[Drift Stop]
Selection of three modes by drift level as follows:
x Off ： Regardless of drift level, end point is determined when [t(stir)]+ [t(wait)]+
[t(max)] elapses. This mode is useful when end point is not found by drift or
when the amount of water extraction per unit time is needed.
x Rel. ：This mode determines end point when the drift level during titration goes
down below [Drift at time of start] + [Relative drift]. This mode is typical for
regular direct titration method.
x Abs. ：Regardless of drift level at start, end point is determined when the drift
level during titration goes down below [Absolute drift] level. In this mode,
titration will not end if the drift level at the end of titration goes up. To prevent
this, select a [t(max)]to end the titration.
[Rel. ]
Here you enter a relative drift level. This entry appears only when “Drift stop” is
set to “Rel.”.

[Abs.]
Enter an absolute drift level. This entry appears only when “Drift stop” is set to
“Abs.”
