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 calibration 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.
To set the Manual Entry:
• Press
while in
ISE Measure
mode.
• Press
.
• Use
or
to select the Calibration option.
• Press
and use
or
to highlight the Manual Entry option.
• Press
or
to select the desired option.
Edit Custom Standards
Use
Edit Custom Standards
function to add additional ISE standard
values. Up to five custom standard values can be added. Set
Electrode Type
and
Concentration Unit
prior to adding these
standards.
To edit/set the Custom Standards:
• Press
while in
ISE Measure
mode.
• Press
.
• Use
or
to select the Calibration option.
• Press

----
”) or press
to
cancel the operation.
• Use
key to select the next custom standard to be set.
• Press
to return to Edit Custom Standard options.

• To select the appropriate
Ion Charge/Slope use
or
and then press
. If the Ion electric charge is
None, its slope can be manually set by pressing
.
A pop-up menu will be displayed on the LCD, in which the slope
value can be set using
or
. Press
to
save the modified value or press
to return to the previous
menu.
Note:
If an ISE calibration was performed and a different Ion
Selective Electrode is selected (standard or custom), a
warning message appears on the LCD informing the user to
perform a new calibration or to select the previous ISE in
order to perform accurate measurements.
Concentration Unit
Select the desired concentration unit for the measured Ion or chemical compound. The available concentration
units are: ppt, g/L, ppm, mg/L, µg/mL, ppb, µg/L, mg/mL, M, mol/L, mmol/L, %w/v and User (custom
unit).
To set the Concentration Unit:
• Press
while in
ISE Measure
mode.
• Press
.
• Use
or
to select the Concentration Unit option.
• Press
and use
or
to highlight the
desired option.
• Press
to confirm your selection or press
to
cancel operation.

Log
- See pH Setup section.
Note
: The Logging Data Configuration option includes also the Ion Constants parameter. If you want it to appear
in the log reports, it must be enabled.
Alarm
- See pH Setup section.
Note
: The Alarm Limits (Low and High) are set in the selected concentration unit of the measured Ion.
