9.4.1  Gauge Output Zero Adjust

Set the gauge display to read "0" (Zero).  Adjust TC Zero (R11 for channel A,  R21 for channel B, or R30 for 
channel C) for exactly 0.00 Vdc on the appropriate TC output.

9.4.2  Gauge Output Full Scale Adjust

Set the gauge display to read 1.0 Torr. Adjust T. C. Full Scale  (R12 for channel A, R22 for channel B, or R31 
for channel C) for exactly 10.0 Vdc on the appropriate TC output.
