Figure 8.12 a) shows how to set up an output (SUPERSATURATION) channel.
To modify type CHANGE and continue the Set up as shown in Fig. 8.12 b) and Fig. 8.13.
To free an already reserved output channel select item (Fig. 8.12 a)), then select CLEAR and type CHANGE
(Fig. 8.12 b)).
To add a new output select item (for example: DENSITY) and type CHANGE (Fig. 8.12 a)).
Select CHANNEL and type CHANGE (Fig. 8.12 b)). Available free channels will be offered automatically. If
there is no available channel, make one free first.

IMPORTANT NOTE:
Having completed selections or changes during any SET UP operation it is highly recommended to
check if the final settings are really correct (go to SET UP -> ANALOG OUTPUT). Do not forget to
close the operations by pushing the ACCEPT or ENTER key.
9 MANUAL SEEDING
It is highly recommended to practice automatic seeding whenever possible. It will result in reproducible
strikes, which, if the set-point for seeding was selected properly (see: Ch. 2.5) and the process of
crystallization was also controlled well, will provide consequently high-quality product.
Manual seeding can be the selected (though not recommended) mode of seeding. However, in un-common
situations manual seeding of the crystallizer might be necessary. The mode of seeding (MANUAL SEED, or
AUTO SEED) can and should be configured in advance during CONFIGURE -> SEEDING (see: Ch. 7.5).
