Innova MT3320 Auto Ranging Digital Multimeter A practical and reliable digital multimeter for automotive and household electrical measurements, the MT3320 eliminates manual range selection with auto-ranging scales and adds colour-coded LED battery status indication for quick vehicle electrical diagnosis. Product Overview The MT3320 is Innova's auto-ranging digital multimeter, designed for automotive installers, technicians, and DIY users requiring accurate voltage, resistance, and battery condition measurements across both automotive and household electrical systems. Auto-ranging scales automatically select the correct measurement range when a test is made, removing the need to manually dial in the range and reducing the risk of measurement errors from incorrect range selection. A 10 megohm input impedance protects both the meter and the circuit under test from damage caused by loading, making it safe for use on sensitive automotive electronics and household circuits alike. The large digital display provides clear readings in all working conditions, and the single-setting resistance function simplifies the measurement workflow for common installation tasks. Colour-coded LEDs provide a quick visual battery condition check without requiring a separate test procedure. Protective rubber corner guards provide drop protection for workshop and on-vehicle use, and the included attachable test lead holders and stand keep the meter and leads organised and accessible during use. Features & Benefits Auto-Ranging Scales: The auto-ranging function automatically selects the correct measurement range for the input signal being measured, eliminating the need to manually dial in a range before each test. This speeds up the measurement process and prevents incorrect range selection that can produce inaccurate readings or damage the meter. 10 Megohm Input Impedance: The 10 megohm input impedance minimises the loading effect of the meter on the circuit under test, ensuring accurate voltage readings on sensitive automotive electronic circuits and household wiring without drawing significant current from the measured circuit or risking damage to delicate electronics. Colour-Coded LED Battery Quick Check: The colour-coded LED battery status display provides an immediate visual indication of battery condition without requiring a separate measurement procedure, making it a practical quick-check tool for vehicle battery diagnosis during automotive installation and service work. Large Digital Display: The large digital readout provides clear, easy-to-read measurement values in workshop lighting conditions and when working in confined under-dash or engine bay locations. Single-Setting Resistance Function: The resistance measurement function operates from a single setting, simplifying the workflow for common resistance checks performed during installation and fault-finding without requiring multiple dial positions to be navigated. Protective Rubber Corner Guards: The rubber corner guards protect the meter body from impact damage when the meter is placed on work surfaces or accidentally dropped during use, extending the service life of the instrument in workshop environments. Includes Attachable Test Lead Holders and Stand: The included attachable test lead holders keep the test leads organised and attached to the meter when not in use, and the stand allows the meter to be positioned upright on a work surface for hands-free reading during measurements.

It is well suited to checking supply voltage at amplifier terminals, verifying ground connections, measuring speaker impedance, confirming fuse continuity, and performing quick battery condition checks during and after installation. It pairs naturally with Stinger's amplifier wiring kits, circuit breakers, and the full range of F.A.E. amplifier and accessory products where electrical verification is part of the installation process. Frequently Asked Questions What measurements can the MT3320 perform? The MT3320 measures AC voltage, DC voltage, and resistance. It also provides a colour-coded LED battery quick check function for vehicle battery condition assessment. These functions cover the most common measurements needed during automotive audio installation and basic electrical fault-finding. What does auto-ranging mean, and why is it useful? Auto-ranging means the meter automatically selects the appropriate measurement scale for the signal being tested. On a manually ranged multimeter, the user must select the correct range before measuring, and selecting the wrong range produces an error reading or can damage the meter. With auto-ranging, the MT3320 detects the input level and switches to the correct range automatically, making measurements faster and eliminating incorrect range selection errors. What is the 10 megohm input impedance for? Input impedance is the resistance the meter presents to the circuit being measured. A high input impedance of 10 megohms means the meter draws very little current from the circuit under test, which has two important effects: it prevents the meter from loading down sensitive low-current circuits that could give a false reading if current were drawn, and it protects sensitive automotive electronics such as ECU circuits and sensor outputs from damage that could be caused by a low-impedance meter drawing excess current. How does the colour-coded LED battery check work? The colour-coded LEDs provide a visual indication of battery state of charge or condition during a battery quick check measurement. Different LED colours correspond to different voltage ranges, allowing a quick visual assessment of battery condition without reading a specific numerical value. This is particularly useful for a rapid go/no-go battery check during vehicle installation work without setting up a full diagnostic test. Is the MT3320 suitable for use on modern vehicle electronics? Yes. The 10 megohm input impedance makes the MT3320 safe for use on modern vehicle electronic circuits including CAN-bus wiring, sensor circuits, and low-current control signals, where a low-impedance meter could draw enough current to affect circuit behaviour or damage sensitive components.Legendary Products & Support From Authorized Dealers When you choose Frankies BrandBeast, you're choosing quality and performance.
