How to use

Before use, verify the battery is installed and the meter is in good condition. Select the required measurement mode with the rotary selector and connect the test leads to the appropriate terminals. For voltage measurements, place the probes across the circuit points with the correct polarity for DC or across the source for AC measurements. For current measurements, break the circuit and place the meter in series or use the appropriate current input if available. For resistance and continuity checks, disconnect power from the circuit and apply the probes across the component or trace. Read the value on the display and switch the meter off when finished to conserve battery life.

Usage recommendations

Use appropriate personal protective equipment when measuring live circuits and follow standard electrical safety practices. Confirm the correct measurement range before connecting to an unknown circuit. For resistance and continuity tests, ensure the circuit is de-energized. Store the multimeter in a dry, dust-free place and replace batteries as needed to maintain accurate readings.
