La misurazione può essere eseguita inserendo la sonda nel materiale dopo aver selezionato la funzione appropriata. Dopo aver premuto nuovamente il pulsante “SEL”, è possibile passare alla misurazione della temperatura ambiente ℃, dopodiché è possibile passare alla misurazione della temperatura ambiente ℉ dopo aver premuto nuovamente il pulsante “SEL”.

[48-Month Warranty] We provide 48 months unconditional warranty and lifetime after-sales service.

Tip 1: Why there is no reading: If the wooden board was too dry to register readings, the wood is an insulator at that moment, resulting in a non-conductive between the two pins.

Tip 2: For best wood moisture results, push the pins deep into the material, make sure the pins are in contact with the material (wall, wood or hardwood).

[AC Voltage Detection] AC voltage can be measured and displayed, according to the size of the AC voltage can be distinguished between neutral and live wires and leakage. Working voltage: AC voltage 12-300V (50/60Hz). Note: The Contact Voltage Test Button must be held down with a finger during measurement. Due to the differences in the human body lead to different resistance values, so the measurement data has error, the measurement data is only to determine the neutral and live wires and leakage.

[Non-contact Voltage (NCV) Sense Mode Measurement (12-1000V)] Wide-area search to initially locate the voltage. The Voltage tester emits an audible and visual alarm when it detects a voltage, and the closer the measured voltage is, the stronger the audible and visual alarm becomes.

[Live Wire Mode Measurement (12-300V)] More accurate voltage detection. The voltage tester will not alarm until it is contacted with voltage. When the voltage tester detects voltage, an audible and visual alarm will sound and the screen will display “L”.
