6-1 SYSTEM CALIBRATION MODES - OVER-
VIEW
System calibration can be established in one
of two modes or disabled.
Interval Operation
Interval calibration allows the setting of an
“Start of interval time” which is the time of day
for the interval calibration to occur, and an
“Interval time” which is the number of hours
between each calibration event in the range of
1 to 10,000.
Interval calibration can perform basic Zero
and Zero/span calibration.
Interval calibration can also be used to estab-
lish and interval for a “Sequence Pro-
grammed” calibration.
Sequence Programming
Sequence calibration programming allows for
the setup of up to 40 program sequences for
various calibration functions of up to 4 bound
Analyzer modules. The programmed se-
quence can be initiated by the “Interval” op-
eration or manually.
Disabled
If Interval and Sequence calibration is dis-
abled, no automatic calibration will occur but
manual calibration can be performed from
each individual bound Analyzer module using
the “Calibration and test procedures” menu.
Calibration Test
The calibration test function allows the testing
of the calibration by flowing gas to an Ana-
lyzer and viewing the results.
Before setting any parameters, make sure the
system clock is set correctly. This is to be
found in Section 6-6, page 6-7.
