120 volts 60 cycle AC Current. The leakage test applies a continuously variable peak voltage from 0 to 2,000 volts. The SCR gating test checks gate control characteristics and provides a means of matching SCR,s according to their gate-current characteristics. This test also is monitored by a DC voltmeter and ammeter. Positively identifies SCR,s that are open, shorted, leaking , breaking down, or gating improperly when voltage is applied.
Tests take only seconds to complete.
