A Time electronics DC voltage potentiometer, it all turns on and outputs voltages fine, unfortunately I am not convinced it is as accurate as it says but it may be my digital multimeter.
Spec'ed at 0.02% voltage range 9.999V to 999.99uV
Battery charges up still even although it has been in my shed for many years.
Sold as seen.
