Operation
➜
Swipe a finger from left to right or from right to left over the field to start and re-stop the
rotational movement.
After a process, stop the rotational movement actively with the swipe
field as described above.
Otherwise the device behaves as described in section „Automatic restart"
on page 58 and possibly restarts automatically!
Enhanced Hei-TORQUE Ultimate functions

Calibrating the torque
To adjust to the individual environmental conditions on site and for precise display in the
process, the Hei-TORQUE Ultimate type devices provide the option of calibrating the device's
torque. The following options are available:
➜
Relative zero point: the zero point of the torque with immersed stirrer tool is determined
here, i.e., the value results from the resistance of the sample.
➜
Absolute zero point: the zero point on the load-free rotating stirrer tool is determined here.
Before the calibration the device must warm up for 15 – 30 minutes to
compensate for the temperature-dependent resistance of the gear unit.
