Powers up fine as seen in last photo, just shows error because there’s no scales hooked up. The back can use a cleaning. Check out my other listings as well. Thank you for looking.

All Magnescale DRO’s read “Error” when no probe is connected. This unit works fine. It was used with a Sony Magnescale DG205P probe. Includes a socket for a Sony Magnescale HA-13 Head Amplifier/translator/interface.
