After pressing a key for the last time, wait at least
for 1 second, then press the grey key once
(3.0 seconds max.), and the displayed volume in
terms of ml will be sent to the printer / computer.
The display remains on the screen, titration can
be continued.
4.8 Dosing
Press the <MODE> key so many times until the
display shows “<MODE>:Dos”.
<Mode>:Dos

ml
Nom. vol. 15.00ml<F2>
Speed: 40.0ml/min<F3>
Dosing: new <Start>
The „Dosing“ function will eject at an exactly definable speed (rate) a nominal volume which is adjust-
able from 0.01 to 999.99 ml. You can set this dosing speed (rate) from 0.5 to 40.0 ml/min in the case of
the TITRONIC
â
â â
â
universal / 20 ml Piston Burette, and to 0.5 to 99.9 ml/min in the case of the
TITRONIC
â â â â
universal / 50 ml Piston Burette. For the 20 ml burette the max. rate is 40 ml/min , for the
50 ml burette it is max. 99.9 ml/min.
You set both the command volume and the dosing rate in a dialogue with the display of the
TITRONIC
â â â â
universal Piston Burette, & „Setting the parameters“ chapter. The stored parameters
remain active even after the burette is switched off.
4.9 Incremental dosing
Use the <MODE> key to select the
„Incremental dosing“ function
You set the parameters in a dialogue with the bu-
rette,
&
„Setting the parameters“ chapter.
<Mode>:Increm.

Increm.: 2.50 ml <F2>
End vol.: 50.00 ml <F3>
Delay : 10.0 s <F5>
Increment new: <Start>
With incremental dosing - Mode>:Increm - you divide an adjustable end volume - End vol.: - into individual,
adjustable volume steps - Increm: -, with a likewise adjustable waiting time - Delay - being inserted between
the individual steps. The addition of the individual volume steps is displayed as total volume.
