The Extech EX310 is a compact multimeter designed for electricians and similar professionals who need reliable voltage testing in a durable package. Its key benefit is the integrated non-contact voltage detection (NCV), allowing for quick and safe checks. A potential caveat is its manual ranging, which requires user input for selecting measurement ranges, unlike auto-ranging models. This device offers 2000 counts, CATIII 600V safety rating, and includes essential functions like AC/DC voltage and current, resistance, diode, continuity, and battery testing.

CATIII 600V is a safety rating that indicates the multimeter is suitable for use in distribution-level electrical environments, such as panel boards and fixed installations, up to 600 Volts.
Select the V~ (AC Voltage) function. Choose an appropriate range (or start with the highest if unsure for manual ranging). Connect the black lead to COM and the red lead to the VΩmA jack. Place the probes across the component or circuit you want to measure.
Turn the dial to the NCV setting. Bring the tip of the multimeter near a conductor. If AC voltage is present, the multimeter will emit an audible beep and/or a visual indicator will light up.
Yes, the EX310 can measure DC current. Select the A- (DC Current) function and plug the red lead into the appropriate current jack (10A for higher currents, or mA for lower currents) and the black lead into COM. You will need to break the circuit and connect the multimeter in series.
The battery test function is specifically designed to test 1.5V and 9V batteries.
The rubber holster is designed to be a permanent protective feature and is not intended for removal.
The EX310 has a resistance measurement capability up to 20 Megaohms (20MΩ).
Check if the battery is installed correctly and has sufficient charge. Replace the battery if necessary.
Ensure the test leads are firmly connected and properly inserted into the correct jacks. Verify that the multimeter is set to the appropriate measurement function and range for the circuit being tested. Check the condition of the test leads for any damage.
Ensure the NCV function is selected and that the tip of the multimeter is brought close to the conductor. The NCV function detects AC voltage; it will not respond to DC voltage or unenergized circuits. Ensure the device has sufficient battery power.
Confirm the multimeter is set to the continuity function and that the circuit being tested is de-energized. A break in the circuit or a resistance value above the threshold will prevent the beep. Ensure test leads are good.
