BATTERY INSTALLATION

1. Access the battery compartment by gently pressing the pocket clip release

latch and sliding the cover down.

2. Insert three LR44 button batteries (observe polarity).

3. Replace and latch the cover

NOTE: If your meter does not work properly, check the battery to make sure

that it still good and that it is properly inserted.

You, as the end user, are legally bound (Battery ordinance) to return

all used batteries and accumulators; disposal in the household

garbage is prohibited!

You can hand over your used batteries / accumulators, gratuitously,

at the collection points for our branches in your community or

wherever batteries / accumulators are sold!

Disposal

Follow the valid legal stipulations in respect of the disposal of the

device at the end of its lifecycle

5. NCV detector

6. NCV indicator cone

7. NCV measurement button

8. Battery compartment release latch.

AC VOLTAGE DETECTION

WARNING: Risk of Electrocution. Before use, always test the Voltage Detector

on a known live circuit to verify proper operation

1. PRESS and HOLD the NCV button.

2. The cone tip will light up for approximately 2 seconds and then turn off,

ensuring that the LED is working correctly. Continue holding the NCV button.

3. Place the probe tip near the hot conductor or next to the hot side of the

electrical outlet.

4. If AC voltage is present, the detector cone will produce a steady constant

glow.

NOTE: The conductors in electrical cord sets are often twisted. For best results, rub

the probe tip along a length of the cord to assure placing the tip in close proximity

to the live conductor.

NOTE: The detector is designed with high sensitivity. Static electricity or other

sources of energy will randomly trip the sensor. This is normal operation.

IR TEMPERATURE MEASUREMENTS

NOTE: The IR thermometer has a distance to target ratio of 1:1. For the most

accurate readings position the meter as close as possible to the target..

1. Point the IR sensor toward object to be measured,

2. PRESS and HOLD the IR button.

3. The meter will turn ON, “SCAN” will flash in the display and the measured

surface temperature will appear in the display.

4. Release the MEASURE button, “HOLD” will appear and the last measured

value will remain in the display until the meter turns off (approximately 30

seconds).
