Water dispensing via volumetric control
Ultrapure water systems which are equipped with the volumetric dispense option can dispense a preset
volume of water.
As soon as the Nonstop-mode is selected, a liter volume is shown in line 3 of the display. This is the
volume of ultrapure water that was last dispensed.
A single press on the Enter-button enables this volume value to be changed within the range from 0.01
to 65.5 liters by means of the arrow-buttons. The UV-button can be used to position the cursor at the
particular digit that you wish to change.
A second press on the Enter-button causes the volume of water that has been set to be dispensed. The
liter volume shown in the display is the actual volume dispensed. Dispensing stops as soon as the set
volume is reached.
Dispensing can be stopped at any time by a further press on the Enter-button. This enables small
volumes to be dispensed by two successive presses on the Enter-button. One press starts dispensing
and, when the wanted amount has been dispensed, a second press stops dispensing. The button on the
dispenser has the same function as the Enter-button.
Volumetric dispense is supported in all versions.
The display shows:
OFF mode
A second press on the ON/Off-button causes the display to go dark and all text output on the display
to be extinguished. No outputs are now switched.
