1. Introduktion
This manual provides detailed instructions for the safe operation, maintenance, and troubleshooting of your Tolsen Non-Contact AC Voltage Detector, Model 38110. Please read this manual thoroughly before using the device to ensure proper function and safety.
Produkt overview
The Tolsen 38110 is a CE certified non-contact AC voltage detector designed for quick and safe identification of live AC voltage. It is manufactured according to CAT III (1000V) safety standards, making it suitable for a wide range of electrical applications. The device features a standard AC voltage detection range of 12V to 1000V at a frequency of 50-60Hz.
Nøglefunktioner omfatter:
- Audible and visual alarm modes (sound and light flash).
- Integrated white LED probe light for illumination in dark areas.
- Automatic power-off function to conserve battery life.
- Indikator for lavt batteri.
- Non-Contact Voltage (NCV) sensing with automatic selection of 3 sensitivity levels (high, medium, and low).
- Three types of frequency, sound, and LED alarm indications.
2. Sikkerhedsoplysninger
Always adhere to local safety regulations and guidelines when working with electrical systems. This device is designed to assist in detecting AC voltage, but it should not be used as the sole method for determining the presence of voltage. Always verify with a known live source before testing and a known de-energized source after testing.
- ADVARSEL: Risk of electric shock. Do not use if the device appears damaged or is not functioning correctly.
- Forsøg ikke at måle voltage beyond the specified range (1000V AC).
- Ensure batteries are correctly installed and replaced when the low battery indicator appears.
- Hold enheden tør og ren.
- This device is for non-contact detection only. Do not touch live conductors with the probe tip.

- Probe tip: Registrerer AC voltage uden kontakt.
- LED-indikatorer: Visual indication of voltage presence and sensitivity level.
- Power knap: Tænder/slukker for enheden.
- Lommelygteknap: Activates/deactivates the white LED probe light.
- Batterirum: Located at the bottom, for 2x AAA batteries.
4. Opsætning og batteriinstallation
Installation af batteri
- Twist and pull off the battery cap at the bottom of the detector.
- Isæt to (2) 1.5V AAA-batterier, og sørg for korrekt polaritet (+/-).
- Replace the battery cap, twisting it securely until it clicks into place.
The device will automatically perform a self-test upon power-on. If the low battery indicator illuminates, replace the batteries immediately for accurate readings.
5. Betjeningsvejledning
Tænd/sluk
- Tryk på Power knap (usually marked with 'I' or a power symbol) to turn the detector ON.
- The device will emit a short beep and the LED indicators will flash briefly.
- To turn OFF, press and hold the Power knap until the device powers down, or it will automatically shut off after a period of inactivity.
Brug af lommelygten
- Tryk på Lommelygte knap (usually marked with a light bulb symbol) to turn the white LED probe light ON.
- Press the button again to turn the flashlight OFF.
Non-Contact Voltage (NCV) Detektion
- Ensure the detector is powered ON.
- Place the probe tip near the wire, outlet, or electrical component you wish to test.
- The detector will automatically select the appropriate sensitivity level (High, Medium, or Low) based on the detected voltage styrke.
- Hvis AC voltage is detected, the device will emit an audible beep and the LED indicators will flash. The frequency of the beeps and flashes will increase with higher voltage or closer proximity to the source.
- The LED indicators will also show the detected voltage niveau:
- Lav: Indicates a weaker signal or lower voltage.
- Medium: Indicates a moderate signal or voltage.
- Høj: Indicates a strong signal or higher voltage.
Always test the detector on a known live circuit before and after use to confirm its proper operation.

7. Vedligeholdelse
Rensning
Wipe the device with a dry, clean cloth. Do not use abrasive cleaners or solvents. Ensure no moisture enters the device.
Udskiftning af batteri
When the low battery indicator illuminates, replace the batteries as described in the "Setup and Battery Installation" section. Remove batteries if the device will not be used for an extended period to prevent leakage.
Opbevaring
Opbevar detektoren et køligt, tørt sted, væk fra direkte sollys og ekstreme temperaturer.
8. Fejlfinding
| Problem | Mulig årsag | Løsning |
|---|---|---|
| Enheden tænder ikke. | Døde eller forkert installerede batterier. | Udskift batterierne, og sørg for korrekt polaritet. |
| No detection when voltage er til stede. | Low battery; device too far from source; interference. | Replace batteries; move closer to the source; test in a less noisy electrical environment. |
| False positives (detects voltage when none is present). | Strong electromagnetic fields nearby; static electricity. | Move away from strong fields; ensure proper grounding of the circuit being tested. |
| Lommelygten virker ikke. | Low battery; faulty LED. | Replace batteries. If issue persists, contact customer support. |
