3.3 Non-Contact Voltage (NCV) Measurement

This feature allows for detection of AC voltage without direct contact. It's useful for quickly checking for the presence of voltage in wires or outlets.

  1. Long press the 'SEL' button for more than 2 seconds to turn on the meter, displaying "Auto".
  2. Press the 'NCV/Live' button to select NCV measurement, the meter displays "EF".
  3. Bring the meter tip close to the object (approx. 8-15mm). The intensity of the AC voltage is indicated by three grades:
    • Weak electric field: Display shows "-", intermittent beep, LED flashes.
    • Medium electric field: Display shows "--", intermittent beep, LED flashes.
    • Strongest electric field: Display shows "---H", intermittent beep, LED flashes.

Attention:

  • Remove the black probe from the meter when performing NCV measurements.

3.4 Live Wire Detection

This function helps identify live (hot) wires from neutral wires.

  1. Long press the 'SEL' button for more than 2 seconds to turn on the meter, displaying "Auto".
  2. Press the 'NCV/Live' button to select live wire measurement, the meter displays "LIVE".
  3. When the meter tip is connected to a live wire, the buzzer will emit an intermittent sound, the red LED will flash, and the LCD screen will display "----H". If connected to a neutral wire, there will be no sound, and the LCD screen will display "LIVE".

Attention:

  • Remove the black probe from the meter when performing live wire detection.

3.5 DC Voltage Measurement

  1. Long press the 'SEL' button for more than 2 seconds to turn on the meter, displaying "Auto".
  2. Insert the black probe into the pen cap socket.
  3. Connect the meter tip and black probe to the DC power source or load. The polarity of the connected end of the pen tip and the measured value will be displayed.
  4. Press the 'SEL' button to manually switch to DC voltage measurement if not in auto mode.

Attention:

  • When measuring high voltage, do not touch the tip of the pen or the exposed metal part of the probe to avoid electric shock.

3.6 AC Voltage Measurement

  1. Long press the 'SEL' button for more than 2 seconds to turn on the meter, displaying "Auto".
  2. Insert the black probe into the pen cap socket.
  3. Connect the meter tip and black probe to the AC power source or load.
  4. The display will show the AC voltage measurement.
  5. Press the 'SEL' button to manually switch to AC voltage measurement if not in auto mode.

Attention:

  • When measuring high voltage, do not touch the tip of the pen or the exposed metal part of the probe to avoid electric shock.

3.7 Resistance Measurement

  1. Long press the 'SEL' button for more than 2 seconds to turn on the meter, displaying "Auto".
  2. Insert the black probe into the pen cap socket.
  3. Connect the meter tip and black probe to the resistor to be measured.
  4. The display will show the resistance value.

Attention:

  • When checking in-line resistance, all power to the circuit under test must be turned off, and all capacitors must be fully discharged.

3.8 Continuity Test

  1. Long press the 'SEL' button for more than 2 seconds to turn on the meter, displaying "Auto".
  2. Insert the black probe into the pen cap socket.
  3. Connect the meter tip and black probe to two points in the circuit. If the resistance between these points is less than approximately 50 Ω, the built-in buzzer will sound, the red LED indicator will light up, and the display will show the on-resistance value.

Attention:

  • The circuit under test must be de-energized. Testing an energized circuit will lead to incorrect readings.

3.9 Diode Testing

  1. Long press the 'SEL' button for more than 2 seconds to turn on the meter, displaying "Auto".
  2. Short press the 'SEL' button to switch to diode measurement. The meter displays "OL V".
  3. Insert the black probe into the pen cap socket.
  4. Connect the meter tip to the positive terminal of the diode and the black probe to the negative terminal. The meter screen displays the diode's forward conduction voltage drop in "V". If the diode is reverse-connected, it displays "OL".

Attention:

  • Ensure no voltage is applied across the diode during the test.
