877 Titrino plus

Sensor
Selection of the sensor from the sensor list. The selection depends on the
measuring mode. Sensors are defined under System
▶ Sensors.
Selection Selection of configured sensors
Stirrer
When this parameter is switched on, then the stirrer is switched on at the
start of the determination.
Selection on | off
Default value on
Stirring rate
Setting the stirring rate. It can be set in steps of –15 to +15. The default
setting 8 corresponds to 1000 U/min. The formula for calculating the rota-
tional speed is specified in chapter 10.2, page 102. The optimum stirring
rate can be tested in the manual control.
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
Sample changer
This parameter must be switched on for automatic calibrations with sam-
ple changers (e.g. 869 Compact Sample Changer). Because the buffers are
changed by the sample changer, the run is not paused in order to request
values). The 877 Titrino plus sends a signal (EOD) to the sample changer
via the remote connection as soon as the measurement of one buffer has
been completed (see Figure 23, page 109). The sample changer switches
to the next buffer at that time.
The parameterization of the sample changer is described in the corre-
sponding manual.
NOTE
We recommend that the stirrer be connected to the sample changer
when calibrating with a sample changer. The Stirrer parameter must
however be switched off in such cases.
