Isopotential Point
This option allows the user to edit the isopotential point of the electrode used for ion measurements. The ion
selective electrodes have different isopotential points. If temperature compensation is desired for the ion
measurements, the isopotential point value is absolutely necessary.
The isopotential point is always edited in ppm (mg/L) units.
To set the Isopotential Point:
• Press
while in
ISE Measure
mode.
• Press
.
• Use
or to select the Isopotential Point option.
• Press
and use or to increase / decrease
the isopotential point value.
• Press
key to save the modified value.
• Press
to return to the Ion Setup options. If the Saving
Confirmation is enabled, press
to accept the modified option,
to escape without saving or to return to the editing
mode. Otherwise, the modified option is saved automatically.
Note: If an ISE calibration was performed and the Isopotential Point option is changed, a warning message
appears on the LCD informing the user to perform a new calibration or to set the previous option in order
to perform accurate measurements.
ISE Significant Digits
Accessing this option, the number of ISE significant digits can be set, with one (x), two (xx) or three (xxx)
significant digits.
To set the ISE Significant Digits:
• Press

ISE Measure
mode.
• Press
.
• Use
or to select the ISE Significant Digits
option.
• Press
