1. Turn off the multimeter by rotating the switch to the 'OFF' position.
2. Locate the battery compartment cover on the back of the device.
3. Use a screwdriver to loosen the screw(s) securing the battery cover.
4. Remove the cover.
5. Insert new batteries, observing the correct polarity (+ and -) as indicated inside the compartment.
6. Replace the battery cover and secure it with the screw(s).

5. Operating Instructions

Before taking any measurements, ensure the test leads are properly connected and the rotary switch is set to the desired function.

5.1. General Measurement Steps

1. Insert the black test lead into the COM jack.
2. Insert the red test lead into the appropriate input jack for the measurement type (e.g., VΩmA).
3. Rotate the function switch to the desired measurement function.
4. Connect the test probes to the circuit or component under test.
5. Read the measurement value on the LCD screen.

5.2. DC Voltage Measurement

To measure DC voltage (e.g., batteries):

1. Set the rotary switch to the 'V=' (DC Voltage) position.
2. Connect the red probe to the positive (+) side of the DC source and the black probe to the negative (-) side.
3. The voltage reading will appear on the display.

5.3. AC Voltage Measurement

To measure AC voltage (e.g., wall outlets):

Image: An illustration depicting the KPS-MT460 multimeter's probes inserted into an AC wall outlet, demonstrating how to measure AC voltage.

1. Set the rotary switch to the 'V~' (AC Voltage) position.
2. Insert the probes into the AC source.
3. The voltage reading will appear on the display.

5.4. Resistance Measurement

To measure resistance:

1. Set the rotary switch to the 'Ω' (Resistance) position.
2. Ensure the circuit is de-energized before measuring resistance.
3. Connect the probes across the component whose resistance you want to measure.
4. The resistance value will be displayed.

5.5. Continuity Test

To test for continuity:

1. Set the rotary switch to the '•)))' (Continuity) position.
2. Ensure the circuit is de-energized.
3. Touch the probes to the two points you want to test.
4. If continuity exists (low resistance), the multimeter will emit an audible beep.

5.6. Non-Contact Voltage (NCV) Detection

The NCV function allows for detecting AC voltage without direct contact.

1. Press the 'NCV' button. The NCV indicator will illuminate.
2. Move the tip of the multimeter close to the conductor or outlet you suspect has AC voltage.
3. If AC voltage is detected, the NCV indicator will flash, and an audible beep will sound, with the frequency increasing as the voltage strength increases.

5.7. Data Hold (HOLD)

To freeze the current reading on the display:

• Press the 'HOLD' button during a measurement. The 'H' symbol will appear.
• Press 'HOLD' again to release the reading and return to live measurement.

5.8. Max Hold (MAX)

To capture the maximum measured value:

• Press the 'MAX' button during a measurement. The 'MAX' symbol will appear.
• The display will show the highest value recorded since the function was activated.
• Press 'MAX' again to exit this mode.

5.9. Auto Power Off (APO)

The multimeter features an Auto Power Off function to conserve battery life. If no operation occurs for a certain period (typically 15 minutes), the device will automatically power off. Press any button or rotate the switch to turn it back on.

6. Maintenance

6.1. Cleaning

• Wipe the case with a damp cloth and mild detergent. Do not use abrasives or solvents.
• Ensure the multimeter is completely dry before use.
