“Auto pH Acid Slope Calibration”
The current pH reading and temperature are shown for
the selected channel in this screen along with the
existing currently used acid slope calibration as well as
the time since this calibration was last performed.
Choices of pH buffer for auto acid slope cal are 4.00 or
1.68. After selecting buffer click on “Calibrate” button.
If calibration is successful then “Calibration Complete”
is shown. After dampener time expires the new
calibration result will be shown and the time since
calibration will show as 0.00 days. The exact value of
pH buffer at cal temp shown as “Calibrated Value”.
“Auto pH Base Slope Calibration” Menu
The current pH reading and temperature are shown for
the selected channel in this screen along with the
existing currently used alkaline slope calibration as well
as the time since this calibration was last performed.
Choices of pH buffer for auto base slope cal are 10.00 or
9.18 or 12.45. After selecting buffer click on “Calibrate”
button. If calibration is successful then “Calibration
Complete” is shown. After dampener time expires the
new calibration result will be shown and the time since
calibration will show as 0.00 days. The exact value of
pH buffer at cal temp shown as “Calibrated Value”.
“Manual Calibrate” Menu
The available choices for manual calibration of a pH
sensor are shown to the right.
The slope calibration is only available when the sensor
type is pH. In addition the pH offset calibration must
always be performed before the slope calibrations can be
performed.
