ABSTRACT:
In a pressure instrument with depth/altitude and time display, a measurement time period from a starting instant up to a stopping instant of the time measurement is measured by measurement-time counting means, and also another measurement data is acquired by detecting pressures from the starting instant up to the stopping instant of the pressure measurement. After the measurements are taken and when a measurement stop signal is outputted, a determination is made whether or not the measured time periods are longer than a predetermined time period. If the measured time period is longer than a predetermined time period, this dive is regarded as one for which it is required to store a record, and then the measurement data acquired between the starting instant and the stopping instant of the measurement are stored in a memory. If, however, the measured time period is shorter than a predetermined time period, this dive is regarded as one for which it is not required to store a record, and then no measurement data is stored. Thus, although the measurement data acquired by SCUBA (self-contained under water breathing apparatus) diving are stored in the memory, the measurement data acquired by non-SCUBA diving with a diving time of 2 to 3 minutes are not stored in this pressure instrument, so that the memory can be more effectively utilized.
