Safe / Visc:
Once the “VISC / SAFE“ has been set to “VISC“, the viscosity trend value will be shown on the
display� The torque trend measurement is used to deduce the change in viscosity of the reaction
medium� The devices are not designed to measure absolute viscosity� They only measure and
display the relative change in the viscosity of the medium from a starting point specified by the
user�
Once the speed of the motor and magnetic rod in the medium have stabilized to the target
speed, the viscosity measurement is started at 100 %� The change in the viscosity is then shown
in %�
The value can always be reset to 100 % by pushing the „Menu“ button for 2 seconds�
! Notice!
Torque trend measurement only works for a constant set speed for the duration of the meas-
urement� As a result, intermittent mode cannot be used in conjunction with torque trend meas-
urement�
The current control variable is saved as the reference 100 % ΔP and shown on the digital dis-
play� The change in the viscosity is then shown in %�
When on the “VISC“ screen, the screen will switch to “SAFE“ if the adjustment of the safety
temperature is activated, during which you may set the safety temperature and the screen will
switch back to “VISC“ once the setting is done, otherwise it will switch back to “VISC“�
Factory reset:
The menu item ”Factory reset” allows the user to reset all the system settings to the original
standard values set at dispatch from the factory (see “Menu structure”)�
Probe calibration:
In order to use tolerances to limit temperature deviations, the user can calibrate the tempera-
ture sensor in conjunction with the device�
2-point calibration:
Calibration using two temperatures�
! Notice!
For calibration, select a suitable stirring speed for the application�
Use a calibrated temperature reference meter for control�
