Standards - Capacitance decades

A standard resistor provides a very low value reference (a few micro ohms) or a very high value reference (some tera-ohms), with the highest levels of accuracy. It can be used as a standard for controlling and adjusting devices such as milliohmmeters, microhmmeters or meghommeter / teraohmmeters.
