ABSTRACT:
A measuring device comprises not only a fluctuation-suppressing means between the input and output circuits for absorbing sudden variations in input signal but also a selection control means which can, if so desired, invalidate the fluctuation-suppressing function by the open-close operation on a switch outside the circuits so that the input signal can be transmitted directly to the output side. This reduces the time required for inspection and diagnostic testing and, if the processing functions used in common are incorporated internally, the same circuits can be used both for measurements requiring the fluctuation-suppressing function and for those not requiring it.
