1.4 Working with several dosing units 

799 GPT Titrino: Getting started

 

 

 

11

 

Manual dosing 

• 

to prepare an Exchange Unit (or Dosing Unit, resp.) 

• 

for quick dosing 

 

If you press the key <DOS>, the dosing unit from the 

method is working. This dosing unit appears in the dis-

play. 

If you wish to dose with another dosing unit, use the key 

<PREP> to select the dosing unit and press <DOS> to 

dose. 

 

<PREP> 

 

 

 

 

 

 

 

<PREP> 

<DOS>, <STOP/FILL> 

 

 

 

 

 

 

 

 

 

 

 

<QUIT> 

 

 

Press <PREP>. In the display appears "inter-

nal D0 prep", i.e. the dosing unit of the Titrino has been 

selected. 

 

Press <PREP> again. In the display appears "exter-

nal D1: prep". 

 

Press the key <DOS> on the Titrino: The external dos-

ing unit D1 doses. If you press the key <STOP/FILL> on 

the Titrino, it will fill again. 

 

With <START>, the function "prep" is started. This pre-

pares the dosing units. (The parameters for "prep" are 

under the key <CONFIG>, in the group ">prep.dosing 

elements"). 

Attention:

 With the function "prep", liquid will be ex-

pelled! 

 

If the dosing unit D1 is a Dosino, you can empty the dos-

ing unit completely (e.g. for cleaning). Choose the func-
tion "empty" with the key <

←

> or <

→

> and start with 

<START>. 

Attention: 

With the function "empty", liquid will be ex-

pelled! 

 

Quit the selection of dosing units with <QUIT>.
