3.
Set the measurement condition in the Sample add. method (Single) screen.
Enter sample volume, concentration of the additive standard solution, volume of the
additive standard solution and electrode slope.
4.
Tap
key after complete setting.
The MEAS screen is displayed.
To return the set value to default, tap the
Setting item and range
Volume of the additive sample solution:
Electrode slope:
Concentration of the standard solution:
Standard solution volume:
HINT!
For more accurate measurement:
Normally, the amount of the standard solution to be added should be from 0.1% to 10% of
the sample solution. It is desirable that when the standard solution is added to the sample
solution, the concentration of the ion species under measurement increase by 1 time to 10
times in the sample solution. If the concentration of the added standard solution is too low
or if the volume of the added standard volume is larger than that of the sample, a large
error may occur in the measurement result.
5.
Immerse the ion electrode in standard solution and tap
The measurement starts. When the indication stabilizes, the HOLD indicator lights up
and the measurement value is determined.
6.
Tap
to proceed to the next measurement.
7.
Immerse the ion electrode in the 1 sample solution and tap
The measurement starts.
When the measurement is completed, concentration of the sample and the measuring
condition are displayed as measurement results.
