5. Setup

5.1 Battery Installation

1. Unscrew the back cover of the multimeter using the provided Phillips screwdriver.
2. Insert two 1.5V AAA batteries into the battery compartment, ensuring correct polarity.
3. Replace the back cover and secure it with the screw.

5.2 Connecting Accessories

The multimeter comes with a spring test pen line and a spring clip. These can be connected to the COM jack (black pen input/negative) for specific measurements. The positive input/nib probe is integrated into the pen multimeter.

Figure 5: Product parameters and key components, including positive input/nib probe and COM jack.

6. Operating Instructions

6.1 Power On/Off and Backlight

• Power On: Long press the power button () for 2 seconds. The device will enter automatic mode.
• Power Off: Long press the power button for 2 seconds.
• Backlight: Short press the power button to turn the backlight on or off for convenient night reading.

6.2 Automatic Identification Mode

When powered on, the multimeter automatically enters 'Auto' mode, identifying the type of measurement (AC voltage, DC voltage, resistance, continuity) and displaying the reading.

6.3 AC/DC Voltage Measurement

1. Ensure the multimeter is in automatic mode or manually set to the voltage gear.
2. For AC voltage, contact the nib probe and the spring test pen line to both ends of the circuit. The display will show the AC voltage.
3. For DC voltage, contact the nib probe and the spring test pen line to both ends of the battery or DC circuit. The display will show the DC voltage and differentiate between positive and negative poles.

6.4 Continuity (On-Off Beep) and Resistance Measurement

1. Ensure the multimeter is in automatic mode or manually set to the appropriate gear.
2. For continuity, touch the nib probe and the spring test pen line to two points of the circuit. If the resistance is less than 50Ω, the buzzer will sound, and the backlight will turn bright red.
3. For resistance, touch the nib probe and the spring test pen line to both ends of the resistor. The display will show the resistance value.

6.5 Phase Sequence Detection

1. Switch the multimeter to the 'Phase' gear using the SEL button.
2. Touch the nib probe to the A, B, and C point lines of the three-phase electricity sequentially.
3. The screen will display 'PA' then 'PAb' then 'PAbC'. Observe the display to determine if the phase sequence is forward or reverse.

Figure 7: Step-by-step guide for phase sequence detection.

6.6 Live/Naught Line Detection

1. Switch the multimeter to the 'LIVE' gear using the SEL button.
2. Touch the nib probe to the live line. The screen will display '----H' with a beep, and the backlight will turn red.
3. Touch the nib probe to the naught (neutral) line. The screen will display 'Live' without a beep, and the backlight will remain green.

6.7 NCV Voltage Induction

1. Switch the multimeter to the 'NCV' gear using the SEL button.
2. Bring the nib probe close to an AC voltage source.
3. The screen will display 'LO' for low sensitivity or 'HI' for high sensitivity. The green backlight flashes when the induced electric field is weak, and the red backlight flashes and beeps when the induced electric field is strong.

6.8 Line Breakpoint Lookup

In NCV mode, move the nib probe along the wire. Where the alarm sound is strong, the line is smooth and good. The weak signal or absence of signal indicates the position where the line is disconnected (breakpoint).

6.9 Data Hold

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

7. Maintenance

• Cleaning: Wipe the device with a dry, soft cloth. Do not use abrasive cleaners or solvents.
• Battery Replacement: Replace batteries when the low power prompt appears on the screen. Refer to section 5.1 for battery installation steps.
• Storage: Store the multimeter in a cool, dry place away from direct sunlight and extreme temperatures. Remove batteries if storing for extended periods.
• Protective Cover: Use the positive pen cap to prevent tip injuries and protect the probe when not in use.

8. Troubleshooting

• Device not powering on: Check battery installation and ensure batteries are not depleted.
• Inaccurate readings: Ensure probes are making good contact with the circuit. Check for damaged probes or cables.
• No NCV detection: Ensure the device is in NCV mode and the electric field is strong enough to be detected.
• Automatic shutdown too soon: This is a feature to save battery. If you need continuous operation, ensure you are actively using the device or briefly press a button to reset the timer.

10. User Tips

• For automotive circuit measurements, the automatic identification feature can quickly detect AC/DC voltage, resistance, and on-off conditions, making troubleshooting fuses and other components easier.
• Always ensure the pen cap is on the probe when not in use to prevent accidental injury or damage to the tip.
• When performing NCV detection, remember that a stronger electric field will result in more rapid flashing and beeping, indicating closer proximity to the live source.
