Measuring ion concentration in the Direct Reading with
Standards Mode
With Auto Read on
1. Add Ionic strength adjuster to the sample.
2. Immerse the ion selective electrode in the stirring sample.
3. Touch meas to begin measuring your sample. The meter will
accept the reading and display STABLE when the measurement
meets the selected stability criteria. The measure screen will fix
onto this measurement and will not deviate until meas is touched.
4. Repeat steps 1-3 with additional sample.
With Auto Read off
1. Add ionic strength adjuster to the sample
2. Immerse the ion selective electrode into the stirring sample. The
meter will continually monitor the ion concentration value. When
the meter recognizes the reading as stable, STABLE is displayed
on the measure screen. With the Auto Read function deactivated,
the display on the measure screen will indicate any deviation in
the concentration.
3. Repeat steps 1-2 with additional sample.
