Portable Oxygen Monitor OPERATING & SERVICE INSTRUCTIONS MX300-I

Introduction MX300-I
Teledyne Analytical Instruments 10
Options for alternate display configuration). An integral battery life
indicator is displayed “on demand” with the MX300-I.
The instrument is powered by three AA alkaline batteries and is
designed to operate for 2000 hours in non-alarm state.
Oxygen analysis is linear across the single range of 0-100% using
Teledyne’s class R17MED oxygen sensor. A unique sensor failure
alarm is incorporated which warns the user if the sensor signal is lost or
low. When this occurs, the √ SENSOR display flashes. The alarm buzzer
can be silenced by pressing the ALARM SILENCE key. If the alarm
condition is not corrected within 115 seconds the alarm buzzer will
reactivate.
The MX300-I unit incorporates a dual concentration alarm with
individual user-defined set points. The set points are displayed on the
lower portion of the LCD display with the low alarm set point appearing
at the lower left and the high alarm appearing on the lower right of the
display. The alarm circuitry provides both an audible and visual alarm.
