2. Safety Information
To ensure safe operation and service of the meter, follow these safety precautions:
- Always ensure the meter is in the correct function and range before making measurements.
- Do not exceed the maximum input values specified for each range.
- Never apply voltage to the meter when the rotary switch is set to current, resistance, diode, or continuity functions.
- Exercise extreme caution when working with voltages above 60V DC or 30V AC RMS, as these pose a shock hazard.
- Inspect test leads for damaged insulation or exposed metal before use. Replace if damaged.
- Disconnect power to the circuit and discharge all high-voltage capacitors before measuring resistance, continuity, or diodes.
- Remove test leads from the circuit before changing functions or ranges.
- Do not operate the meter if it appears damaged or if the case is open.
- Replace batteries as soon as the low battery indicator appears to avoid inaccurate readings.

5. Setup
5.1 Battery Installation
The ANENG AN8000 requires two 1.5V AAA batteries (not included). To install:
- Ensure the multimeter is powered off.
- Locate the battery compartment cover on the back of the unit.
- Use a screwdriver to remove the screw securing the cover.
- Insert two AAA batteries, observing the correct polarity (+ and -) as indicated inside the compartment.
- Replace the battery compartment cover and secure it with the screw.
5.2 Connecting Test Leads
Proper connection of test leads is crucial for accurate and safe measurements.
- Insert the black test lead into the 'COM' (Common) jack.
- For most voltage, resistance, capacitance, frequency, and diode measurements, insert the red test lead into the 'VΩHz' jack.
- For current measurements up to 400mA, insert the red test lead into the 'mA' jack.
- For high current measurements up to 10A, insert the red test lead into the '10A' jack.

6. Operating Instructions
6.1 Power On/Off
To power on the multimeter, rotate the function switch from 'OFF' to any desired measurement function. To power off, rotate the switch back to 'OFF'. The meter also features an auto power-off function to conserve battery life after a period of inactivity.
6.2 Function Selection
The rotary switch is used to select the desired measurement function. The AN8000 features auto-ranging for most functions, simplifying operation.
6.3 Making Measurements
Always ensure the test leads are connected to the correct input jacks for the selected function.
- Voltage (AC/DC): Select the 'V∼' (AC) or 'V—' (DC) position. Connect the test leads in parallel with the circuit or component to be measured.
- Current (AC/DC): Select the 'A∼' (AC) or 'A—' (DC) position. For mA, use the 'mA' jack; for 10A, use the '10A' jack. Connect the meter in series with the circuit.
- Resistance (Ω): Select the 'Ω' position. Ensure the circuit is de-energized. Connect the test leads across the component.
- Capacitance (F): Select the 'F' position. Ensure the capacitor is discharged before connecting the leads.
- Frequency (Hz) / Duty Cycle (%): Select the 'Hz%' position. Connect the leads to the signal source.
- Diode Test (→|): Select the '→|' position. Connect the red lead to the anode and the black lead to the cathode of the diode.
- Continuity Test (♫): Select the '♫' position. Connect the leads across the circuit. A continuous beep indicates continuity.

6.4 Special Functions
- HOLD Button: Press to freeze the current reading on the display. Press again to release.
- Backlight Button: Press to turn the display backlight on or off.
- SELECT/REL Button: Used to switch between functions on a single rotary switch position (e.g., AC/DC voltage, Diode/Continuity) or to activate relative measurement mode.
