7.2 Sample measurement
7.2.1 When the built-in syringe is used
7.2.1.1 Sampling test materials
1.
Make sure the sample discharging lever is pushed down
to the bottom.
2.
If not, slowly push it down with your thumb.
3.
Dip the sampling nozzle in the sample liquid.
4.
Slowly pull the sampling lever with the forefinger.
When the cell is filled with sample, release your finger.
Caution!
Be sure to rinse the built-in syringe by repeating sampling of pure
water after a day’s measurements. Failure can lead to the
solidification of a sample (e.g. Sulfuric acid). If the syringe should be
forced to be moved in this solidification state, it would scratch the
inner surface, causing a possible leakage of a sample inside DA-130N.
7.2.1.2 Start measurement
Only when
is displayed (Stability:Auto), start measurement with [ok/meas.] key.
7.2.1.3 Hold measurement data
When
is displayed (Stability:Auto), the value will automatically turn to reversed when the reading
stabilizes.
If
is not displayed (Stability:Manu), wait until the reading stabilizes, and press [ok/meas.] key. The
reading will be withheld shown in reversed mode.
7.2.1.4 Saving measurement data
When is displayed (memory in: Auto), the reading will be automatically saved if retained.
If is not displayed (memory in: Manu), press [ok/meas.] key while the reading is withheld. The data
at this point will be saved.
