FUNCTION BUTTONS

IR BUTTON 5

Press the IR Button to turn on the infrared thermometer; the Laser

Warning icon D will appear on the LCD (the laser will turn on briefly, DO NOT look directly into the beam). Press and hold the IR button to take temperature readings. Releasing the button will hold the last measurement taken. The thermometer will automatically power-off after approx. 10 seconds of inactivity (held reading will be cleared). The default temperature on power-up is Fahrenheit (°F). To change to Celsius (°C), press and hold the IR and NCV buttons simultaneously. Repeat to return to Fahrenheit (°F).

NCV BUTTON 6

Press the NCV button to turn on the Non-Contact Voltage Tester; the tip will illuminate blue with a single beep. A second short press turns off the Non-Contact Voltage Testing functionality; there will be a double beep and the tip will stop illuminating. The tester will automatically power-off after approx. 5 minutes of inactivity.

By default, the Non-Contact Voltage Tester powers-on in Audible mode. To activate Silent mode, press and hold the NCV button for two seconds; the tip will flash blue to indicate Silent mode has been activated. To return to Audible mode, press and hold the NCV button for two seconds; the tip will flash blue with audible beeping to indicate that Audible mode has been activated.

OPERATING INSTRUCTIONS

CHECKING FOR THE PRESENCE OF AC VOLTAGE

Activate the Non-Contact Voltage Tester as described in FUNCTION BUTTONS.
Test on a known live circuit to verify tester functionality.
Place tip of the tester near AC voltage. If voltage is present the unit will emit audible beeps and a red LED will illuminate:

For low voltage (12V) detection, the red light flashes slowly and beeps are generated.
For high voltage (120V) detection, the red light remains on and continuous beeps are generated.

MEASURING TEMPERATURE

Activate the thermometer and select desired temperature scale as described in FUNCTION BUTTONS.
While holding down the IR button, aim the laser at the object to be measured. The temperature will display on the LCD. The error code "OR" will appear on the LCD if the measurement is outside the thermometer's measurement range.

The targeting laser has a Distance-To-Spot ratio of 4:1, which describes the relationship of the distance between the tester and the object, to the target measurement area. See FIG. 2 for details.

MAINTENANCE

BATTERY REPLACEMENT

When the Low Battery indicator is displayed on the LCD (at 20% remaining battery life), the batteries must be replaced.

Unscrew the battery cap 9 .
Remove and recycle the two spent AAA batteries.
Install two new AAA batteries, with the positive (+) side facing into the tester as shown.
Screw battery cap into place tightly to ensure a tight seal with the O-Ring 8.

SAFETY INSTRUCTIONS

To ensure safe operation and service of the tester, follow these instructions. Failure to observe these warnings can result in severe injury or death.

Risk of electric shock and burn. Contact with live circuits could result in death or serious injury.
Use caution with voltages above 30V AC as a shock hazard may exist.
A single blinking LED or a steady glowing LED and an audible beep indicate voltage present. If no indication, voltage could still be present.
Before and after each use, verify operation by testing a known working circuit that is within the rating of this unit.
Never assume neutral or ground wires are de-energized. Neutrals in multi-wire branch circuits may be energized when disconnected and must be retested before handling.
The tester WILL NOT detect voltage if:
The wire is shielded.
The operator is not grounded or is otherwise isolated from an effective earth ground.
The voltage is DC.
The tester MAY NOT detect voltage if:
The user is not holding the tester.
The user is insulated from the tester with a glove or other materials.
The wire is partially buried or in a grounded metal conduit.
The tester is at a distance from the voltage source.
The field created by the voltage source is being blocked, dampened, or otherwise interfered with.
The frequency of the voltage is not a perfect sine wave between 50 and 500Hz.
The tester is outside of operation conditions (listed in Specifications section).
Operation may be affected by differences in socket design and insulation thickness and type.
Do not use if "power on" LED is not illuminated.
Do not use if tester appears damaged or is not operating properly. If in doubt, replace the tester.
Do not apply more than the rated voltage as marked on the tester (1000V).
Detection above 12V is specified under "normal" conditions as specified below. The tester may detect at a different threshold at different conditions, or may not detect at all unless:
The tip of the tester is within 0.25" of an AC voltage source radiating unimpeded.
The user is holding the body of the tester with his or her bare hand.
The user is standing on or connected to earth ground.
The air humidity is nominal (50% relative humidity – non-condensing).
The tester is held still.
DO NOT direct laser beam into eyes, as this can cause permanent eye damage.
Replace the battery as soon as the low battery indicator appears.
Thermometer is NOT intended for use on people or animals.
Be cautious of readings of reflective materials as the tester may indicate that the surfaces are cooler than the actual temperature.
Avoid using the meter around strong electromagnetic fields.
Always wear approved eye protection.

DO NOT attempt to repair this tester. It contains no serviceable parts.
DO NOT expose tester to extremes in temperature or high humidity.
