1. Introduzione
The KAIWEETS VT100 is a non-contact AC voltage tester designed for safe and efficient electrical testing. It can detect AC voltage from 50V to 1000V, identify live and null wires, and locate breakpoints in wires. This manual provides essential information for the proper and safe use of your device.
2. Informazioni sulla sicurezza
Always prioritize safety when working with electricity. Read and understand all safety warnings before using this device.
- IEC Rated Safety: This device is IEC rated CAT III 1000V and CAT IV 600V, meeting CE requirements. It is safely double insulated.
- Alto volumetage Avviso: An alert will activate for voltages above 90V, indicated by the screen turning red and a safety symbol illuminating.
- Allarmi acustici e visivi: The tester provides multiple alarms through sound and light. When voltage is detected, the tip emits a red light and beeps. The frequency of beeps increases with higher sensed voltage o più vicino al voltage fonte.
- Funzionamento senza contatto: Designed for non-contact AC voltage detection, minimizing direct exposure to live circuits.
- Dispositivi di protezione individuale: Quando si eseguono lavori elettrici, indossare sempre dispositivi di protezione individuale (DPI) adeguati, come guanti isolanti e occhiali di sicurezza.

- Pulsante di accensione/luce: Controlla l'alimentazione e la funzione torcia.
- Indicatore di alimentazione: Illuminates when the device is on.
- Indicatore di segnale: Flashes to indicate voltage rilevamento.
- Torcia elettrica: Fornisce illuminazione nelle zone buie.
- Sonda (testa del sensore NCV): The tip used for non-contact voltage rilevamento.
4. Impostazione
4.1 Installazione della batteria
- Twist and remove the battery cover at the rear of the tester.
- Inserire due batterie AAA da 1.5 V, assicurandosi della corretta polarità (+/-).
- Richiudere il coperchio della batteria e ruotarlo per fissarlo.
The device includes two AAA batteries for immediate use.
5. Istruzioni per l'uso
5.1 Accensione/spegnimento
Press the Power/Light button to turn the tester on. The power indicator will illuminate. Press and hold the button to turn it off. The device features an automatic power-off function after 5 minutes of inactivity or no signal detection to conserve battery life.
5.2 Senza contatto voltage (NCV) Rilevamento
The VT100 uses an NCV inductive probe to detect AC voltage senza contatto diretto.
- Assicurarsi che il tester sia acceso.
- Place the tip of the tester near a terminal strip, outlet, or supply cord.
- Se voltage is present, the tip will glow red, and the pen will emit an audible beep. The intensity of the light and frequency of the beep indicate the strength of the detected voltage.

5.3 Live/Null Wire Identification
The tester can automatically distinguish between live and neutral (null) wires based on signal strength.
- The live wire will produce stronger signals, resulting in a faster beep rate and brighter red light.
- The null wire will produce weaker or no signals.
5.4 Wire Breakpoint Finder
The VT100 can assist in locating breakpoints in insulated wires.
- Move the tester along the length of the insulated wire.
- Il tester indicherà il volumetage up to the point of the break. The absence of a signal beyond a certain point suggests a breakpoint.

Torcia elettrica 5.5 LED
Press the Power/Light button briefly to toggle the LED flashlight on or off. This feature is useful for working in dimly lit environments.

6. Manutenzione
6.1 Pulizia
Wipe the device with a dry, clean cloth. Do not use abrasive cleaners or solvents that could damage the casing o componenti interni.
6.2 Sostituzione della batteria
When the low-power indicator activates (battery voltage below 2.5V), replace the batteries promptly to ensure accurate readings and proper functionality. Refer to Section 4.1 for battery installation instructions.
6.3 Conservazione
Conservare il tester in un luogo fresco e asciutto, lontano dalla luce solare diretta e da temperature estreme. Se si conserva per periodi prolungati, rimuovere le batterie per evitare perdite.
7. Risoluzione Dei Problemi
- Il dispositivo non si accende: Controllare l'installazione delle batterie e assicurarsi che non siano scariche. Sostituirle se necessario.
- Letture incoerenti: Ensure the probe is clean and free from obstructions. Test in an area with known voltage per verificare la funzionalità.
- Indicatore di basso consumo: If the low-power indicator is active, replace the AAA batteries immediately.
- Spegnimento automatico: The device is designed to power off after 5 minutes of no operation or signal detection. This is normal behavior to save battery.
