4. Setup

4.1 Battery Installation

The ANENG Q1 multimeter requires two 1.5V AA batteries (not included). To install or replace batteries:

1. Ensure the multimeter is powered off and disconnect all test leads.
2. Locate the battery compartment cover on the back of the device.
3. Use a screwdriver to loosen the screw securing the cover.
4. Remove the cover and insert two AA batteries, observing correct polarity (+/-).
5. Replace the battery compartment cover and tighten the screw.

4.2 Connecting Test Leads

The multimeter comes with two standard test probes and a 16-in-1 multifunctional test line set. Always connect the black test lead to the COM (Common) jack. Connect the red test lead to the appropriate input jack based on the measurement type:

• VΩHz-+ jack for Voltage, Resistance, Frequency, Diode, and Continuity measurements.
• mA jack for milliampere current measurements.
• μA jack for microampere current measurements.
• 10A MAX jack for high current measurements (up to 10A).

5. Operating Instructions

The ANENG Q1 features both auto-ranging and manual-ranging capabilities. Press the RANGE button to switch between auto and manual modes. In manual mode, press RANGE repeatedly to cycle through available ranges.

5.1 Power On/Off

Press and hold the POWER button (red circle with line) for more than 2 seconds to turn the multimeter on or off. The device also features an Auto Power Off function to conserve battery life.

5.2 Measuring AC/DC Voltage

1. Connect the black test lead to the COM jack and the red test lead to the VΩHz-+ jack.
2. Turn on the multimeter. The device will typically default to auto-ranging voltage measurement.
3. Touch the test probes to the circuit points where voltage is to be measured.
4. Read the voltage value on the display. The multimeter automatically detects AC or DC voltage.

5.3 Measuring AC/DC Current

1. IMPORTANT: Ensure the circuit is de-energized before connecting the multimeter in series.
2. Connect the black test lead to the COM jack. Connect the red test lead to the mA, μA, or 10A MAX jack depending on the expected current.
3. Insert the multimeter in series with the circuit where current is to be measured.
4. Re-energize the circuit.
5. Read the current value on the display.

5.4 Measuring Resistance

1. Connect the black test lead to the COM jack and the red test lead to the VΩHz-+ jack.
2. Ensure the circuit or component is de-energized before measuring resistance.
3. Touch the test probes across the component to be measured.
4. Read the resistance value on the display.

5.5 Measuring Capacitance

1. Connect the black test lead to the COM jack and the red test lead to the VΩHz-+ jack.
2. Ensure the capacitor is fully discharged before measurement to avoid damage to the multimeter.
3. Touch the test probes across the capacitor terminals.
4. Read the capacitance value on the display.

5.6 Measuring Temperature

1. Connect the temperature sensor (thermocouple) to the VΩHz-+ and COM jacks, observing polarity if applicable.
2. Place the tip of the temperature sensor on or near the object whose temperature is to be measured.
3. Read the temperature value on the display. The unit can be switched between Celsius and Fahrenheit.

5.7 Non-Contact Voltage (NCV) Detection

The NCV function allows for detection of AC voltage without direct contact with conductors.

1. Press the NCV button to activate the NCV mode.
2. Move the top of the multimeter near the conductor or outlet.
3. The display will show an increasing number of bars and an audible beep will indicate the presence and strength of AC voltage.

5.8 Diode Test and Continuity

These functions are typically accessed through the VΩHz-+ jack and a dedicated button or range selection.

• Diode Test: Connect the red lead to the anode and the black lead to the cathode of the diode. The display will show the forward voltage drop. Reverse the leads to check for open circuit.
• Continuity Test: Touch the probes to the two points of the circuit. A continuous beep indicates a low resistance path (continuity).

6. Maintenance

6.1 Cleaning

Wipe the case with a damp cloth and mild detergent. Do not use abrasives or solvents. Keep the input terminals free of dirt and moisture.

6.2 Battery Replacement

Refer to Section 4.1 for battery replacement instructions. Replace batteries promptly when the low battery indicator appears on the display.

6.3 Fuse Replacement

The multimeter is protected by internal fuses. If the current measurement function stops working, the fuse may need replacement. Fuse replacement should only be performed by qualified personnel. Refer to the specifications for fuse ratings.

7. Troubleshooting

• No display or faint display: Check battery installation and charge. Replace batteries if necessary.
• Incorrect readings: Ensure test leads are properly connected, the correct function/range is selected, and the batteries are not low.
• Current measurement not working: Check the fuse. If blown, replace with a fuse of the correct rating.
• "OL" or "OVER" on display: Indicates an overload or out-of-range measurement. Select a higher range or ensure the input is within the device's limits.
