Teledyne AX300-I manual Use, Procedure

Operation AX300-I

1.Remove the batteries and remove the five screws that hold the case together.

2.Remove the rear case section leaving the PCB in the front half of the case.

3.Remove jumper at position JP3 and reinstall it at position JP7.

4.Replace the rear cover and secure in place with five screws. Install the batteries and recalibrate per Section 2.1.3.

CAUTION: RECORDER/RS232 OUTPUT SIGNAL SHOULD ONLY BE CONNECTED TO AN EN60601-1/IEC60606-1

APPROVED DEVICE.

To reconfigure the analyzer from a digital (RS 232) output to analog (0-1 VDC) output, use the same procedure except in step 3 remove the jumper from JP7 and replace it at JP3.

2.2 Use

2.2.1 Procedure

Note: Prior to use, always test the batteries. Also check calibration, the sensor for leaks and damage, and the alarm settings.

The AX300-I instrument can be used to measure a gas mixture for oxygen in two basic modes:

•In the inhalation side of breathing circuit ahead of antibacterial filters, humidifiers and medicating devices or other instances where gases are flowing to a patient in breathing circuits.

•In confined volumes such as incubators or tents.

When analyzing for oxygen in breathing circuits, the flow diverter must be used. The diverter should be screwed onto the threaded front end of the R17MED sensor. A tee adapter (plastic, P/N A268, or metal, P/N A283) should be placed into the circuit, and the above sensor assembly plugged into the tee adapter. See Figure 2-3.

CAUTION: CHECK THE BREATHING CIRCUIT FOR LEAKS. BE CERTAIN THAT THE CIRCUIT DOWNSTREAM OF THE SENSOR DOES NOT PRODUCE ANY
