2.2. Modes
765 Dosimat
6
2.1.1 Key <RATE>
The inquiries of this key are identical for all modes.
Expelling and filling rate
This key is accessible live (except in mode DOS), i.e. rate can be
changed during a running function .
↑ ml/min
Expelling rate
Range for digital setting depending on volume of exchange unit:
1 mL 0.001 3.00 mL/min
5 mL 0.005 15.0 mL/min
10 mL 0.010 30.0 mL/min
20 mL 0.020 60.0 mL/min
50 mL 0.050 150.0 mL/min
Key <CLEAR> sets "OFF", i.e.. the rate can be controlled
analogically by means of potentiometer at the Dosimat 765.
If the preset rate is too high to be dosed with the exchange unit
presently mounted, the rate is set automatically to its maximum.
↓ ml/min
Filling or aspirating rate
The data input rules are the same as for the expelling rate.
The filling rate is set to maximum on changing the exchange unit (e.g.
always after no exch. unit! is displayed!).

the dispensed volume (V-DIS) remains displayed.
PIP: PIPetting
Aspirating and subsequent expelling of a stored pipetting volume.
DIL: DILuting
