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
DOWNSCROLL
key to initiate calibration.
Note.
To abort calibration, press the
DOWNSCROLL
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 5.1.3) 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 (dual input analyzers only) calibration is identical to
Sensor A calibration.
Probe Type for Sensor B (dual input analyzers only) set to Redox or
ORP and Enable Cals. set to No (Section 5.1.3) – return to top of
page.
Alter Sec. Code not set to zero (Section 5.1.8) – see Section 5.1.1
Alter Sec. Code set to zero (Section 5.1.8) – see Section 5.1.2.
