…4.1 Sensor Calibration
…4.1.5 Manual, Single- and Two-Point Calibration (pH Only)
…4 SETUP
Calibrate Buffer 2 (Two-Point Calibration only)
Immerse Sensor A in the second buffer solution.
pH
and
Adjust
are shown alternately on the upper display line. Use the and keys
to set the displayed pH value to the temperature-corrected pH value of the chosen solution
(see the datasheet provided with the solution).
Press the key to initiate calibration.
Note. To abort calibration, press the key again at any time before calibration is
complete – see previous page.
Measured pH value from the last successful calibration.
Measured sensor output in milivolts.
When the measured sensor output stabilizes, press the key to accept the calibration.
Cal. Accepted
is shown for 2 seconds to confirm that the calibration has been accepted,
the display then advances automatically to the next frame.
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
Set Min Slope
– Section
5.3) and 105% is displayed. If the value is outside these 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.
Sensor B calibration (dual input analyzers only) is identical to Sensor A
calibration.
