How to use

Insert the specified AAA batteries into the battery compartment and ensure correct polarity. Connect the test leads to the corresponding input terminals and set the function selector to the desired measurement type and range if applicable. For voltage measurement, place the probes across the circuit points; for current measurement, connect the meter in series with the load following safe procedures; for resistance, measure with power removed from the circuit. Read the values on the digital display and switch off the instrument when not in use to preserve battery life.

Usage recommendations

Use appropriate personal protective equipment and observe safe working practices when measuring live circuits. Verify battery condition if the display is dim or readings are unstable. Store the multimeter in a dry environment and avoid exposing it to strong mechanical shocks or prolonged moisture.
