Initial Setup
Charging the Multimeter
The ANENG 682 Multimeter comes with a built-in rechargeable lithium-ion battery. To charge the device:
- Locate the Type-C charging port on the side of the multimeter. It is protected by a rubber cover.
- Carefully open the rubber cover to expose the charging port.
- Connect the provided Type-C charging cable to the multimeter's port.
- Plug the other end of the charging cable into a suitable USB power adapter (not included) or a USB port.
- The flashlight port will flash red to indicate that the device is charging. Once fully charged, the light may change or turn off.

Operating Instructions
The ANENG 682 Multimeter features a "Smart Mode" that automatically identifies the measurement type and selects the appropriate range. For specific functions, you can manually switch modes.
Power On/Off
To power on the multimeter, long press the power button located on the left side of the device. The screen will illuminate and display "Auto". To power off, long press the power button again. The device will automatically enter sleep mode if no test instructions are given for a period of time.
DC Voltage Measurement
In Smart Mode, the multimeter can automatically detect and measure DC voltage. Connect the red test lead to the "VΩHz" input jack and the black test lead to the "COM" input jack. Touch the probes to the positive and negative terminals of the DC source (e.g., battery). The display will show the DC voltage reading.
Figure 4: Measuring DC voltage of various batteries.
AC Voltage Measurement
In Smart Mode, the multimeter can automatically detect and measure AC voltage. Connect the red test lead to the "VΩHz" input jack and the black test lead to the "COM" input jack. Insert the probes into the AC outlet or connect to the AC source. The display will show the AC voltage and frequency readings.

Diode Testing
To measure diodes, press the "SEL" button to cycle through modes until the diode symbol appears on the screen. Connect the red test lead to the "VΩHz" input jack and the black test lead to the "COM" input jack. Align the positive and negative poles of the diode with the respective probes. The display will show the forward voltage drop.
Resistance Measurement
In Smart Mode, the multimeter can automatically detect and measure resistance. Connect the red test lead to the "VΩHz" input jack and the black test lead to the "COM" input jack. Touch the probes to the two ends of the resistor. The display will show the resistance value. There is no need to correspond to positive and negative poles for resistance measurement.

Continuity Test
In Smart Mode, the multimeter can automatically detect continuity. Connect the red test lead to the "VΩHz" input jack and the black test lead to the "COM" input jack. Touch the probes to the two points you want to test for continuity. If there is continuity (low resistance), the multimeter will emit an audible buzzer sound.
Non-Contact Voltage (NCV) Detection
The NCV function allows for voltage detection without direct contact. Press the "SEL" button to switch to NCV mode (indicated by "EF" on the screen). Move the top of the multimeter near an AC voltage source. The device will emit an alarm sound and the frequency of the alarm will increase as you get closer to the voltage source, indicating stronger electric field presence.

Live Wire Recognition
To identify live (fire) and neutral (zero) wires, switch to "Live" mode using the "SEL" button. Insert the red test lead into the "VΩHz" input jack. Touch the red probe to the wire. A fast alarm frequency indicates a live wire, while no alarm indicates a neutral wire.

Temperature Measurement
To measure temperature, connect the provided temperature line (thermocouple) to the appropriate input jacks (usually "VΩHz" and "COM" or dedicated temperature ports if available). Press the "SEL" button to switch to temperature mode. Place the thermocouple tip on the object whose temperature you wish to measure. The display will show the temperature in Celsius or Fahrenheit.

Frequency Measurement
In Smart Mode, the multimeter can measure frequency. Connect the red test lead to the "VΩHz" input jack and the black test lead to the "COM" input jack. Apply the probes to the circuit where you want to measure frequency. The display will show the frequency in Hz.
Capacitance Measurement
To measure capacitance, press the "SEL" button to switch to capacitance mode. Important: Before measuring, ensure the capacitor is fully discharged by short-circuiting its terminals to avoid damage to the multimeter. Connect the red test lead to the "VΩHz" input jack and the black test lead to the "COM" input jack. Touch the probes to the capacitor terminals. The display will show the capacitance value.

Current Measurement (AC/DC)
To measure current, you must insert the red test lead into the appropriate current input hole ("mA A" for milliamperes/amperes or "10A/10SEC MAX" for higher currents) and the black test lead into the "COM" input jack. Press the "SEL" button to select AC or DC current measurement. Connect the multimeter in series with the circuit you wish to measure. The display will show the current reading.

Maintenance
- Cleaning: Use a soft, damp cloth to clean the multimeter's surface. Do not use abrasive cleaners or solvents.
- Storage: Store the multimeter in its provided storage bag in a cool, dry place away from direct sunlight and extreme temperatures.
- Battery Care: To prolong battery life, charge the multimeter regularly, even if not in frequent use. Avoid fully discharging the battery for extended periods.
- Test Leads: Inspect test leads for any damage (cracks, frayed wires) before each use. Replace damaged leads immediately to ensure safety and accurate readings.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Multimeter does not power on. | Low battery or fully discharged battery. | Charge the multimeter using the provided Type-C cable. |
| Inaccurate readings. | Damaged test leads, incorrect mode selection, or external interference. | Check test leads for damage and replace if necessary. Ensure correct measurement mode is selected. Avoid strong electromagnetic fields. |
| "OL" (Overload) displayed. | Measurement range exceeded or open circuit. | Ensure the measurement is within the device's specified range. Check for open circuits in continuity or resistance tests. |
| No NCV detection. | Not in NCV mode or voltage is too low. | Switch to NCV mode. Ensure the voltage source is active and strong enough for detection. |
| Screen is dim or unreadable. | Low battery or poor lighting conditions. | Charge the battery. Utilize the built-in backlight feature by pressing the appropriate button. |
