Calibrate Buffer 2 (Two-Point Calibration only)
Immerse Sensor A in the second buffer solution.
Press the key to initiate calibration.
Note. To abort calibration, press the
complete – see previous page.
The center display line shows the measured sensor output in millivolts.
As calibration procedes, a progress indicator appears in the lower display line. When the
measured sensor output stabilizes, the lower display line shows
The display then changes for 2 seconds to show the temperature-corrected buffer value in
the upper display line, then advances automatically to the next frame.
Calibration Message
See Table 4.1 for details of calibration messages.
Slope Value
% slope value.
A value between the programmed minimum % slope value (see
page – Section 5.3) and 105% is displayed. If the value is outside these
CONFIG. SENSORS
limits, check the electrode system.
pH check value.
Displayed as an additional indication of electrode system condition; 7pH is the optimum
value for glass electrodes and 0pH for Antimony electrodes.
