7. Press the key or the key.
The value is set to the displayed value, and the mode is changed to Low
concentration calibration.
Tip
You can finish calibration by pressing the key.
8. To perform the 2nd point calibration, clean the DO electrode well in the same
manner as the step 1. and immerse it in the second standard solution (low-
concentration solution).
Note
When using an electrode "9551-20D" or "9551-100D", immerse at least 9 cm from the tip.
9. Immerse the DO electrode in the standard solution.
As with the step 4., immerse at least 6 cm of the tip of the DO electrode. Stability
judgment starts and the DO icon blinks. When the value is stabilized, the DO icon
changes from the blinking state to the lit state.
10. Press the key to enter DO (DO concentration) value of the solution to be
used for calibration.
