A current calibration system designed by Guildline Instruments has eliminated thermal EMF effects. The 6622A DCC bridge uses a process of automatic current reversal. The unique architecture of the bridge and its control algorithm further removes gain and offset errors in the Nano-voltmeter balance detector and the precision toroid. The end results are shown by […]
