>per i pher al uni t s Type of instrument connected (RS232 interface)
The specification of the externally connected instruments is extremely important for the correct functioning of the Liquino in an
automated system. Instead of a printer a computer or other instrument (e.g. a Metrohm titrator) can be connected to the serial
RS232 interface, in order to store Liquino reports or realize complex remote control functions. The is done by selecting the setting
'
send t o: I BM'.
If your type of printer is not listed select 'IBM' or 'Epson'; for laser printers select 'HP'. If your balance is not listed select 'Precisa'.

These settings are only effective in manual operation, i.e. for dosing and dispensing.
In order for the PREP and EMPTY functions to work properly the type of dosing device must be given for each dosing device which
is connected. When the type of dosing unit is specified the corresponding tubing dimensions as defined under 'Configura-
tion>Dosing units' will be used for the internal calculation of the rinsing volume.
