Suitable for

• Troubleshooting electrical circuits in workshops and service calls
• Routine maintenance tasks on electrical equipment and installations
• Educational use in training labs and classroom demonstrations
• Field measurements where a portable, easy-to-read multimeter is needed

Key specifications

• Display resolution: 4200 counts for improved readout detail
• Measurement functions: AC and DC voltage, DC current, resistance
• Form factor: compact handheld housing for portability
• User interface: rotary selector and plain text/segment display for quick selection and reading

How to use

Set the rotary selector to the required function and range before connecting the test leads. For voltage measurements use the parallel connection across the circuit points; for current measurements open the circuit and place the meter in series. Observe polarity when measuring DC values and ensure the range selected exceeds the expected value to avoid overrange. When measuring resistance, disconnect power from the circuit to prevent damage and inaccurate readings.

Usage recommendations

Use appropriately rated test leads and observe safety precautions for the category of measurement. Calibrate or verify the meter periodically against a reference standard if used in professional diagnostics. Store the instrument in a dry environment and replace batteries and test leads as needed to maintain reliable operation.
