Press
to delete the selected calibrated point and then press to update
calibration with the new standard solution.
If the isopotential point of the electrode is unknown,
the ISE calibration and measurements can be
performed without temperature compensation (see
ISE Setup, Temperature option for details).
When in MTC mode, after selecting a standard press
, a pop-up menu will be displayed on the
LCD in which the concentration and the temperature
value can be adjusted by pressing
and then
or keys. Press to save
the modified value and then
/
to select next/previous value to be adjusted. MTC
value will have no effect on measurement but will
be included on log data.
CALIBRATION MESSAGES
• Wrong standard solution. Check the standard solution: this message appears when the
difference between the reading and the value of the selected standard solution concentration is
significant. If this message is displayed, check if you have selected the appropriate calibration
standard.
• Standard to close. Check the standard or clear calibration: this message appears when
the difference between current ISE standard and the already calibrated standard is too low.
• Slope to low/high. Check the standard solution. Recalibrate using fresh standards.
• Difference between standards temperature is too high. Press
to update calibration
or clear old calibration.
