Chapter 2: Operating Procedures
High Alarm Setting
To adjust the high alarm setting:
1. Press the LOCK key to unlock the keypad.
2. Press the HIGH SET key. The HIGH icon will start to flash.
3. Use the UP and DOWN arrow keys to set the high alarm to the desired value.
The high alarm value cannot be set closer than 1% from the low alarm value. For example, if the
low alarm is set at 50%, the system will not accept a high alarm setting less than 51%. Setting the
high alarm to 100% turns off or deactivates the high alarm.
4. When the high alarm value is set, press the HIGH SET key again to accept the high alarm setting
and return to normal operation.
Note:
To automatically set the high alarm to 50% without scrolling the display, hold the HIGH
SET key down, and then press the DOWN ARROW key when the HIGH icon is flashing. To
automatically turn off the high alarm or set it to 100%, hold the HIGH SET key down and
then press the UP ARROW key when the HIGH icon is flashing.

Basic Operation

To check the oxygen concentration of a sample gas:
1. Place the sensor probe in the sensor port on the Bird Sentry blender. If using a standard T adapter
in an alternate location, make sure the sensor is mounted in the adapter with the flow diverter
pointing downward. This will prevent moisture from draining into the sensor membrane.
Note:
It is important that a tight fit exists between the probe and the T adapter
2. Initiate flow of the sample gas to the sensor.
3. Using the ON/OFF key, make sure the Bird Sentry blender is in the Power On mode.
4. Allow the oxygen reading to stabilize. This will normally take about 30 seconds or more.

Alarms and Conditions

In the event of either a low-alarm or high-alarm condition, the corresponding LED will begin to flash,
accompanied by the alarm buzzer. Pressing the SILENCE 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 alarm buzzer, the buzzer will start to
sound again.
Note:
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 actual concentration is 0.1% lower
than the high alarm setting.
