PURPOSE:To avoid useless power consumption and the error in diving data in the next time by providing a constitution wherein a measuring mode is automatically switched to a non-measuring when the measuring mode is continued for a specified time and the measured data are transferred into a memory part. CONSTITUTION:In the case of ordinary regular diving, RSFFs 6 and 8 are reset because abnormal event has happened when a diver does not float after the diving time of six hours has elapsed. The measurement with a three-minutes timer 10 and a diving time timer 12 and the driving of a pressure sensor 14 are stopped. The mode is forcibly switched to a clock mode, and power consumption is saved. When the switching to the clock mode is forgotten after the diving work has been finished, a rest time timer 22 wherein counting is started in floating sends a carrier signal to a latch 23 when 60 minutes are counted. The RSFFs 6 and 20 are reset with the signal. The counting with the timers 10, 12 and 22 is stopped. The mode is switched to the clock mode from a bathometer mode wherein power consumption is high forcibly. The driving data at this time are stored in each resistor of the memory of a RAM 13. |
