The CVT-7A is a microprocessor based voltage regulator tester. The unit can automatically test with PASS & FAIL indication all types of solid state voltage regulators 12 & 24 Volts. For precise regulator testing, alternator's signals and car's connection are fully simulated. CVT-7A can verify assorted special functions on the regulator, such as SSD, LRC, computer control, etc. The tester can simulate energizing of the alternator for TOS comparison.
