I *think* you meant Fluke 752A, right? I bought mine on the 'bay', for about US$600 IIRC, but I had to wait for the right deal to get that price. These are US$20K+ instruments when new, so this is quite a bargain. Many cal-labs have chucked these in favor of their self-calibrating Fluke 57xx calibrators, which [I think] is a mistake, as the 752A has far better ratio specs for 1000V [0.5ppm] and 100V [0.2ppm] than anything else I can find. For low voltage, the Fluke 720A Kelvin-Varley divider [or an HP/Agilent/Keysight 3458A] wins at 0.1ppm ... ========================================================================
