7.3 Calibrating the peristaltic pump
Every 6 months and/or after a hose change, the pumping rate of the peristaltic pump must be checked and, when necessary,
adjusted. For this purpose, place the sample scales with a beaker into the magnetic stirrer and switch on. If necessary, press the
“TARE” button in order to reset the value to 0.00g.
Then select the calibration menu for the peristaltic pump. The test period of two minutes is represented by a progress bar on the
display. On completion of this process, the pumping rate of the pump is shown on the display of the scales and can be edited using
the “+” and “-“ buttons in the following menu and subsequently confirmed by clicking <OK>.
8 Manual stirring mode
The “Magnetic stirrer” menu option enables manual starting of the stirrer in order to measure the pH, for example. The speed can be
increased and reduced using the +/- buttons of the controller. Press the <ESC> button in order to switch the stirrer off again. The
operating time is limited to 20 minutes. The display shows the remaining operating time.
