Commands 479
Stirring rate
-15 ... [ 8 ] ... 15 (Titrando only)
Setting the stirrer speed. The direction in which stirring takes place changes
as the sign in front of the stirrer speed changes.
Switch off automatically
[ on ], off (Titrando only)
The stirrer is automatically switched off at the end of the command if this
option is activated.
Measuring parameters
The measuring parameters are defined on this tab.
Command name
25 characters, [ MEAS T # ]
Name of the command.
Measurement
The two measuring modes Measurement with drift control or Meas-
urement without drift control are selectable.
Note
A constant measured value is often only achieved after a certain time, as mixing
and possibly the reaction itself require a certain time. The response time of an
electrode can also increase with time, i.e. reaching a constant measured value
takes longer and longer. In such a case
drift-controlled measurement is par-
ticularly advisable, as the measured values are only accepted when equilibrium
has almost been achieved.
Measurement with drift control
[ on ], off
The measurement is carried out drift-controlled if this option is activated.
The measurement is stopped as soon as the Signal drift or the Stop meas-
ured value is reached or a waiting time has elapsed. The corresponding pa-
rameters are not visible if this option is deactivated.
Signal drift
0.1 ... [ 0.5 ] ... 999.9 °C/min (Titrando)
[ 0.5 ] ... 999 °C/min (Titrino)
The measured value is only accepted if the signal drift defined here has
been fallen short of.
