Automotive & Household Electrical Tool

The AstroAI ASIM4K0R is a new TRMS multimeter with 4000 counts for automotive and household electrical troubleshooting. It suits DIYers and hobbyists who need accurate measurements for home or commercial improvements. The kit includes the meter, a pair of test leads, a user manual and two 1.5V AAA batteries.

TRMS 4000 Counts Auto-Ranging

This meter measures AC/DC voltage to 600V, current to 10A and resistance to 40M. It adds dedicated 1.5V, 9V and 12V battery test modes with red or green indicator lights. Non-contact voltage detection uses sound and light alarms without test leads.

Safety Fused Design & Install Ease

Double ceramic fuses protect against overload and meet overvoltage category III 600V standards. A silicone cover guards the unit from drop damage and electric shock. Install is straightforward: insert the included batteries, select the function and connect leads or use the NCV sensor. Common issues include blown fuses if inputs exceed rated limits and low battery indication when power drops.

Questions about this item

What does the 4000-count display mean for everyday measurements?

The 4000-count display provides higher resolution than lower-count meters, letting you see smaller changes in voltage, current or resistance readings.

What safety standard does the CAT III 600V rating cover in practice?

The CAT III 600V rating means the meter is tested for use on fixed building wiring and distribution panels up to 600 volts.

How large is the unit and will it fit in a standard tool pouch?

The meter measures 14.9 by 7.1 by 3.5 centimetres and weighs 219 grams, so it fits easily in most tool pouches or a shirt pocket.
