Display -> Test -> COMX port is used to test serial data input (concentration and temperature data from a
PR-01-S refractometer) during the ACTIVE MODE of operation (see Ch. 3.3). Whenever concentration or
temperature data are outside their normal ranges the data will be replaced by the appropriate RANGE HIGH,
or LOW limit values and the error counters Concentration and / or Temperature will be incremented. The
contents of the 2 counters can be cleared by using RESET.
NOTE:
Concentration or temperature data are regarded normal when they are within ranges characteristic of the
usual active crystallization procedures (see Ch. 6.2). However, they can be outside their respective normal
ranges for example after dropping the charge or during cleaning of the pans (concentration or temperature
can be too high). This kind of data monitoring is therefore only active when the strike is ACTIVE, too.

Fig. 10.15
CRYST. PARAMETER : It is used in crystal growth calculations. It is automatically calculated
(re-calculated) after completing or modifying configuration.
TIME OF CRYST. (M) : Time measured from seeding till the end of strike (minutes).
AVERAGE SUPERS. : Average supersaturation from seeding till the end of strike.
NOTES:
1. After the first complete strike, TIME OF CRYSTALLIZATION and AVERAGE SUPERSATURATION
data can be used to refine the data given previously to the related questions during configuration.
2. After a mains failure during a strike AVERAGE SUPERSATURATION can not be calculated. N.A.
will be displayed.
Events
Events are categorised as
•
non-acknowledged,
•
acknowledged and
•
history
types. All three have their dedicated screens with exact date and time data, instrument identification number
(1 / or 2 /), name of the signal and event type (RANGE EXCURSION, HIGH / LOW ALARM). Acknowledged
events are cleared from the list of non-acknowledged ones. The Events History list contains all events until
they fill available memory, when the oldest events will be overwritten with the most recent ones.
