• Press
to change the desired method parameters as indicated in the first step of the method.
• Press
to take the second mV reading.
• When the reading is stable, press
to store the second mV reading. The ISE measurement results
will be displayed on the LCD.
• Press to log the current results into a ISE Method Report or press to return to
ISE
Measure
mode.
• If pressing
, the method parameters can be changed and the sample concentration will be
recalculated.
• Press
to start another measurement.
Note: Press
at any time to stop the measurement and return to
ISE Measure
mode.
ANALYTE ADDITION
To measure the concentration of a sample using the Analyte Addition incremental method:
• Press
and then to select
ISE Measure
mode for the selected channel.
• Select the Analyte Addition method (see ISE Setup for details, page 33).
• Press
to start the measurement. The first step of the method will be displayed on the LCD in
which the user is notified to add the appropriate ISA Buffer Volume (if different from 0 mL) to the standard
and to immerse the electrode into the Standard Volume of set concentration. The method parameters are
also displayed on the LCD.
• Press
to set the method parameters. Press / to select next/previous parameter
to be edit, then press
and use or to set the desired parameter value. Press
to save the modified value and then press to exit method parameters edit menu.
• Make sure that the set parameters values are the used ones and submerge the Ion Selective Electrode tip
approximately 4 cm (1½”) into the standard solution.
• Press
to take the first mV reading.
• When the reading is stable, press
to store the first mV reading. The second step of the method
will be displayed on the LCD in which the user is notified to add the Sample Volume to the standard
solution. The method parameters are also displayed on the LCD.
• Press
to change the desired method parameters as indicated in the first step of the method.
• Press
