FAQs

How do I measure voltage?

Select the voltage function (V) on the touchscreen. Insert the probes into the correct input jacks. Place the red probe on the positive (+) terminal and the black probe on the negative (-) terminal or common (COM).

How do I measure current?

Select the current function (A) on the touchscreen. Insert the probes into the correct input jacks, often labeled mA or A. You must break the circuit and insert the multimeter in series with the load.

How do I perform a continuity test?

Select the continuity function (often a diode symbol). Place the probes on either end of the component or wire. If there is continuity, the multimeter will beep.

What is the NCVD feature?

NCVD (Non-Contact Voltage Detection) allows you to detect the presence of AC voltage without making direct contact with the circuit. Place the tip of the probe near the suspected wire.

How do I measure resistance?

Select the resistance function (Ω) on the touchscreen. Ensure the circuit is de-energized. Place the probes across the component you want to measure.

What is the data hold function?

The data hold function freezes the current reading on the display. Press the data hold button to activate it, allowing you to view the reading after removing the probes.

What type of USB cable does it use?

The multimeter uses a Type-C USB charging cable.

What safety rating does this multimeter have?

The Sealey MM03 has a CATIII 600V safety rating.

Troubleshooting

Multimeter not turning on.

Ensure the device is charged. Check the power button and charging port.

Inaccurate readings.

Verify the probes are securely connected and the correct function is selected. Check for any damage to the probes.

Continuity test not working.

Ensure the circuit is not live, and the resistance is within the multimeter's range. Check the probes and connections.

Display is dim or unreadable.

Charge the multimeter. Adjust the display brightness setting.
