made to the settings. If the batteries have just been installed the LCD will flash 00.0

4.As with most oxygen analyzer(s) the highest level of accuracy is achieved when calibration is conducted using 100% oxygen. After installing the flow diverter as noted in Section 2.1.1, insert the sensor into the plastic tee and connect to a supply of pure dry oxygen flowing at 1-2 liters per minute.

Note: An accessory calibration assembly (P/N C53790) is available from Teledyne for use with the R17MED sensor

5.Wait about 20 seconds to insure the sample line is completely purged with the calibration gas. Press the CAL key. The LCD will count down from 9 to 0. During this time the microprocessor is measuring the sensor output to determine the gas concentration and selects the calibration range i.e. 100% or 20.9%. When the calibration is complete the LCD will display the gas value. Press the LOCK/UNLOCK key to save the calibration data.

Note: The MX300-I can only be calibrated using 100% oxygen or room air 20.9%. Improper calibration or use of other gas concentrations will activate the SENSOR indicator. To repeat the calibration press the LOCK/UNLOCK key and press the CAL key.

6.Remove the sensor from the oxygen supply and confirm the LCD reads less than 22% in room air. It is not necessary for it to read exactly 20.9%.

7.It is important to perform the calibration carefully and thoroughly, using calibration gases that are free from contaminates. Wait for a stable reading before locking in calibration point. The accuracy of the instrument is only as good as the procedure used to calibrate it.

Note: A single point air calibration is not recommended unless the sensor can be exposed to a known source of fresh outdoor air. Hospital room air is often enriched with excess oxygen, which will introduce errors into the calibration. Air calibration should only be used for monitoring oxygen levels between 21% and 40% and
