Frequently Asked Questions

?

Why does the backlight dim after about 10 seconds?

The backlight of the multimeter will gradually dim after about 10 seconds, and this function is to save power. Please press and hold the "Hold" button for 2s to activate the backlight.

?

What if the numbers jumping on the multimeter's screen when the test leads are not connected?

The multimeter may be affected by the surrounding magnetic field before the test, so the numbers will jump on the screen when the test leads are not connected. This phenomenon does not affect the use of multimeter.

?

What if the multimeter stops working?

Please remove the screws and take it off, then check if the battery and the two fuses are in good condition. Please contact our support team directly for help if them are in good condition: support@astroai.com.

?

Why can't the multimeter test AC current?

Please note this model cannot AC current, you can consider out other 4000c/6000c multimeter.

Love this. Easy to use. Quickly tests batteries.

This is really easy to use. I appreciate that I can check all my batteries so far. I’ve been using it for about two months and instead of just tossing batteries that I think aren’t working I know for sure if they’re working or not if they’re dead or not so easy to use simple purchase compact design. I can take it with me like if I go camping or somewhere like that and it’s very lightweight so I like it

Built for the user

Absolutely love this multimeter. I've lived my life with cheap $5 harbor freight multimeters, but doing some dumb diagnosing with it I blew the main fuse inside. I've been using this since 2024. I was able to open it up, get the spec of the fuse (5x20mm .250amp) and swapped the 10 amp fuse for the time being while the replacement is shipped next day. The auto off is super convenient, it beeps before it's gonna shut off. and the beeping for continuity check is super nice for probing harnesses and not having vision of the readout on the meter. I added another in my cart for my next purchase as it warrants me having one in each of my workshop locations. the 9v or 2xAAA battery configuration options thing is super convenient. I feel like a paid reviewer but just have been very happy with it and am going through the time to put in a review
