impedance LED will light and the applied

voltage will be displayed on the LEDs.

Note

: The maximum duty cycle in this mode is 5 seconds

for voltages up to 250V. Allow 10 minutes between each reading.

Note

: Measuring from hot to ground may trip any GFCI equipped circuits.

Continuity Test

The tester can measure resistance and alert the user if the resistance value is less than

400kΩ.

1.

Before taking a continuity test, make sure that power to the device or circuit under

test is off and that all capacitors are discharged.

2.

Touch the test tips to the device under test.

3.

If the resistance is less than 400kΩ., the tester will sound an audible alert and

the

continuity LED will light.

Flashlight

Press and hold the

button to turn the flashlight on. Release the button to turn the flashlight off.
