It works properly.

Type-C Portable Inductance Tester for Electronic Fault Detection

The product is as shown in the picture.

It arrived in good condition, I'll try it tonight.

Thanks to the seller. Delivery in 16 days!!! A good tool for quickly checking the functionality of voltage stabilizers based on throttles. You attach it to the throttle and immediately see whether the voltage stabilizer is working or not. The photo shows how it is attached to the throttle and that the stabilizer is working, which means the green LED on this device is lit.
