Why does the OXIGRAF O2iM Monitor calibration drift from the original setting?
The calibration might drift from its original setting because the sensor was not at operating temperature when a 2-point calibration was performed. To resolve this, ensure the unit has fully warmed up and the gas temperature is at 45°C, then recalibrate the device.
What to do if O2 measurement of OXIGRAF O2iM is not close to known gas concentration?
If the oxygen measurement is not close to the known gas concentration, it might be because the calibration was entered with inappropriate calibration gas. To fix this, reset the factory default calibration and then repeat Cal 1.
How to fix OXIGRAF O2iM if the unit will not calibrate?
If the unit won't calibrate, it might be due to the O2 concentration of the low cal gas being too far from the displayed O2 value. You can fix this by resetting the factory default calibration, and then repeating Cal 1.
