The Innova 3320 is useful for measuring most ranges that include: AC/DC millivolts and milliamps, AC/DC volts to 600V, resistance and continuity, and DC amps. It also boasts a diode check.

  • Auto-ranging scales.
  • Single-setting resistance function for DC and AC voltage.
  • UL certified product.
  • Protective rubber corner guards.
  • Large digital display and color coded LED’s.

This multimeter will measure 200 mA of AC current and up to 10 amps of DC current. If measuring AC current is an important thing you need to do, we think this meter is not for you. But if measuring current isn’t the common everyday type of measurements, then it is a big deal.

This Innova Multimeter has a battery load tester. You can select one the four common voltages in it, and you will know the status of the battery from the color coded LED’s. The LED’s will display red for bad, orange for weak, and green for good.
