Introduction

 

 

 

the sensor. The diverter, packaged separately when shipped, is necessary when the tee adapter is used to sample gas flowing through a tube.

The diverter is not necessary and should not be used when the sensor is placed directly in a chamber, or when the sensor is used in confined volume analysis, such as incubators and inhalation tents.

CAUTION: THE R17MED SENSOR CONTIANS A CAUSTIC ELECTROLYTE AND LEAD. DO NOT TRY TO OPEN THE SENSOR ASSEMBLY. CHECK THE SENSOR REGULARLY FOR LEAKS. IF THE SENSOR IS LEAKING, REPLACE IT. DO NOT TRY TO REPAIR IT. CONTACT TELEDYNE FOR THE MATERIAL SAFETY DATA SHEET RELATED TO HANDLING AND DISPOSAL.

CAUTION: REMOVE AND SAVE THE DIVERTER WHEN THE SENSOR IS USED IN CONFINED VOLUME APPLICATIONS.

1.5.2 Signal Processing

The electrical voltage developed in the sensor is sent to the electronics. Processing includes amplification, conversion to digits, and comparison to alarm set points if appropriate. Using a microprocessor allows for easier setting of alarms, automatic calibration, and self-diagnosis.

The oxygen level is calculated and then displayed on the liquid crystal display (LCD) on the front panel.

The audio alarm is triggered during a sensor disconnect alarm condition. Pressing the ALARM SILENCE key () will provide an audible alarm override.
