Multimeter BLOW 5018# (UT33B+ compatible) — handheld digital multimeter, basic voltage and continuity testing

The BLOW 5018# handheld digital multimeter (UT33B+ compatible) is a compact instrument designed for basic electrical measurements. It measures DC and AC voltage, resistance, and performs continuity testing, making it suitable for quick diagnostic checks in household installations and simple electronic maintenance. The device offers a clear display and straightforward controls for routine troubleshooting tasks.

Advantages

The multimeter provides essential measurement functions in a compact, lightweight housing that is easy to carry and store. Its compatibility with UT33B+ series user expectations ensures familiar operation and a predictable interface. The instrument delivers clear numerical readouts for voltage and resistance, and a reliable continuity indication for fast circuit checks.

Suitable for

• Troubleshooting household electrical circuits and outlets
• Basic maintenance and fault finding in electronic equipment
• Measuring DC and AC voltages in low-voltage systems
• Resistance checks and continuity tests on wires and connectors
• Portable diagnostic checks by technicians and hobbyists

Key specifications

• Functions: DC voltage, AC voltage, resistance, continuity testing
• Display: digital numeric readout for measurement values
• Form factor: handheld, pocketable design for portable use
• Controls: rotary selector and function switches for direct selection
• Power: battery-powered for field use

How to use

Select the required measurement function using the rotary selector, connect the test leads to the appropriate sockets, and place the probes across the component, conductor, or circuit under test. For voltage measurements, ensure the multimeter is set to the correct DC or AC range before measuring and observe polarity for DC measurements. For resistance and continuity checks, disconnect power from the circuit to avoid damage and obtain accurate readings; the continuity function will provide an audible or visual indication when resistance is below the instrument's threshold.

Usage recommendations

Follow basic electrical safety: verify the test environment, use appropriate personal protective equipment when required, and do not exceed the instrument's intended measurement categories. Replace the battery when the display dims or readings become unstable, and store the multimeter in a dry, dust-free place to maintain reliable operation.
