Abstract: A voltage to current converter is provided for use with a current measuring device, said current measuring device being operable to provide an output voltage which is an analogue of a current to be measured. The converter is arranged to provide an output current which is an analogue of the current to be measured. The converter comprises an electronic controller, a switching amplifier and means for measuring the output current as an analogue voltage and providing a measure of said analogue voltage to the electronic controller.
