My sample was defective. One of the battery holder's contact has not been soldered. It's good that the device sometimes started, and I was able to fix it. The device has a contrast display. The device allows you to evaluate the form of voltage and current in power devices with low-frequency alternating current (such as UPS, engine-generator, etc.).
