Page 11: Operation Overview
3000HR HIGH RESISTANCE STANDARD OPERATION MANUAL Operation Overview Principle of Operation High value resistance measurements above 100MΩ traditionally require careful consideration with regards to noise / interference. The principle of the high resistance standard is to allow measurements to be taken at lower resistance values where a measurement can be achieved with lower noise / interference levels. -
