The S2Ca can also run in calibration mode. The corresponding continuous displays show the
current dosing quantities or the feed rate.
The calibration is retained in the event of a change of the set stroke length by up to ±10 scale
rates percent (if the stroke length is set to 40 % the range is 30 % to 50 %). If the stroke length
is changed by more than ±10 scale rates percent the yellow warning light lights up, the perma-
nent display flashes and the flashing “Calib” indicator appears.
NOTE
• Do not go below 30 % stroke length (SEK type: 50 %).
This will significantly affect accuracy of calibration.
• Calibration becomes increasingly accurate the more strokes made by the S2Ca during
calibration (recommended: at least 200 strokes).
WARNING
If using a hazardous feed chemical, the following setting instructions ensure adequate
safety precautions are taken!
Calibration ̈ Insert the suction tube into a measuring cylinder containing the feed chemical - the
discharge tubing must also be correctly installed (operating pressure,…!)
̈ Suck up the feed chemical (press both arrow keys at the same time) when the suction tube
is empty
̈ Note the liquid level in the measuring cylinder and the stroke length
̈ Select the CALIB menu and go the first menu option using the P key
̈ Select “ON” using an arrow key and change to the next menu option using the P key
̈ To commence calibration, press the P key. The S2Ca starts to pump and displays the
number of strokes (“STOP” appears at regular intervals)
̈ After a sufficient number of strokes, stop the S2Ca with the P key
̈ Calculate the dosed quantity (difference between the original quantity and the quantity
remaining)
̈ Enter this quantity in the next menu option and then change to the following menu option
by pressing the P key.
̈ Select the unit (“L” or “gal”) in the “UNIT” menu with an arrow key and push the P-button.
The S2Ca is calibrated.
The corresponding continuous displays show the calibrated values.
The total stroke number and total litres are set during calibration to “0”.
The S2Ca is in the STOP status.
