ProMinent DULCOMETER pH/mV/Pt 1000 Mode D'emploi page 36

Operation
• Calibration of buffer 2 starts 2 sec after pressing the keys CAL, "UP" or
"DOWN", as above; marker "P2" is displayed steadily.
• After successful calibration the LCD elements "P1" and "P2" are switched
off and the new calibrating data is displayed:
•
•
• The meter display returns to the measuring operation previous to the
calibration. If the temperature was being measured, the parameter pH is
selected.

• Press the key "CAL" followed by the key "pH/mV/°C" to display the
calibrating data again later.
• The meter display returns to the measuring operation previous to the
calibration. If the temperature was being measured, the parameter pH is
selected.
6.4.3
• Press the key "pH/mV/°C" after successfully calibrating buffer 1 to
discontinue the calibration process.
• The calibration is now interpreted as a 1-point calibration and new
calibrating data are displayed. Depending on the value of the selected
buffer, the zero point or slope are calibrated:
Selected buffer value:
New calculation of:

zero point for 2 sec with activated LCD elements "cal" and "∆pH", and
afterwards
slope for 2 sec with activated LCD elements "cal" and "%".
