Setup

1. Battery Installation:

1. Locate the battery compartment cover on the back of the multimeter.
2. Use a screwdriver (if necessary) to open the cover.
3. Insert two 1.5V AAA batteries, observing the correct polarity (+/-).
4. Replace the battery compartment cover and secure it.

2. Connecting Test Leads:

• Insert the black test lead into the "COM" (common) input jack.
• Insert the red test lead into the "VΩHz" input jack for voltage, resistance, capacitance, and frequency measurements.
• Ensure connections are firm before use.

Operating Instructions

To power on the multimeter, press the power button. The device will typically enter auto-ranging mode. Press the "MODE" button to cycle through different measurement functions if manual selection is required.

1. DC/AC Voltage Measurement (V~ / V-):

1. Connect the black test lead to the "COM" terminal and the red test lead to the "VΩHz" terminal.
2. Select the appropriate voltage mode (AC or DC) if not in auto-ranging.
3. Connect the test probes in parallel to the circuit or component you wish to measure.
4. Read the voltage value displayed on the screen.

2. Resistance Measurement (Ω):

1. Ensure the circuit is de-energized and all capacitors are discharged.
2. Connect the test leads as for voltage measurement.
3. Select the resistance mode.
4. Connect the test probes across the component to measure its resistance.

3. Capacitance Measurement:

1. Ensure the capacitor is fully discharged before measurement to prevent damage to the multimeter.
2. Connect the test leads as for voltage measurement.
3. Select the capacitance mode.
4. Connect the test probes across the capacitor terminals.

4. Diode Test:

1. Ensure the diode is disconnected from the circuit.
2. Connect the test leads as for voltage measurement.
3. Select the diode test mode.
4. Connect the red probe to the anode and the black probe to the cathode. A forward voltage drop will be displayed. Reverse the probes; an open circuit (OL) should be displayed.

5. Non-Contact Voltage (NCV) Detection:

1. Press the NCV button to activate NCV mode.
2. Move the tip of the multimeter close to the conductor or outlet.
3. The device will indicate the presence of AC voltage through audible beeps and visual indicators on the screen.

6. Live Wire Detection:

1. Select the LIVE mode.
2. Insert the red probe into the socket or touch the conductor.
3. The multimeter will indicate if the wire is live.

7. Phase Sequence Recognition:

Refer to the on-screen indicators and specific instructions for this function, typically used in three-phase electrical systems to determine the correct phase rotation.

8. Data Hold:

Press the "HOLD" button to freeze the current reading on the display. Press it again to release the hold function.

9. Flashlight:

Press the flashlight button to turn on the integrated flashlight for illuminating dark work areas. Press again to turn off.

Maintenance

Cleaning:

Wipe the multimeter casing with a damp cloth and mild detergent. Do not use abrasives or solvents. Ensure the device is powered off and disconnected from any circuits before cleaning.

Battery Replacement:

Replace the batteries when the low battery indicator appears on the display to maintain measurement accuracy. Refer to the "Setup" section for battery installation instructions.

Probe Tip Replacement:

The probe tip of the multimeter is designed to be replaceable. If the tip becomes damaged or worn, it can be unscrewed and replaced with a new one.
