General Radio 1409L The 1409L is a used Capacitance Standard from General Radio. Engineers
The 1409L is a used Capacitance Standard from General Radio. 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 GenRad 1409 Standard Capacitor series offers highly stable cost-effective capacitance standards with low temperature coefficient, low losses and a wide range of values. Up to 1 µF, the standard capacitors are constructed of fixed mica capacitors of very high stability for use as two- or three-terminal reference or working standards in the laboratory. From 1 µF to 10 µF the units are made of hermetically sealed polystyrene for 10 μF. Above 10 μF the capacitor is hermetically sealed polycarbonate.
Typical capacitors, observed over decades, have shown random fluctuations of less than + 0.01% in measured capacitance with no evidence of systemic drift.
The capacitors are made out of ≤1 µF silvered-mica and foil, spring-held in a heavy metal camp for mechanical stability. The units are selected for low dissipation factor and are stabilized by heat cycling. They are housed in cast aluminum cases, along with silica gel, which provides continuous dessication. These cases are sealed with high-temperature wax. A well is provided in the wall of the case for insertion of a dial-type thermometer. Three jack-top binding posts are provided on the top of the case, and removable banana plugs on the bottom, for convenient parallel connection without error
