This normally indicates one of two things: that you are using the wrong cal
gas value compared with the actual gas flowing over the sensor OR the
sensor is getting old and can no longer output the expected signal required
for a healthy calibration.
2) Bad Pressure Reading: The Rapidox software checks to see what the gas
pressure is before allowing the calibration to continue. If the pressure is
outside the range -25mbar to +25mbar (gauge) then the following message
is displayed:
This normally indicates that you are allowing gas from a cylinder set at too
high pressure to enter the analyser. Try displaying the pressure reading on
the second line of the LCD and adjusting the gas regulator to trim it close to
0 mbar. If you are using a standard gas regulator then try switching off the
sample pump on the rear of the analyser OR better still use a demand flow
regulator and allow the gas to enter the analyser from the draw of the
pump.
3) Faulty Pressure Sensor: If the pressure sensor is faulty or giving
unexpected signals then if you attempt to calibrate the oxygen sensor whilst
in AUTO pressure correction mode you will get a fault message and the
Rapidox will refuse to continue with the calibration:
Please contact Cambridge Sensotec for advice. If you need to use the
analyser in the meantime please disable the pressure correction function
(see section 6.12) and you can continue to calibrate and take readings.
Note that 1) & 2) above are only advisories and you can proceed with the
calibration if you believe everything is checked and correct.
