This item is an excellent condition used Wavetek 7004N NanoScan Volt Maintenance System. Consists of one 7000N control unit and four 7000 voltage reference modules. Performance verified in our lab but not formally calibrated. *There is a placeholder screw in the far right 7000 module now, but we have a replacement screw of the same type on the way.* Batteries have been tested and seem to be in good condition. Comes with 12VDC power supply. All pictures are of the actual unit.
New replacement model is Fluke 734C.
This item comes with a 6 Month (180 day) warranty. Every pre-owned unit we offer goes through meticulous inspection and NIST calibration to guarantee its reliability and durability.

Wavetek 7004N Nanoscan Volt Maintenance System 0.5ppm StabilityFluke 734C
The 7000N Nanoscan Module generates the 10 V System Average Output, 1 V Divided Output and 10 V 4-wire Buffered Output; provides an External Standard Input; and incorporates Scan Control, Voltage Reversal, Null Detector, Status Display, and Optically Isolated RS232 Interface functions. The 10 V System Average Output is derived from the output of any 7000 Reference Modules in the rack that set to their "In Average" mode. Reference Modules contained in an extension rack are not included in the System Average, because the second rack is unlikely to be a permanent feature (for example, it may only be used as a means of importing calibration). The 7000N Nanoscan Module routes 12 V DC power across the backplane to the 7000 Reference Modules or 7000S Scan Modules. Provided that the 7000 Reference Modules selected as "In Average" are successfully operating from their batteries, the 10 V System Average Output is maintained during line supply failures. The 10 V 4-wire Buffered Output is provided to drive loads such as a Kelvin Varley divider. The source resistance of the System Average output is unsuitable for driving such loads. The External Standard Input is intended for connection of an external reference standard for the purposes of either importing or exporting calibration. The module being scanned and compared against the 10 V System Average by the Null Detector can be controlled directly from the 7000N's front panel or remotely via a PC. The measured difference is indicated on the Scan Status display and is also available over the optical RS232 interface. The optical interface ensures isolation between the 7000Series systems and the PC, eliminating interference and noise problems associated with the PC.
