to set a filling time off min. 30 s to max. 999 s. The display will show your modified values. The cursor is lo-
cated below the digit to be changed. As soon as the cursor has reached the last digit to the right, it will
jump back to the first digit to the left if the <

filling time refers to the duration of one complete piston stroke during the drawing in off dosing or titration
solution. This time is increased by the switching times of the valves of approximately 6 s. If you trigger the
filling process with their contents of the cylinder not being fully ejected, "Filling" will be shortened corre-
spondingly.
The <F3> key serves to select the national language or to set the parameters of the RS-232-C interface.
After a waiting time of 15 seconds the burette will automatically switch to the last selected working method
(function), e.g. „Dosing“ = <Mode>:Dos. The selected working method remains stored after the burette is
switched off.

4.4 Rinsing and initial filling
Considering that a max. of 100 ml of dosing or titration solution will be ejected during “Rinsing/Initial filling”,
a vessel with a min. capacity of 100 ml has to be placed under the burette tip.
