How to use

Turn on the multimeter and set the rotary switch to the required measurement function and appropriate range. Connect the test leads to the meter terminals and touch the probes to the measurement points: red probe to the positive test point and black probe to the reference or ground. For voltage measurements, select DC or AC as needed; for current, ensure the correct terminal and range are used and observe polarity for DC. Use the resistance or continuity function with the circuit de-energized. Observe the display reading and remove the probes after measurement. Replace the battery when the low-battery indicator appears to maintain accurate readings.

Usage recommendations

Use the multimeter on de-energized circuits for resistance and continuity checks. For live voltage or current measurements, follow standard electrical safety practices, use proper personal protective equipment, and ensure test leads and probes are rated for the measured voltages. Store the instrument in a dry environment and remove the battery for long-term storage.
