Introduction MX300-I

Section 2.1.5.

In addition to the above instrument configuration options, the following optional equipment is available for your instrument:

•Universal Pole Mounting Clamp (P/N CP 2343)

•V-Mount Pole Clamp (P/N CP 2344)

•V-Mount Wall Adapter P/N B 647)

•0-1 VDC Interface Cable (P/NB-75554)

•RS 232 Interface Cable (P/N B-75555)

1.4Applications

The MX300-I Portable oxygen analyzer is intended to continuously measure and display the concentration of oxygen in a gas mixtures used in medical applications such as Anesthesia, Respiratory therapy and is intended for adult, pediatric and Neonatal populations.

The instruments may be used in verifying oxygen concentrations in gas mixtures used in:

•Anesthesia

•Respiratory Therapy

•Neonatal Care

1.5Theory of Operation

The MX300-I monitor can be divided into two major functional groups:

•R17MED Oxygen Sensor

•Signal Processing

The analyzer uses Teledyne Analytical Instruments Patented R17MED oxygen sensor. The millovolt output signal from the sensor is fed into the electronic signal processor, where it is used to calculate the oxygen gas concentration and display it on the LCD screen. The data from the sensor is compared to the alarm values set by the user, and activates the audible and visual alarms if the oxygen level exceeds those values. A unique sensor fail/disconnect alarm is incorporated in the MX300-I to warn the user of a sensor problem. The√ SENSOR indicator
