Parameters for preparation
Configures the parameters to be used in the commands PREP and EMPTY .
Dosing port Prep/Empty
[ Dosing port 1 ], Dosing port 2, Fill port, Special port
Dosing port via which the cylinder contents are to be ejected during prepa-
ration and emptying.
Dosing rate Dosing port 1
0.01...166.00 mL/min, [ maximum ]
Speed at which dosing is to be carried out at Dosing port 1. The maximum
dosing rate depends on the cylinder volume of the dosing unit used (see
below). When the function is carried out the speed will automatically be re-
duced to the largest possible value.
Dosing rate Dosing port 2
0.01...166.00 mL/min, [ maximum ]
Speed at which dosing is to be carried out at Dosing port 2. The maximum
dosing rate depends on the cylinder volume of the dosing unit used (see
below). When the function is carried out the speed will automatically be re-
duced to the largest possible value.
Dosing rate Fill port
0.01...166.00 mL/min, [ maximum ]
Speed at which filling is to be carried out at the Fill port. The maximum fill-
ing rate depends on the cylinder volume of the dosing unit used (see be-
low). When the function is carried out the speed will automatically be re-
duced to the largest possible value.
Dosing rate Special port
0.01...166.00 mL/min, [ maximum ]
Speed at which dosing is to be carried out at the Special port. The maxi-
mum dosing rate depends on the cylinder volume of the dosing unit used
(see below). When the function is carried out the speed will automatically
be reduced to the largest possible value.
Maximum Dosing/Filling rate for dosing unit as a function of the cylinder volume:
Cylinder volume Maximum rate
2 mL 6.6 mL/min
5 mL 16.6 mL/min
10 mL 33.3 mL/min
20 mL 66.6 mL/min
50 mL 166.0 mL/min
Enter lower rates for high-viscosity liquids.
Tubing parameters
Defines the length and diameter of the tubing connected to the dosing unit. The
port occupancy can also be altered. These parameters are important for carrying
out the dosing unit commands
PREP and EMPTY correctly, as the volumes of the
tubing connections have to be taken into account.
Note
Default values have already been entered for the tubing parameters; these cor-
respond to the dimensions of the standard tubing supplied. If you do not make
any alterations to the tubing connections then you do not need to alter the tubing
parameters.
