2.1 Keypad
765 Dosimat
5
Rules for data input:
• On entering a negative number, key in minus sign first; <-> is not a "change of sign"
key!
• Changeover between first functions (blank, factor etc.) and digits is done
automatically.
• Terminate parameter entries with <ENTER>.
• Some keys are organized as inquiry drums, i.e. pressing these keys several times, dis-
play shows new inquiries. A new value is stored or a new feature is selected with
<ENTER>. The program then returns to the initial state, the inquiry drum is left. Enter-
ing an inquiry drum, that inquiry, where the drum has been left last time, is displayed
first.
• The Dosimat works with a resolution of 10'000 pulses per burette cylinder volume.
Exchange unit
Resolution of display
Volume/mL Rate mL/min
Smallest increment
V
1 mL .001 .001 0.1 µL
5 mL .001 .005 0.5 µL
10 mL .001 .010 1 µL
20 mL .002 .020 2 µL
50 mL .005 .050 5 µL
If a volume value is entered which can not be dosed exactly with the exchange unit on
the Dosimat, the value is rounded off to the next possible one and stored accordingly.
The smallest possible increments for 1 and 5 mL cylinders are not displayed. However,
they are dosed and the display is rounded.
• Key <CLEAR> sets parameters to "OFF".
