• Press to confirm your selection or press to cancel operation.
Note: If an ISE calibration was performed and the Temperature Compensation 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.
Calibration
This option allows the user to set all the data regarding the Ion calibration process.
Standard Entry Type
Two entry modes for the standard solutions used for calibration are available:
Manual Selection
– when the calibration is started, the desired standard solution can be manually selected from
a standard solutions list (0.1 ppm, 1 ppm, 10 ppm, 100 ppm and 1000 ppm).
Custom Standard
– when the calibration is started, each standard solution can be manually set (in ppm units) in
a displayed pop-up menu.
To set the Standard Entry Type:
• Press
while in ISE Measure mode.
• Press .
• Use or to select the Calibration option.
• Press and use or to highlight the
Standard Entry Type option.
• Press and use or to highlight the
desired option.
• Press to confirm your selection or press to
cancel operation.
Calibration Reminder – See Calibration option from pH Setup section, page 20.
Set Reminder Period – See Calibration option from pH Setup section, page 20.
Clear Calibration – See Calibration option from pH Setup section, page 20.
Electrode Type
This option allows the user to select the desired Ion Selective Electrode used for measurements from a list:
Ammonia, Bromide, Cadmium, Calcium, Carbon Dioxide, Chloride, Chlorine, Cupric, Cyanide, Fluoride, Iodide,
Lead, Nitrate, Potassium, Silver, Sodium, Sulfate, Sulfide and five custom ISE. For the standard ISE it is possible
to view the Ion constants (Name, Molar Weight and Electric Charge/Slope), while for the custom ISE all these
constants can be manually set.
