Product technial information：

Proper functioning of the transformers and sensors is important for proper functioning 

of the REF542plus. The measured-value processing of the unit and the set rated values

 must be tested for this reason. 

The phase currents and phase voltages must be taken as measured input quantities. 

All other measured values are quantities derived from them. 

Test as follows: 

Check whether the set rated values match the rated values required by the user (in 

the order documentation). 

If necessary, load the application into the PC from the REF542plus. 

Select the menu item Main Menu/Settings/Connections/Analog Inputs in 

the configuration program. The rated values are shown in the dialog window that appears

 and, if necessary, changed. 

Test the wiring of the transformers or sensors 

Disconnect the transducers or sensors from the REF542plus. 

The current transformers must be short-circuited, combination sensors disconnected. 

Connect the test set to the REF542plus. The relevant current and voltage signals are applied to the analog inputs. Set the required rated values on the test set
