Used, as is, HP 34401A Multimeter with power cord and test leads. The unit starts up but does not measure. I have included a schematic I downloaded online and did some troubleshooting. It COULD be either but no guarantees [U201 (8-pin op amp) APN: 1826-2420, MPN AD706JR] or [U402 (8-pin op amp) APN: 1826-1991, MPN: AD711JR]. I never ordered the op amps and tried them but apparently, the op amps are available.
The specs in this listing were added by eBay and they appear to be accurate. To verify unit specs, just look up the model online.
