Multímetro digital Unit UT-58C com visor LCD e seleção automática de escala, modelo UT-58C

The Unit UT-58C is a handheld digital multimeter with an LCD display and auto-ranging functionality. It provides straightforward measurement of common electrical parameters — AC/DC voltage, DC current, resistance and continuity — in a compact, portable form factor suitable for field and workshop use. The meter is designed for technicians, electricians and hobbyists who need a basic, easy-to-read instrument for routine diagnostics and maintenance tasks.

Advantages

The auto-range function simplifies measurements by automatically selecting the appropriate range, reducing user adjustments and the risk of incorrect range selection. A clear LCD display presents readings legibly, while a compact handheld design improves portability and one-handed operation. The device supports basic protective features and straightforward controls to make common electrical tests efficient and repeatable.

Suitable for

• Troubleshooting household and industrial electrical circuits
• Mains voltage and battery voltage checks
• Continuity testing of fuses, wiring and connectors
• Resistance checks on resistors, sensors and passive components
• Routine maintenance and quick field measurements

Key specifications

• Display type: LCD with numeric readout
• Measurement modes: AC/DC voltage, DC current, resistance, continuity
• Range selection: Auto-ranging for simplified operation
• Form factor: Handheld, portable enclosure
• Input terminals: Standard test probe jacks for handheld multimeters

How to use

Switch the meter to the measurement mode required for the task (voltage, current, resistance or continuity). Connect the test probes to the device under test following standard safety procedures: observe correct probe polarity for DC measurements and ensure the circuit is de-energized when measuring resistance or continuity. Allow the meter to stabilize and read the value displayed on the LCD. For AC measurements, keep probes steady and avoid contact with live conductors beyond the probe tips.

Recommendations

Use the auto-range feature to simplify measurement setup. Before measuring current, verify the expected current range to avoid overloading the meter. When working on live circuits, follow appropriate safety procedures and wear protective equipment. Store the meter in a dry, dust-free place and replace the battery as specified by the manufacturer to maintain reliable measurements.
