2.2. Modes

765 Dosimat

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.

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!).
