Calibration Gas 1, 2 & 3:
These boxes are greyed out in this version and
the data is for information purposes only. If you want to change the current
calibration gas then follow the procedure given in section 8.7.
14)
Calibration Constant A B & C:
These boxes contain the calibration
constants that the Rapidox calculates automatically when you perform a
calibration. You will see that they change each time you perform a new
calibration. Generally the air value should be approximately -10mV and a
low ppm value (e.g. 10ppm) would be approximately 180mV

Analogue Output (0V/4mA & 10V/20mA):
Use these two boxes to set
the High and Low oxygen values for the analogue outputs (6) on the rear
panel. For example if you want 4mA to represent 1% and 20mA to
represent 21% then enter these two values into the appropriate boxes. The
value can be entered either in % or ppm depending on the units selected.
The default is %. The default values are 25% for the high setting and
0.001% for the low setting.
16)
Auxiliary Analogue Output (0V/4mA & 10V/20mA):
Use these two boxes
to set the High and Low auxiliary (pressure sensor) values for the analogue
outputs (6) on the rear panel. For example if you want 0V/4mA to represent
0mbar and 10V/20mA to represent 100mbar then enter these two values
into the appropriate boxes. The units are fixed in mbar.

Absolute Ambient Pressure:
