  • Page 9: Oxygen Fuel Cell Setup And Calibration Procedure

    Oxygen Cells are chemical batteries and therefore have a limited life span. While O Cells can last longer than 12 months, HydroSpace Engineering, Inc. recommends replacement of the O cell(s) on an annual basis. This will help insure the reliability and accuracy of the O Cell's usage.

  • Page 10: Connecting The O 2 Cell

    10/25/06 Connecting the O Cell The bulkhead receptacle on the HS Explorer and the corresponding cell connector are self aligning. WARNING Never force the connector and do not use tools on the connector. The connector/receptacle may be damaged or loosened on the housing causing a leak. WARNING The connector is NOT designed to be connected/disconnected under water.
  • Page 11 10/25/06 Figure 4 – Calibration Oxygen Percentage • Set the calibration gas percentage of oxygen. Please see the appendix for setting the correct percentage at altitude. • To change the calibration gas percentage, press the LEFT button to decrease the percentage and press the right button to increase the percentage.
  • Page 12 10/25/06 In the event calibration is lost and the unit is active, an “A” will be displayed on the center segment. This requires calibration to clear. Removing the battery is the currently known method for loss of calibration. Figure 6 below shows the monitor in the active mode with a calibration alarm. Figure 6 –...
