Suitable for

• Measuring DC and AC voltage in household and automotive circuits
• Basic current measurements for low-power circuits
• Resistance checks on components, wiring and connectors
• Troubleshooting simple electrical faults and continuity testing
• Routine maintenance and quick field diagnostics

Key specifications

• Handheld digital multimeter form factor with portable size
• Measurement functions: voltage (DC/AC), current, resistance
• Numeric digital display for direct reading of measured values
• Battery-powered operation for field use
• Single-turn rotary selector for range or function selection

How to use

Before use, install the appropriate battery and connect the test leads to the meter terminals according to polarity. Select the required measurement function and range using the rotary selector. For voltage measurements, place the probes across the circuit or component while observing proper safety practices. For current measurements, break the circuit and insert the meter in series or use the dedicated current input if provided. For resistance checks, ensure the circuit is de-energized and measure across the component or section of wiring. Read the numeric value on the display and switch off the meter after testing to conserve battery life.

Usage recommendations

Use insulated test leads rated for the expected voltages and avoid measuring live circuits above the meter's designed limits. Before measuring unknown circuits, confirm the correct measurement function and range to prevent damage. Store the meter in a dry, dust-free place and replace the battery when display dimming or inaccurate readings occur.
