1. Can test various AC/DC, current, voltage, intermediate, self-holding, and signal relays, as well as entire relay protection panels. It can test the pull-in voltage (current) and release voltage (current) values of various relays, and the pull-in and open-out times of various contacts (normally open, normally closed, changeover, and time-delay). Each test is automatically performed three times and the results are stored. The return coefficient of the three averages is automatically calculated and printed. Test results can be repeatedly displayed and printed.
2. Can easily test various parameters of reclosing relays.
3. Equipped with frequency and phase measurement functions, it can measure the frequency of current and voltage (displaying the time of one cycle, i.e., the period) and the phase difference (time) between two signals.
4. Equipped with two independent channels, both isolated from other outputs of the unit, it can easily measure live contacts, meeting the requirements for online relay testing. Wiring is simple and safe.
5. Employs a precise timing reference (10 microseconds) and a counter with a lifespan of up to 100 hours, so it can be used independently as a precision millisecond timer, replacing a traditional stopwatch.
