Häufig gestellte Fragen (FAQ)
What are the main differences between the HT100, HT100S, and ST100?
HT100: This is a classic non-contact AC voltage tester. It indicates voltage presence through a red/green backlight and varying beeper frequencies. It features dual-range sensitivity adjustments.
HT100S: An upgraded version of the HT100. Its standout feature is the LCD display, which shows the signal intensity as a percentage and an analog bar graph, providing a more precise and intuitive reading than simple LED lights.
ST100: The ST100 is more than just a tester; it is a Smart Pen Multimeter. In addition to non-contact voltage detection (NCV), it can measure specific AC/DC voltage values, resistance, capacitance, and frequency. It also includes phase sequence detection and zero/live wire identification.
Wie funktioniert die Funktion „Berührungslose Spannung“ (NCV)?
The NCV feature allows you to detect voltage without touching bare wires. Simply place the probe tip near an outlet, terminal strip, or power cord. If AC voltage is detected, the tip will light up, an alarm will sound, and the screen will display a signal. This makes testing safer and faster.
Was ist „Dual Sensitivity“ und wann sollte ich sie verwenden?
Kaiweets voltage testers (like the HT100/HT100S) typically offer two sensitivity modes:
- Low Sensitivity (48V-1000V): The default mode. Best for testing standard household outlets and power strips to avoid interference from stray signals.
- High Sensitivity (12V-1000V): Activated by pressing the "S" button. Ideal for testing low-voltage systems (like doorbells or thermostats) or detecting wires buried deeper inside walls.
Können diese Tester Gleichspannung messen?
HT100 & HT100S: No. They are designed strictly to detect the presence of AC voltage.
ST100: Yes. Since the ST100 is a multimeter, it can measure specific DC voltage values (e.g., checking car batteries) as well as AC voltage values.
Wie kann ich zwischen stromführenden und neutralen Drähten unterscheiden?
Place the probe near each wire or into each slot of a socket:
- Live Wire: The tester will detect a strong signal. The screen usually turns red, the bar graph gets high, and the beeper sounds rapidly.
- Neutral Wire: The signal will be weak or non-existent. The screen remains green, and the beeper sounds slowly or not at all.
Kann ich diese verwenden, um einen Kabelbruch zu finden?
Yes. You can use the NCV function to trace along a power cord. When the alarm and light indicators suddenly stop or weaken significantly, you have likely found the breakpoint. This is very useful for troubleshooting extension cords or Christmas lights.
Sind Batterien im Lieferumfang enthalten und wie kann ich Strom sparen?
Yes, most models come with the necessary AAA batteries included.
- Low Battery Indicator: A symbol will appear on the screen when the battery voltage drops (usually below 2.5V).
- Auto Power Off: To conserve battery life, the device will automatically turn off after a few minutes of inactivity (no button presses or signal detection).
Are these testers safe to use?
Absolutely. Kaiweets voltage testers are built to international safety standards (such as CAT III 1000V and CAT IV 600V ratings). They utilize double insulation to ensure user protection during electrical testing.
