Measured value acceptance will take place after the maximum waiting
time has elapsed. This can be useful when the titration reaction pro-
ceeds slowly or the electrode is slow to respond.

Measuring mode Upol:
Input range

0.01 - 99.90 µA/min

Default value

50.00 µA/min

Min. waiting time

This parameter is visible only when Titration rate = user.

The measured value is not accepted until the minimum waiting time has
elapsed, even if the signal drift has already been reached. The minimum
waiting time is only important for drift-controlled measurements.

Input range

0 - 999999 s

Default value

0 s

Max. waiting time

This parameter is visible only when Titration rate = user.

If signal drift has been switched off or has not yet been reached, then the
measured value will be accepted when the maximum waiting time has
elapsed.

Input range

0 - 999999 s

Default value

26 s
