2.
Press the CAL button or up/down button with the Measurement Top screen
appearing until the process display shows [Auto Zero Calibration].
The automatic zero calibration mode is entered.

3.
Use the measuring cylinder or measuring syringe (for solvent) to dispense 8 mL of
zero liquid for calibration through the sample inlet.
4.
Use the dropper to add one drop of hydrochloric acid through the sample inlet.
5.
Use the measuring cylinder or measuring syringe (for sample) to dispense 16 mL of
clean water through the sample inlet.
6.
Press the ENT button.
If the set [Number of Purge] has not been completed:
The purge sequence starts. The screen title changes to [Auto Zero Calibration
(Purge: 1)], and the process display changes as follows as the sequence
progresses:
[Extraction]
→
[Layer Separation]
→
[Fill Cell]
→
[Drainage]
The remaining time of the current process is shown (counting down).
When the purge sequence ends, the start state of the automatic zero calibration
mode returns.
When the remaining [Number of Purge] is 0:
The measurement sequence starts. The screen title changes to [Auto Zero
Calibration: Measurement], and the process display changes as follows as the
sequence progresses:
[Extraction]
→
[Layer Separation]
→
[Fill Cell]
→
[Calibration]
The remaining time of the current process is shown (counting down) during
extraction, layer separation, and cell filling. The elapsed time is shown (counting up)
during calibration. When calibration ends, the calibration result appears.
After the result appears, the measurement liquid is drained. During drainage, the
process display on the screen shows [Drainage].
