916 Ti-Touch

The algebraic sign of the stirring rate changes the direction in which the
stirring is done. When the stirrer is viewed from above, this means:

"+": counterclockwise rotation

"–": clockwise rotation

Input range

–15 - 15

Default value

8

Switch off automatically

on | off (Default value: on)

If this parameter is activated, the stirrer will be switched off automatically
at the end of the titration, measurement, etc.

28.6.1

Calibration parameters (CAL pH)

Under [Calibration parameters], the parameters influencing the
sequence of the entire calibration are defined.

Signal drift

Maximum permissible drift for the measured value acceptance, i.e. maxi-
mum change of the measured value per minute. For this value, a suitable
maximum waiting time is automatically calculated except you already have
modified this waiting time.

Input range

0.1 - 999.0 mV/min

Default value

2.0 mV/min

Selection

off

off
Measured value acceptance will take place after the maximum waiting
time has elapsed.

Min. waiting time

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

10 s

Max. waiting time

If the 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. As default value, a suitable waiting time for the signal drift is
automatically calculated.
