• if the sensor is disconnected and reconnected
to the instrument
Recommended practice of calibration is against
room air (defined as oxygen concentration of 20.8%).
When a more precise measurement is desired,
repeat calibration using 100% oxygen concentration.
Changes in pressure, humidity or temperature may
affect calibration accuracy (See Appendix B, Effects
of Pressure, Humidity, and Temperature).
Do not handle the sensor unnecessarily
during calibration or use. Body heat can
cause the sensor's thermistor to change
disproportionately to the change in gas
sample temperature at the sensing electrode.
This can produce some error until thermal
equilibrium is restored.
To Calibrate In Room Air (Figure 3-1):
1. Expose sensor to room air.
2. Press I/0 to turn ON the instrument.
• "CAL" flashes in the display.
3. Press 21%. The following appears on the
display:
