Now, it’s necessary calibrate the voltage value nearest to zero using the following trimmers:
P1 for VF
P5 for IG1
P2 for IF
P6 for VG1
P3 for VA
P7 for IG2
P4 for IA
P8 for VG2
For reading the voltage values using always the multimeter with the negative connected to
ground and the positive connected to relative test point in according to the value that you
want calibrate.
Because of the various tube type on which can be connected this card, can happen that the
voltages measured, can be both positive and negative, but it’s always necessary to have a
positive voltage on the test point output. To obtain this, it is necessary to intervene moving
some couple jumpers on the card on the ground of the negative value of the measure.
