3. Pressing the Up key will add one to the high alarm setting and subtract one
from the low alarm setting. Pressing the Down key will subtract one from the
high alarm setting and add one to the low alarm setting. In other words, the Up
Arrow widens the alarm band and the down arrow tightens the alarm band. This
feature will not set the alarm levels above 100% or below 18%.
4. Once the desired alarm settings are attained, press the Un-lock key to
save the settings and return to normal operation mode. If 30 seconds elapse
without a key press by the user, the device will automatically save the new
alarm settings and return to normal operation mode.
3.2 Basic Operation
To check the oxygen concentration of a sample gas:
1. Using the ON/OFF key , make sure the unit is in the power on mode and
properly calibrated.
2. Place the external flow diverter in the sample gas stream. When using a
standard "T" adapter, make sure the sensor is mounted in the adapter
with the flow diverter pointing downward. This will prevent moisture from
potentially draining into the sensor membrane.
NOTE: It is important that a tight fit exists between the diverter and the "T" adapter.
3. Initiate flow of the sample gas to the sensor.
3.3 Alarm Conditions and Priorities
In the event of either a low alarm or high alarm condition, the corresponding
LED will begin to flash, accompanied by the audio buzzer. Pressing the SILENT
key will deactivate the buzzer but the LED and the alarm value digits on the
display will continue to flash until the alarm condition has been rectified. If the
alarm condition still exists 120 seconds after silencing the audio buzzer, the
beeper will start to sound again.
A low alarm condition will remain until the actual concentration is 0.1%
higher than the low alarm setting. A high alarm condition will remain until
the the actual concentration is 0.1% lower than the high alarm setting.
To help differentiate the level of severity, the Monitor provides three unique
audible sequences.
