Diode & Rectifier Testers

CDT Series - Diode and Rectifier Testers: CDT-65AThe CDT-65A is a microprocessor based diode tester designed to provide rebuilders with quick, accurate and easy to use device to check and measure all main parameters of regular and avalanche rectifiers. During the test the measured values are compared with preset limits and GOOD/BAD indication displayed along with an audible beep if the diode is OK.

The readings can be taken even with the stator attached to the rectifier. The tester can detect the direction of the diode and automatically reverse the test probes to provide proper measurement. The limits are fully programmable by the operator.
