The 2724A is a used Resistance Standard from Valhalla Scientific. Engineers use direct current (DC) voltage standards to calibrate, standardize, normalize, and monitor drift, verify linearity, and establish regulation in electronic equipment. Standards are important during electronics compliance testing. Phase angle standards are ideal for calibrating many different electronics, including power analyzers, vector voltmeters, phase meters, phase sensitive instruments, and resolvers.
The Valhalla Scientific 2724A, Resistance Standard, that provides over 10 million resistance values ranging from 100 micro-ohms to 11 gigohms. The unit accomplishes this feat by using microprocessor technology coupled with an extremely high resolution A/D converter to "synthesize" the programmed value of resistance.
