CI-90A User’s Manual
Page 14
The labels can be attached to the petri dish holding the just completed sample and/or associated
documentation, the purpose being to reduce any human errors in record keeping. The user can
opt to have 0, 1, 2, or 3 labels printed after the sample. If the CI-90A should run out of paper
during the printing of a label, the user can add more label paper and reprint the particular label.
To select the number of labels to print, the user must first enter the setup menu, if not already
there, and then use the up/down arrows as necessary to scroll to the # LABELS TO PRINT line
(shown below). The user can then select the desired number by using the left/right arrows to
scroll through the available values.
Similarly, to select the number of labels to print when an error occurs, the user must scroll to
the # ERRLBS TO PRINT, and then select the desired number by using the left/right arrows to
scroll through the available values. The same label will be printed, except the Sample Status will
be
INVALID .
2.2.4 Beep on complete?
The CI-90A allows the user to set an audible alert to signal the completion of a sample. If set,
six loud beeps of short duration will occur at the end of a sample so that the user will know the
sample ended. The bright green Sample LED will also flash until the user acknowledges the
sample end by pressing a key.
To select the beep on complete option, the user must first enter the setup menu, if not already
there, and then use the up/down arrows as necessary to scroll to the BEEP ON COMPLETE
field. The user can toggle this option on or off (Y or N) by using the left/right arrows.
2.2.5 Enable flow alarm?
The CI-90A allows the user to set a flow alarm that will detect an out-of-range flow condition.
This guarantees all samples taken to be the correct sample volume within tolerance. The criteria
for activating the flow alarm is a measured flow deviation from nominal of greater than

10%
for three consecutive seconds. The CI-90A’s internal mass flow meter analog output is
conditioned and converted into a digital signal representing the flow value. This digital value is
monitored by the CI-90A’s microprocessor and corrected using the stored flow calibration
values. The flow value is converted and displayed as the flow rate during sampling, and checked
every second for alarm violation. When a flow alarm occurs, the CI-90A will stop sampling and
