The settings of the minimum and maximum voltages interact with each other. This check must be repeated
at least three times to check the correctness of the values to be obtained.
4)Activating again the unit with code "AA": a voltage of 100V (± 2V) should be obtained together with the
following wave form on TP “F”:

5)Set function “bipolar PC” and code "FF", activate the device and calibrate the R4 pot to obtain a
continuous voltage of 150V (± 2V) on VREG.
6)Activate again the device with code "FE" and calibrate the R13 pot to obtain a continuous voltage of 3V
(±0,1V) on VREG and the following wave form on TP “F”:
