Menu (details):
Stirring:
Speed Limit:
The “
Manual
“ option allows you to set the desired maximum
speed limit for the stirrer. The initial setting is the maximum per-
missible speed of the stirrer. If you change this setting, the
WiCo
saves the new value for future stirring tasks.
If the “
Speed Limit
” has been changed, then the speed can be
adjusted only within the new range.
Under the stirrer elements type, the maximum speed limit
is set automatically by the selected stirrer element, e.g. the
maximum speed is limited to 1000 rpm when anchor stirrer
R
1330 is selected.
For detailed information, refer to section “Permitted
IKA
®
stirrer
tools”.
Torque Limit:
The ”
Torque Limit
” menu allows you to set the desired maximum
deliverable torque limit. The initial setting is the maximum permis-
sible torque of the device.
If you change this setting, the
WiCo
saves the new value for fu-
ture stirring tasks.
If the “
Torque Limit
“ has been changed, the stirrer can deliver an
operating torque only up to the value specified as the maximum
torque limit.
Note:
The torque limit can be overload for about 10 seconds. This
is necessary to cater for stirring tasks which require metering and
feeding additives.
Torque Display:
The ”
Torque Display
” menu allows you to specify that the
torque is shown in the display. A tick shows that the option is
activated.
Note:
Pressing the "
Back
" button while the device is running
resets the torque to 0 Ncm. The Δ symbol then appears in the
display in front of the torque value.

Torque Calibration:
This menu allows the torque to be calibrated. All torque resulting from bearing friction is excluded from the torque calculation. This is
performed with no stirrer element attached. A duration of 30 seconds and speed of 50 rpm are set automatically.
Note:
Calibration can be performed only when a USB cable is being used. For this, remove the
WiCo
from the station (see "
Interfaces
and outputs
" section, figure “
Connection capability: WiCo to the station
“).
