Multimeter BLOW 5007# (model UT58D) — handheld digital multimeter for voltage, current, resistance measurement

The BLOW 5007# (model UT58D) is a handheld digital multimeter designed for measuring DC and AC voltage, current and resistance. Its compact format and clearly labelled controls provide straightforward operation for basic diagnostics and troubleshooting of electrical circuits and components. The meter is intended for use in home, workshop and field environments where portable, quick measurements are required.

Advantages

The instrument offers a simple interface with a clear display and a rotary selector for selecting measurement modes. It supports both DC and AC voltage and current measurements as well as resistance checks, enabling basic component testing and fault localization. The compact housing and lightweight construction make the device convenient to carry and use in tight spaces. Built-in input protection and clear measurement ranges reduce the risk of misuse during routine tasks.

Suitable for

• Electrical troubleshooting in household installations
• Basic maintenance and diagnostics in workshops
• Field measurements for technicians and service personnel
• Testing resistors, fuses and simple components
• DIY projects and hobby electronics

Key specifications

• Measurement functions: DC voltage, AC voltage, DC current, AC current, resistance
• Display type: digital numeric display with measurement indicators
• Control: rotary selector for mode and range selection
• Power supply: battery-powered for portable operation
• Form factor: handheld, compact and lightweight housing
• Safety features: basic input protection and fused current input

How to use

Switch the rotary selector to the required measurement function and range before connecting the test leads. Connect the black lead to the common terminal and the red lead to the appropriate input terminal for voltage, current or resistance. For voltage and resistance measurements, place the probes across the component or circuit points to be tested. For current measurement, ensure the correct current input is used and that the meter is placed in series with the circuit. Observe the display and read the value when the reading stabilizes. Turn the meter off after use and remove the test leads when changing measurement modes.

Usage recommendations

Use appropriate personal protective equipment and verify that connections are de-energized when measuring resistance. When measuring current, select the correct range and input to avoid blowing internal protection. Store the meter in a dry, dust-free place and replace the battery when low-battery indication appears to ensure reliable operation.
