6.2. Specific Measurement Functions

  • AC/DC Voltage (V~ / V=): The multimeter automatically recognizes or manually adjusts to the voltage gear. Connect the test leads across the component or circuit to measure voltage.
  • Resistance (Ω): The multimeter automatically recognizes or manually adjusts to the resistance gear. Connect the test leads across the resistor to measure its value.
  • Capacitance (┫┣): Adjust to the capacitor gear. Connect both ends of the capacitor with a stylus. Ensure the capacitor is discharged before measurement for safety.
  • Diode (→|): Adjust to the diode gear. Touch the positive and negative electrodes of the Light Emitting Diode with the test leads to check its functionality.
  • On-off Beep (🔊): The multimeter automatically recognizes or manually adjusts to the on-off beep gear. A green light indicates the fuse line is unobstructed.
  • Temperature (°C/°F): Connect the temperature probe (temperature line) to the appropriate inputs. Adjust to the °C/°F gear to measure temperature.
  • Hz Hertz (Hz): Adjust to the Hz gear to measure frequency and duty cycle.
  • NCV (Non-Contact Voltage Detection): Adjust to NCV gear. When the NCV sensing area (11) is close to an AC voltage, the meter buzzer will alarm and the screen will display 'L' or 'H'. The LED indicator light will turn on green or red.
  • Live Line Detection (Live): Adjust to the LIVE file. Plug the red test lead into the power terminal to detect the zero wire. If the meter does not respond, the screen shows 'LIVE'. Plug the red test lead into the power terminal to detect the live wire. The indicator light is on red, and the screen displays '-H'.

6.3. Current Measurement (AC/DC)

WARNING: Current measurements require careful attention to avoid damaging the instrument or causing injury.

  1. Ensure the circuit is de-energized before connecting the multimeter.
  2. Adjust the multimeter to the appropriate current gear (mA or A).
  3. Connect the red test lead to the mA/A current input socket (10) and the black test lead to the COM socket (9).
  4. Crucially, connect the multimeter IN SERIES with the circuit you intend to measure. This means breaking the circuit and inserting the multimeter so that the current flows through it.
  5. Once connected in series, re-energize the circuit and read the current value on the display.

DO NOT directly contact the test leads to a voltage source (like an outlet) when measuring current. This is a common mistake that will damage the multimeter.

9. Troubleshooting

If you encounter issues with your ANENG 626 Multitester, refer to the following common problems and solutions:

  • Device does not power on: Ensure the battery is charged. Connect the USB charging cable and check if the LED indicator lights up.
  • No reading or incorrect reading:
    • Check if the test leads are properly connected to the correct input jacks.
    • Verify that the measurement function is correctly selected (AUTO or specific mode).
    • Ensure the test leads are making good contact with the circuit or component.
    • For current measurements, confirm the multimeter is connected in series.
  • '0L' or '-0L' displayed: This indicates an overrange condition. The measured value exceeds the current range of the multimeter. Select a higher range if available, or ensure the measurement is within the device's capabilities.
  • Multimeter burned out during current measurement: This typically occurs if the multimeter was connected in parallel (like measuring voltage) while in current mode. This is usually due to a blown fuse. Contact support for repair or replacement.
  • Automatic shutdown occurs too frequently: The device is designed to shut down after 15 minutes of inactivity. If it shuts down during active use, ensure the battery is sufficiently charged.

If the problem persists, please contact ANENG customer service for further assistance.
