3.3.1 Setting up an AUTO-CAL

When proper automatic valving is connected, the Analyzer can cycle itself

Note: Before setting up an AUTO-CAL, be sure you understand the
Zero and Span functions as described in section 4.4, and
follow the precautions given there.
Note: If you require highly accurate AUTO-CAL timing, use external
AUTO-CAL control where possible. The internal clock in the
Model 6600 is accurate to 2-3 %. Accordingly, internally sched-
