Temperature Compensation
ISE measurements benefit from temperature compensated corrections if:
• standards and sample temperatures differ from each other
• the Isopotential Point of the ISE is known.
If sample and standards are made at the same temperature, leave this option disabled.
Isopotential Point
If the Temperature Compensation is enabled, the isopoten-
tial point of the ISE must be added in this parameter. Verify
the Electrode Type and Concentration Unit are configured
for the desired application. The Isopotential point will use
the selected concentration unit. Use
and
to edit the isopotential point value and press to
save the value or press to cancel operation.
Notes: A warning message will appear on the LCD
informing the user to perform a new calibration.
A minimum of two ion standards is required for the
ISE calibration.
Calibration
This option allows the user to view and configure all ISE parameters related to ISE calibration.
Manual Entry
Two different standard groups can be used for calibra-
tion of ISE:
All Standards - During calibration the user can select
the desired standards from a large list containing all the
predefined standard values and the custom standards.
Group Standards - the user can pre-select a group of
standards from the existent group of standards to be used
during sensor calibration.
