The recorder output, accurate to 1% of full scale exclusive of noise and drift, extends the versatility of the instrument.  · Re: Keithley Null Detector - Repair and Restauration attempt. It is like a comparator to a known voltage value with a very high accuracy. The Null Detector can identify very well, when the difference to the known value is ZERO. Or, in other words you can find a precision deviation between a known value and the DUT.  · Keithley Model Null Detector-Microvoltmeter Instruction Manual D. including user manuals, operator's manuals, service manuals, and the like, that (a) have a Tektronix Part Number and (b) are for a measurement product that is no longer supported by Tektronix.

Technical Manuals and Procedures: We are building our Library onto a database so soon will be able to advertise our collection. We have a lot of old Tektronix, Telequipment and Fluke service information. The Calibration procedures have become a sort after section.
