To Set Isopotential point
The Isopotential point is the millivolts reading for an electrode at
which temperature has no effect on the measurement. Ion selective
electrodes, unlike pH electrodes, are not designed to achieve any
particular isopotential point. If samples and standards are at different
temperatures when performing ISE experiments, it will be necessary
to experimentally determine the isopotential point of your own Ion
Specific Electrode.
The Ion Isopotential Point is set the same way as previously
described in pH setup. See page 58 for instructions.
To Set Alarm Limits
This option allows you to set alarm limits for the Ion measuring mode.
If the ion concentration measurement is outside the boundaries set by
the minimum and maximum limits, an audible alarm and/ or a visual
warning will appear to let you know that your sample measurement
was outside of the set limits.
The Ion Alarm Limits is set the same way as previously described in
pH setup. See page 60 for instructions.
To Set Print Criteria
This screen allows you to select which criteria are printed with the
measurement when you print the data or send it to the computer. The
status of the current print criteria is displayed on the screen. The
criteria option is active if “ON” appears to the right of the option. It is
inactive if “OFF” appears to the right of the option. Any active criteria
will be printed on demand.
The Ion Print Criteria are set the same way as previously described in
pH setup. See page 62 for instructions.
To Set Print Interval
You have three options for setting the print interval: manual printing,
stable reading printing and timed interval printing.
The Ion Print Interval is set the same way as previously described in
pH setup. See page 64 for instructions.
To Set Data Storage Criteria
This screen allows you to select what criteria are stored in the meter’s
memory with the measurement when you save the data. The status
of the current data storage criteria is displayed on the screen. The
criteria option is active if “ON” appears to the right on the screen. It is
inactive if “OFF” appears to the right of the option. Any active criteria
will be stored with the measurement. All storage criteria will be stored
in the meter’s memory with the measurement. However, only active
items will appear on the View Stored Data screens. Changing the
status of the storage criteria to active from inactive will allow the
criteria to be displayed with the previously stored data.
The Ion Data Storage Criteria is set the same way as previously
described in pH setup. See page 66 for instructions.
