Since every hose has its own tolerance, it will be required to calibrate the pump drive for a
-
particular hose, if high accuracy is mandatory.
For geared pumps, the „tube mm" menu is skipped, and „----" displayed instead.
-
Caution: with reference to the very small quantities involved, feed rate is displayed in
μl / min, when " Cassette small and hose size 0.2 0.5 or 0.9 are selected.
9.3.4. Calibrate feed rate
Enter hose data and feed rate wanted, as described under 10.2.3.
-
Hit „Cal" key (34). Display (41) flashes.
-
Hit „Start Stop" key (32).
-
The pump is going to run for 1 minute exactly. Collect fluid and determine quantity.
-
Enter value so determined with arrow keys (35).
-
Hold "Cal" key (34) depressed for not less than 3 seconds to save value. Data in memory
-
are revised. "Cal" is displayed (41) for about 2 seconds to confirm action.
Select actual feed rate wanted with arrow keys (35).
-
Caution: with reference to the very small quantities involved, feed rate is displayed in
μl / min, when " Cassette small and hose size 0.2 0.5 or 0.9 are selected.
9.3.5. Metering by volume
There is a minimum allowable metering volume that depends upon the set speed and
the hose diameter. Lower values can only be achieved with smaller hoses. (see page
178)
The PD5206 drive can only meter with a maximum of 300 l/min for reasons of
precision! During the metering process, the drive is automatically limited to 300 l/min.
The LED Speed rpm and the display blink before the metering process as an
indication.
The pump drive features metering of a certain volume of fluid. Once set, this quantity may be
-
fed no matter how often by just hitting the Start/Stop key (32) or by triggering the interface
(37/39). Max volume is 9999 ml
To select a certain volume, you first need to enter hose ID.
-
Feed rate is proportional to the number of rotations and hose ID.
-
Enter hose ID: hit select-key (36) until „tube mm" LED lights.
-
Enter actual hose ID with arrow keys (35) (e.g. 0.8; 1.7; 3.1; 4.8; 6.3 or 7.9).
-
If the LED Vol ml blinks when you adjust the internal diameter of the hose, the
metering volume is being adapted to the minimum allowable volume!
Hold select-key (36) depressed until „Vol ml" LED lights.
-
Caution: with reference to the very small quantities involved, feed rate is displayed in
μl / min, when " Cassette small and hose size 0.2 0.5 or 0.9 are selected.
