ABSTRACT:
An electronic measuring system is described. It comprises a switch having a plurality of selectable inputs, the switch being controlled by a controller to select which of the plurality of inputs is fed to an output of the switch. The measuring system optionally includes a verification means to verify operation of the system. The verification means typically forms one or more inputs to the switch. In certain embodiments, the verification means comprises one or more fixed resistors. The output of the system is typically monitored when the or each resistor forms a part thereof. The output of the system is typically compared against previous outputs to determine if there is any change in the output. Any change in the output can be indicative of errors or other problems in the system.
