4. Setup
Battery Installation:
The ANENG AN101 Multimeter requires one CR2032 button cell battery (not included). Follow these steps to install the battery:

- Remove the Transparent Case: Using a cross screwdriver, unscrew the screws on the back of the multimeter to detach the transparent case.
- Install CR2032 Button Battery: Carefully place the CR2032 button battery into its compartment, ensuring the positive (+) and negative (-) poles are correctly oriented as indicated.
- Secure the Battery Cover: Reattach the transparent case and tighten the screws with the cross screwdriver.
5. Operating Instructions
To operate the multimeter, select the desired function using the function turntable and connect the test leads appropriately.
General Measurement Steps:
- Insert the black test lead into the 'COM' (common) socket and the red test lead into the appropriate input socket for the measurement type (e.g., VΩHz for voltage, resistance, frequency; mA for current).
- Turn the function turntable to the desired measurement mode.
- Touch the test probes to the circuit or component being measured.
- Read the value on the LCD.
Specific Measurement Modes:

- DC Voltage Measurement (V-): Select 'V-' on the turntable. Connect the red probe to the positive side and the black probe to the negative side of the DC source.
- AC Voltage Measurement (V~): Select 'V~' on the turntable. Connect the probes across the AC source.
- Resistance Measurement (Ω): Select 'Ω' on the turntable. Ensure the circuit is de-energized. Connect the probes across the component to measure its resistance.
- Buzzer Detection (Continuity): Select the continuity mode (often indicated by a speaker icon). Touch the probes to both ends of a wire or component. A continuous beep indicates continuity (a closed circuit). No beep indicates an open circuit.
- Non-Contact Voltage (NCV) Measurement: Turn the turntable to 'NCV' mode. Bring the top of the multimeter close to an AC voltage source. If voltage is detected, the screen will display '----' and an alarm buzzer will sound. The stronger the induced voltage, the more frequent the buzzer.
- Data Hold (HOLD): Press the 'HOLD' button to freeze the current reading on the display. Press it again to release.

- Test Leads: Inspect test leads for any damage (cracks, frayed insulation) before each use. Replace damaged leads immediately.
- Case Integrity: Do not operate the multimeter if its case is damaged or open.
8. Troubleshooting
- No Display/Power: Check if the battery is correctly installed and has sufficient charge. Replace the CR2032 battery if necessary. Ensure the function turntable is not in the 'OFF' position.
- Inaccurate Readings: Ensure the test leads are properly connected and making good contact with the circuit. Check the battery level; low battery can affect accuracy. Verify the correct measurement mode and range are selected.
- No Continuity Beep: Ensure the multimeter is in continuity mode. Check if the circuit or wire being tested is actually continuous.
- Inductance Measurement: The ANENG AN101 is primarily designed for voltage, current, resistance, capacitance, and frequency measurements. While some multimeters can measure inductance, this model's specifications do not explicitly list a dedicated inductance measurement range or function.
- Overload Protection: Information regarding an incorporated overload fuse is not available in the provided product details. Always operate within the specified ranges to prevent damage.
