5.5 Simulation mode
Normal operation and diagnostic function (warnings and alarms) can be simulated
based on freely selected parameters using this function�
►
Set the requested duration of the simulation with [S�Tim]�
►
Set a simulation value for the measuring element or select the simulation of a
fault of the measuring element with [TEMP]�
►
Set a simulation value for the reference element or select the simulation of a
fault of the reference element with [REF_TEMP]�
►
Write values to the unit�
►
Click on [Start simulation]�
> The simulation runs for the duration set under [S�Tim]�
►
Click on [Stop simulation] to abort the simulation�
