Under
‘Extended’
-
‘Curve type’
processing types, you can freely program
the pump behaviour.
There are 3 curve types:
n
‘Linear’
n
‘Lower sideband’
(lower sideband)
n
‘Upper sideband’
(upper sideband)
The following applies to all three curve types:
The smallest processable difference between I1 and I2 is 4
mA (ll I1-I2 ll ≥4 mA).

‘Linear’
The symbol
‘Linear’
appears on the LCD screen. You can enter any
stroke rate- behaviour of the pump proportional to the current signal. For
this purpose, enter any two points P1 (I1, F1) and P2 (I2, F2) (F1 is the
stroke rate at which the pump is to operate at current I1, F2 is the stroke
rate at which the pump is to operate at current I2...); this defines a straight
line and thus the behaviour is specified:
