The 721A is a used Standard from Fluke. 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.
- Resolution of Resistance Compensation: 0.1 milliohm
- Maximum Ratio between Divider Resistances: 4000 to 1
- Maximum Allowable Lead Resistance: 150 milliohms
- Maximum Divider Voltage: 150 Volts, DC or peak AC
The Fluke 721A Lead Compensator is a device designed to compensate for the effects of lead and contact resistance in coltage-divider measurement circuits. It is particularly useful in those situations demanding the utmost in accuracy. It is a useful operational accessory for such high-accuracy voltage dividers as the 720A and 725A. The 721A eliminates errors due to contact and lead resistance.
