Keithley 160 Nixie Digital Multimeter. Laboratory Quality, accuracy within micro volts is possible according to instructions printed on the bottom. Overall appearance is very good. Metal case has minimal signs of age and needs cleaning. Front panel excellent, markings excellent. Original power cord is pretty stiff. Chassis is clean, no rust. At first powerup display was extremely erratic, parts of various numbers missing (see the 11th & 12th pics) . After an hour they were better but still missing some pieces. After 3 hours they were all pretty complete, that's when the lead picture was taken. Pics #13 & 14 show it measuring 2 different DC voltages and comparing pretty close to a Fluke meter so the logic could be basically working. The partial digit displays are possibly the result of HV power supply deficiency. There are undoubtedly other components that will need replacing. Sold as-is for restoration or parts.
