A sensor signal processing apparatus for measuring a physical quantity through the use of a sensor. A data processor automatically provides an operation equation by applying two known physical quantities, at two points, to the sensor and storing the data at these two points in a pair of memories. The quantities in the memories are then converted in accordance with a sensor characteristics equation and displayed on a display unit. In addition, a battery is used to supply the data processor with power. If that battery's voltage level falls below a certain point an alarm is sounded, indicating that the battery should be replaced.
