The 4035B is a used Resistance Standard from Leeds & Northrup. 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 Leeds & Northrup 4035B, NBS-Type Resistance, standard designed for use as a standard in industrial, research and educational laboratories. Made from selected wire, stress-relieved and aged to assure stability, and constructed so as to permit immersion of the complete unit in oil.
