Before any RF vacuum tube voltmeter is to be calibrated, it should be tested for several weeks to determine how well it may retain its calibration. In this way effort lost in trying to calibrate it to an accuracy beyond its inherent capabilities can be avoided. AT voltmeters, thermal converters and RF micropotentiometers as working standards provide simple, accurate and yet rapid means for calibrating vacuum tube voltmeters.
