Operating the valves and valve drives
Set the position manually on the valve.
Press one of the two buttons to adjust the value of the cur-
rent injection position. The [<] button reduces the value of
the injection position; the [>] button increases it.
Practical tip!
If several valves are switched in series, then the injection posi-
tions are synchronized simultaneously on all valves.
Filling the sample into the sample
loop
Prerequisites
The sample loop was mounted between the positions 2
and 5
A syringe connection was mounted on the desired connec-
tion.
There are no air bubbles in the injection syringe.
Caution!
Damages to the valve due to pointed injection
syringes! Use only injection syringes with luer lock
and flat-ground cannula.
Set the valve to L (= load) to be able to fill the sample loop.
