The machine also has a self-check error reporting function. After power-on, the machine immediately performs self-check, greatly facilitating inspection and maintenance. Such as "pick-up voltage", "drop-out voltage", "normally open pick-up time", etc.

Single-Phase Microcomputer Relay Protection Test Instrument is a highly intelligent, multifunctional relay protection calibration device developed by our factory based on the original. This device adopts microcomputer technology, consisting of a microcontroller, logic control unit, AC/DC current and voltage output unit, high-precision data acquisition unit, LCD display, real-time clock, printer, etc. It has high measurement accuracy and good repeatability. The instrument also has the advantages of beautiful appearance, reliable performance, simple operation, and complete functions. It is an ideal testing equipment for calibrating relay protection devices.

The single-phase relay protection tester can test various AC/DC currents, voltages, intermediate signals, and other individual relays as well as complete relay protection panels. It can test the pick-up voltage (current) value, drop-out voltage (current) value, and the pick-up and drop-out times of various contacts (normally open, normally closed, changeover, delayed). Each test is automatically performed three times, the average of the three times is automatically calculated, and the test results can be printed.
