5.1 పవర్ ఆన్/ఆఫ్

• Press the power button (usually marked with a power symbol) to turn the device on.
• Press and hold the power button to turn the device off. The device will also automatically power off after 5 minutes of inactivity.

5.2 నాన్-కాంటాక్ట్ AC వాల్యూమ్tagఇ డిటెక్షన్ (NCV)

1. పరికరాన్ని ఆన్ చేయండి.
2. Bring the tip of the detector close to the wire, outlet, or electrical component you wish to test.
3. AC వాల్యూమ్ అయితేtage is detected, the device will emit an audible beep and the LED indicator lights will illuminate, with more lights indicating higher voltagఇ బలం.

5.3 సున్నితత్వం సర్దుబాటు

• The device has two sensitivity modes:
  • High Sensitivity (12V~1000V): Suitable for detecting lower voltages or for more precise detection.
  • Low Sensitivity (48V~1000V): Ideal for general detection and reducing false positives from ambient electrical fields.
• Press the sensitivity switch button (often labeled "SENS" or with a sensitivity icon) to toggle between high and low sensitivity modes. The current mode may be indicated by an LED or on the display.

5.4 Zero/Fire Wire Distinction

1. Place the tip of the test pen near the wire or insert it into the socket.
2. The device will indicate the live (fire) wire with a stronger induction signal (e.g., faster beeping, more illuminated LEDs) compared to the neutral (zero) wire.

5.5 LED ఫ్లాష్‌లైట్

• Press the flashlight button (often marked with a light bulb icon) to turn the LED flashlight on or off. This is useful for working in dark environments.
