5.3 Measurement Modes (Peak/Real-time)
Прибор предлагает два режима измерения:
- Пиковый режим: Captures and displays the maximum magnetic field strength detected. Press the ПИК button once to enter this mode.
- Режим реального времени: Monitors and displays instantaneous changes in magnetic field strength. Press the ПИК button again to switch to this mode.

5.4 One-Touch Zero Setting
To ensure accurate measurements, perform a zero setting before use. Simply press the НОЛЬ button to reset the display to 000.00.
5.5 Unit Switching (mT/Gs)
Нажмите ЕДИНИЦА button to easily switch between millitesla (mT) and Gauss (Gs) units. (1 mT = 10 Gs).
Figure 5.3: Automatic range switching and unit conversion.
5.6 Automatic Range Switching
The device automatically switches its measurement range. If the magnetic field strength exceeds 200mT, the meter will automatically switch to the 2000mT range to provide accurate readings and prevent overflow errors.
5.7 Automatic N-pole/S-pole Detection
The Tesla Meter can automatically detect and display the polarity of the magnetic field. When the magnetic field passes through the front of the Hall sensor, 'N' (North pole) is displayed. When it passes through the back of the sensor, 'S' (South pole) is displayed.
Figure 5.4: Automatic N-pole/S-pole detection.
5.8 Проведение измерения
Чтобы выполнить измерение:
- Ensure the Hall probe is securely connected and the device is powered on.
- Perform a one-touch zero setting by pressing the НОЛЬ кнопка.
- Place the Hall sensor (tip of the probe) into the magnetic field you wish to measure.
- Wait for the displayed value to stabilize.
- Read the measurement value from the LCD display. The unit and polarity (N/S) will also be shown.
- You can switch between Peak and Real-time modes using the ПИК Нажимайте по мере необходимости.
- You can switch between mT and Gs units using the ЕДИНИЦА кнопка.

If you encounter issues with your Tesla Meter, refer to the following common problems and solutions:
- Устройство не включается:
- Проверьте правильность установки и достаточный заряд батареи 9 В. При необходимости замените.
- Ensure the ON/OFF button is pressed and held for a few seconds.
- Неточные показания:
- Perform a one-touch zero setting by pressing the ZERO button in an area free of magnetic fields.
- Ensure the Hall sensor is positioned correctly relative to the magnetic field (perpendicular for optimal reading).
- Check for any physical damage to the Hall probe.
- Дисплей тусклый или нечитаемый:
- Press the LIGHT button to activate the backlight.
- Проверьте уровень заряда батареи; низкий заряд может повлиять на яркость дисплея.
- Полюс север-юг не обнаружен:
- Ensure the magnetic field is strong enough for detection.
- Verify the Hall sensor is passing through the magnetic field in the correct orientation.
