programmed the new values remain in the memory until they are edited again in
the future.
To select and modify the pressure outputs scroll down to menu option 4 “Set
Outputs” and pres ENT four times. Change the low and high range using the same
procedure described above. The permissible range is -1000mbar to +2000mbar.
Note that in the case of oxygen, the voltage (0 to 10V) and current (4 to 20mA)
outputs are locked together, so that these outputs cannot be set independently of
each other. In normal operation therefore, 0V output always corresponds to 4mA
and 10V always corresponds to 20mA output.
During initial warm up of the Rapidox when the display reads the serial number
the output sent to the rear terminal for oxygen will stay at 2mA (1V) which is the
standby signal. If at any stage a sensor becomes disconnected internally, or the
signal exceeds the measurable range for that sensor, then the display will indicate
there is a fault and the outputs will change to 1mA (0.5V) which is the sensor fault
signal. This will recover as soon as the sensor is reconnected and the fault
cleared. Additional current and voltage signals are provided by the analyser to
give an indication of various conditions and these are described in Table 4 below,
together with the status of the alarms during the condition:
