5. Setup

5.1 Battery Installation

The multimeter requires two 1.5V AAA batteries for operation. If the batteries are not pre-installed or need replacement, follow these steps:

1. Ensure the multimeter is turned OFF.
2. Locate the battery compartment on the back of the meter.
3. Use a screwdriver to open the battery compartment cover.
4. Insert the two AAA batteries, observing the correct polarity (+ and -) as indicated inside the compartment.
5. Replace the battery compartment cover and secure it with the screw.

5.2 Connecting Test Leads

Always connect the test leads correctly for the desired measurement:

• The black test lead (negative) should always be connected to the COM (Common) input jack.
• For most voltage, resistance, capacitance, frequency, diode, and continuity measurements, connect the red test lead (positive) to the VΩmA input jack.
• For current measurements up to 600mA, connect the red test lead to the VΩmA input jack.
• For high current measurements (up to 10A), connect the red test lead to the 10A input jack.

6. Operating Instructions

Turn the rotary switch to the desired function. The meter features auto-ranging for most functions, simplifying operation.

6.1 Measuring AC/DC Voltage (V∼ / V−)

1. Connect the black test lead to the COM jack and the red test lead to the VΩmA jack.
2. Turn the rotary switch to the V∼ (AC Voltage) or V− (DC Voltage) position.
3. Touch the test probes to the circuit points where voltage is to be measured.
4. Read the voltage value on the LCD display.

6.2 Measuring Resistance (Ω)

1. Ensure the circuit is de-energized before measuring resistance.
2. Connect the black test lead to the COM jack and the red test lead to the VΩmA jack.
3. Turn the rotary switch to the Ω (Resistance) position.
4. Touch the test probes across the component or circuit segment to be measured.
5. Read the resistance value on the LCD display.

6.3 Continuity Test

1. Ensure the circuit is de-energized.
2. Connect the black test lead to the COM jack and the red test lead to the VΩmA jack.
3. Turn the rotary switch to the ♫ (Continuity) position.
4. Touch the test probes to the two points of the circuit or component.
5. If continuity exists (low resistance), the meter will emit an audible beep. The display will show a low resistance value.

6.4 Non-Contact Voltage (NCV) Detection

1. Turn the rotary switch to the NCV position.
2. Move the top end of the multimeter near a conductor or outlet.
3. If AC voltage is detected, the meter will beep and the NCV indicator light will illuminate. The frequency of beeps and light flashes increases with stronger voltage.

6.5 Temperature Measurement (°C/°F)

1. Connect the K-type temperature probe to the VΩmA (positive) and COM (negative) input jacks, observing polarity.
2. Turn the rotary switch to the °C/°F position.
3. Place the tip of the temperature probe on or in the object whose temperature is to be measured.
4. Read the temperature value on the LCD display. Use the "SELECT" button to switch between Celsius and Fahrenheit if available.

6.6 Other Functions (Current, Capacitance, Frequency, Diode)

For other measurement functions, connect the test leads as appropriate (refer to section 5.2) and select the corresponding position on the rotary switch. Use the SELECT button to cycle through sub-functions if a single rotary switch position covers multiple measurement types (e.g., AC/DC current, diode/continuity).

• Current (A∼ / A−): Ensure the meter is connected in series with the circuit. Use the 10A jack for high currents.
• Capacitance (F): Ensure capacitors are discharged before testing.
• Frequency (Hz): Connect across the signal source.
• Diode Test: Connect across the diode to measure forward voltage drop.

7. Maintenance

7.1 Cleaning

Wipe the meter casing with a damp cloth and mild detergent. Do not use abrasives or solvents. Keep the input jacks free from dust and debris.

7.2 Battery Replacement

Replace the batteries when the low battery indicator appears on the display. Refer to section 5.1 for detailed instructions.

7.3 Fuse Replacement

If the meter fails to measure current, the fuse may be blown. Fuse replacement should only be performed by qualified personnel. The meter uses double fuses for protection. Refer to the internal diagram for fuse specifications if replacement is necessary.
