11. Quality Evaluation and Replacement of Sensor/Pressure
The sensor/pressure is used in watches equipped with altimeters, barometers and depth meters, and
is a device that measures air pressure.
Since the sensor itself has a certain degree of variation in accuracy, trimming is required with the
sensor/pressure connected to the module in order to ensure that the accuracy of the watch remains
constant.
Malfunctions involving the sensor/pressure include inaccuracy of sensor measured values, FULL dis-
play and Sensor Errors.
When any of these malfunctions occur, however, replacement is usually performed with a module with
sensor (on which trimming has been performed at the Casio factory).
However, when a Sensor/pressure trimming jig set is available, repairs can be performed by replacing
the individual sensor or adjusting the sensor. (Fig. 11-1)
