Compact automotive multimeter

The Audiovox AM33D is a pocket-sized digital multimeter designed for automotive and household electrical troubleshooting. It measures AC and DC voltage, DC current, resistance, diode function and continuity with a 2000-count display. The kit includes a 9 V battery, test leads and a manual, meeting IEC 61010 safety standards. It suits DIYers and technicians who need a basic diagnostic tool for vehicles, fuses, batteries and charging systems.

Build integration and safety features

The meter runs on the included 9 V 6F22 battery and requires no external power supply. A protective silicone cover shields the unit from drops and helps prevent electric shock. Double fuse protection guards against overload during measurements. The backlit LCD and data-hold function free the user to work in dim areas and capture readings without a second pair of hands. Auto power-off conserves battery life between jobs.

Sustained-use behaviour

Sampling runs at two readings per second, giving a steady update rate during extended testing sessions. The 1999-count 3½-digit display maintains polarity indication for both negative and positive values. Low-battery warning appears on screen before voltage drops affect accuracy. Operating range spans 32 °F to 104 °F, so the tool remains reliable during long periods in engine bays or outdoor environments. It cannot measure AC current or AC voltage below 100 mV.

Questions about this item

What is the maximum voltage the AM33D can measure continuously without overload?

The AM33D is rated for a maximum operating voltage of 500 volts, with a double fuse providing anti-burn and overload protection during sustained use.

How much heat does the meter generate during all-day operation and what is its operating temperature range?

The multimeter operates between 32 and 104 degrees Fahrenheit; its low-power, battery-powered design and auto-shutoff feature minimise heat buildup during extended sessions.

Which battery type must I have on hand for the AM33D to work out of the box?

A 9V 6F22 battery is required and is included in the package along with test leads and a user manual.
