How to use

Insert a fresh 9V alkaline battery into the compartment, connect the test probes to the meter’s input sockets, and select the appropriate measurement function and range. For voltage measurements, set the meter to the correct AC or DC range and place probes across the circuit points; for current, use the correct current range and observe proper series connection if required; for resistance, ensure the circuit is de-energized before measuring. Read the numeric result on the 3.5‑digit display and switch off the meter when finished to conserve battery life.

Usage recommendations

Prioritize safety by checking that the selected range and CAT III 300V rating match the measured circuit. De-energize circuits before resistance checks, inspect test leads for damage, and replace the battery when low to maintain accurate readings. Store the multimeter in a dry, dust‑free place when not in use.
