The Outline

AX-733A is the unit built-in the function to check the VF for LED elements. The measurement current is setup 1.0mA～99.9mA each, indicates the VF value from 0.00V～9.99V.

Also the comparator indicates for panel and outputs the judgment signal of HI (OPEN), GO (SHORT) set up by LO LIMIT and HI LIMIT for the VF value. When LED is reverse polarity, outputs POL signal, and judges the VF measurement to flow the measurement current into the opposite direction at the same time.
