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).
Displaying °F or °C
The temperature units selection switch is located in the battery compartment.
