CALIBRATION PROCEDURES

7.4. Automatic Zero/Span Cal/Check (AutoCal)

The AutoCal system allows unattended periodic operation of the ZERO/SPAN valve
options by using the M300E's internal time of day clock. AutoCal operates by
executing SEQUENCES programmed by the user to initiate the various calibration
modes of the analyzer and open and close valves appropriately. It is possible to
program and run up to 3 separate sequences (SEQ1, SEQ2 and SEQ3). Each
sequence can operate in one of 3 Modes, or be disabled.
MODE NAME
Disabled

For each mode there are seven parameters that control operational details of the
SEQUENCE. They are:
Attribute Name
Timer Enabled
Starting Date
Starting Time
Delta Days
Delta Time
