During this cycle, the weight of the lines being plotted on the display becomes thicker to differentiate
between normal running and ZERO cycle. Dynamic changes in control variables are suspended for the
duration of this event. A letter code
Z representing the event appears on the currently plotted variable.
When completed, the Status Bar returns to its previous state (i.e. Normal Running - PLC Closed [10]).
Diff Bal
Initiate a manual DIFF BAL at any time by selecting this option. The Status Bar displays a DIFF BAL
message (lower left hand corner of the display) that begins counting upwards. In DIFF BAL mode, the
sample air is split and passed through both the reference and analysis sample cells. During the DIFF BAL
cycle, the weight of the lines being plotted on the display becomes thicker to differentiate between normal
running and DIFF BAL cycle. A letter code
DB representing the event appears on the currently plotted
variable. When completed, the Status Bar returns to its previous state (i.e. Normal Running - PLC Closed
[10]).
Measure [Quit]
It terminates a Zero or Diff Bal and returns operation to measure mode. If CIRAS-2 is in the middle of
performing a Zero or Diff Bal during a measurement, it can be terminated by selecting
Measure [Quit].
Initialise
From time to time, a problem may occur that will affect the calibration of the CIRAS-2. Typically, this is
due to an incorrect calibration. In the event that this happens, the system can be reset back to the original
factory default calibration. The calibration factors for each CIRAS-2 analyzer are determined at the factory
and written to an EPROM chip inside the instrument. These factors can be restored with the
Initialise
function, returning the system to its original factory calibration.
Please note: If the system is initialised, CIRAS-
2 will default to “Analyser Only”. Therefore, you will have
to enter Setup - Settings to re-apply your chosen operational and measurement settings.
