This gauge is based on the measurement of thermal conductance and the
indicated value may change depending on the type of the sensor head. Some
sensor heads may require change of the circuitry or structure of the measuring
unit. Therefore, if the type of the sensor head is changed after delivery of the
gauge, re-adjustment will be required. Factory adjusted conditions (type of
sensor head) are inscribed on the measuring unit GP-H. Check them before
operation.
