Innova 3320 Auto-Ranging DMM F.A.Q.

How do I measure voltage using the Innova 3320 Multimeter?

To measure voltage, turn the rotary switch to the 'V' symbol. Connect the black lead to the COM jack and the red lead to the VΩ jack. Place the probes across the component or circuit where you need to measure voltage.

What is the proper way to check continuity with the Innova 3320?

Set the dial to the continuity test mode (indicated by a sound wave symbol). Connect the test leads to the circuit or wire. A continuous circuit will emit a beep sound.

How can I replace the battery in my Innova 3320 Multimeter?

To replace the battery, remove the protective rubber cover, unscrew the back panel, and replace the old battery with a new 2 AAA batteries. Reassemble the multimeter afterward.

Why does my Innova 3320 display '1' or 'OL'?

The display shows '1' or 'OL' when the measured value exceeds the selected range. Adjust the range setting or switch to auto-ranging mode.

How to test a diode using the Innova 3320?

Turn the dial to the diode test mode (indicated by a diode symbol). Connect the red test lead to the anode and the black lead to the cathode. The display should show a forward voltage drop if the diode is functional.

What should I do if the multimeter is not turning on?

Check if the batteries are correctly installed and have adequate charge. If not, replace the batteries. Ensure the rotary switch is properly set.

How do I measure current with the Innova 3320?

Switch the dial to the current range (A with a line). Insert the black lead into the COM jack and the red lead into the A jack. Open the circuit and connect the leads in series to measure current.

Can the Innova 3320 measure AC current?

No, the Innova 3320 is designed to measure DC current only. For AC current measurement, a different model that supports AC current is necessary.

How do I change the fuse in my Innova 3320?

To change the fuse, open the back cover by removing the screws. Locate the fuse, gently remove it, and replace it with a fuse of the same rating. Reassemble the multimeter.

What is auto-ranging and how does it work on the Innova 3320?

Auto-ranging automatically selects the correct range for the measurement being taken, providing a more straightforward user experience. The Innova 3320 will adjust itself to display the most significant figures.
