As it is not need for current operations, it is offered for sale. It was just test to full output, 80 KV. Data taken for meter, reference output against our standard ( NIST calibrated HVD-200 divider). We offer for sale, separately the POSITIVE and NEGATIVE supplies, which otherwise are identical.These dividers are remotely programmable with 0 to 6 volt signal. The reference output is 0 to 10 volts full scale. Each unit is supplied with a special high voltage cable which has to be wiggled into place and locked in. These units are very stable, though when I used it for precision purposes, I calibrated it monthly against a standard. I will supply calibration report with unit. Positive unit gets original of instruction manual. Negative unit gets a copy. I also have a spare high frequency transformer which I will give if some one buys both units.
The digital volt meters show the output of the reference divider, 75 KV and the reference voltage output 0.89 v so you can see its working. You get my cal report. Greenwich Instrument Co Inc  is an accredited calibration lab to ISO 17025.
