Please refer to my message vom June 18th. First of all P4 has to be adjusted
for exact 1.00V jumps of the outputs independent of the exact input voltages
(e.g. with an A-176 as continuous CV source). Not until the output scale is
adjusted the input scales have to be adjusted (P1, P2) so that an 1V jump at
the corresponding input generates the 1V changes at the outputs.
