8. Place the processor in the TEST or PROG mode.
9. Output full scale (+10V) either with write block transfer data or
by placing the LAST STATE configuration jumpers in the MAX
position.
10.Adjust R66 until the reading is 10V +1mV.
11. Output -10V either with write block transfer data or by placing
the LAST STATE configuration jumpers in the MIN position.
12.Adjust R67 until the reading is one-half the difference between
-10V and the initial reading.
13.Output full scale (+10V) again, either with write block transfer
data or by placing the LAST STATE configuration jumpers in the
