The SR1-1M is a used Resistance Standard from ESI. 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 ESI SR1-1M Standard Resistor is a 1 megohm model of the SR1 family. SR1 resistors are designed to be accurate, stable working standards. The SR1 features binding posts on the top and removable banana plugs on the bottom. The SR1 features a unifiliar winding on a flat mica card to minimize both series inductance and shunt capacitance. These connections facilitate 2-wire or 4-wire use. A durable aluminum case provides electrostatic shielding.
