49. uation remains the control must be replaced If on the other hand the message disappears the control can still be used When the EE error occurs frequently and or is hard to resolve it is recommended to have the control checked in that the original accuracy may not be guaranteed It is good practice to investigate the cause of this type of error so as to prevent it occurring again We ask to read carefully the chapter INSTALLATION and in particular the paragraphs Special warnings and General warnings installation and connection environments 6 3 1 Loading the default parameters The default values of the parameters can be restored by following the procedure described below e switch the instrument off EA set 2 e press and hold the and buttons and switch the instrument on e the display shows the message followed by CF e after some seconds the instrument will start working with the default configuration Any of the F and C parameters that differ from the default configuration can be modified as desired IMPORTANT WARNINGS e the procedure described above resets the instrument assigning the default value to all the parameters and set points As a result all modifications made to the operating parameters will be lost e given the delicacy of this operation the procedure must be performed by specialist personnel However this procedure does not damage the instrument but rather resets its original purchase configuration s
