The RS925D is a used Resistance Standard from Tegam. 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.
Initial Adjustment Accuracy..± (20PPM + 1m) at any setting
100 to 100k decks individually trimmed to 1 to 2 PPM Accuracy
Stability after adjustment... ± (20PPM + 0.5m) per year
The Tegam Model RS925D is a four-terminal, continuously variable resistance standard. Values from 10m to 1.2M can be achieved using eight decade switches. The rheostat offers a resolution of 20m.
Use of Evanohm, wire-wound precision resistors provide an accurate, stable standard with good temperature characteristics. The Model RS925D can be used as a standalone resistance standard or in conjunction with the Tegam Models 801B/801C, and 240C to complete a 242D or 242E Resistance Measurement System.
