Hiberation Mode - ION ARA Series Instrument User Manual

At this point click the calibration cap onto the sensor inlet port then open the valve on the manual fixed flow
regulator. The screen on the ARA will then display C90 and begin counting down C89, C88 etc for
approximately 20 seconds for the Oxygen ARA and 90 seconds for the other versions.
NOTE: If its position is moved away from the IR Link after C90 countdown starts, the ARA will continue to
calibrate but the IR software will not acknowledge a pass or fail calibration. Ideally, the ARA needs to be
aligned with the IR Link during the complete calibration procedure.
NOTE: If no gas is connected within approximately 45 seconds, the calibration procedure will fail and display
the below message.
Hibernation Mode*
This option is only for hibernation models (CO & H2S). These models can be powered down (hibernated) to
suspend the operation and extend operational life. Hibernation models display 24 months upon activation
from new. This period remains in place until the ARA has exceeded 12 months of accumulated hibernation.
ION Science cannot guarantee the product after the warranty of 3 years.
To switch over to the hibernation mode, please follow the instructions below:
1) Position the ARA in front of the IR Link
2) Click on the hibernation button, the detector will then go into hibernation.
To differentiate the different models, the hibernation option models have two colored lines on the label
whereas normal models have one thicker line. (See front cover for normal model image)
