Duoyi Digital Transistor / Diode Checker / Tester Model DY294

This is a preowned Duoyi Transistor / Diode Checker / Tester Model DY294.

According to the user leaflet:-

DY294 is mainly used for testing the DC parameters of manifold semiconductors such as diode, transistor, controlled silicon and field effect transistor

An interesting piece of electronic testing equipment, in fairly good working condition, with some scuffs and blemishes commensurate with age and use.  I can't attest to its accuracy.
