Calibrate Metered Volume - Heidolph PD 5001 Mode D'emploi

IEI
Volume is displayed (41) in ml.
-
Desired volume can be selected with arrow keys (35).
-
At this point the processor is going to determine the number of revolutions required.
-
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.

9.3.6. Calibrate metered volume

Determine and set speed by your actual requirements
-
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.
Enter hose data and volume to be metered, as described under 10.3.5.
-
Hit „Start Stop" key (32).
-
Pump is going to feed fluid at the speed and volume entered before.
-
Determine exact quantity of fluid collected.
-
Hit „Cal" key (34). Display (41) flashes.
-
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.
Enter value so determined with arrow keys (35).
-
Hit "Cal" key (34) and hold depressed for not less than 3 seconds to enter. Data in memory
-
are revised. "Cal" is displayed (41) for about 2 seconds to confirm action.
Enter volume wanted with arrow keys (35).
-
Programmed flow rate and hence volume metered, are a function of pump head and
hose selected. If, during calibration, the user finds a deviation in excess of 30 %, a
setting error is very probable. In this case discontinue calibration (hit "select" key once),
and go ahead checking the following parameters:
did you select the right pump head (Chapter 10.3.1)?
-
did you choose the right hose (Chapter 10.3.3)?
-
is the hose properly installed in the pump head (Chapter 3) ? Is the clamping action
-
ok ? (Chapter 3)
If wrong parameters have been entered for calibration of metered volume, metering
action cannot be started with the "Start" key. The select LED will turn to „Flow ml/min",
and 4 dashes (----) are displayed.
Correct wrong parameters as described below:
go into feed rate graph (Chapters 17 & 18) and determine a speed figure (1/min)
-
plus a logical feed rate (ml/min).
go to "speed" menu (1/min) with select key and choose a speed with arrow keys.
-
go to "flow" menu (ml/min) with select key and choose a feed rate from the graph,
-
as described under Chapter 10.3.4.
at this point, a reasonable feed rate is saved.
