#40 - EDC 520A DC calibrator repair and adjustment

Описание к видео #40 - EDC 520A DC calibrator repair and adjustment

This unit had a blown output stage. After repairing the output amplifier it became apparent that the unit is way out of spec. The adjustment procedure was done, which seemed to bring the instrument back to proper operation.
