3-8 Operation Rosemount Analytical Inc. A Division of Emerson Process Management
Model CAT100
Entry of 0: Spanning without cross-
compensation correction (test gas mix-
ture)
Entry of 1: Spanning with cross-
compensation correction (pure test
gases)
Use the INPUT-CONTROL pads to
change the value and then activate
ENTER.
To perform a calibration with cross-
compensation:
•
First perform a zeroing for both chan-
nels.
•
Then perform a spanning for both
channels
•
Then repeat the spanning for the first
analysis channel
NOTE
Both cross-compensation and
cross-compensation calibration
must be enabled in order to perform
a correct calibration with cross-
compensation correction! Use only
pure test gases!
NOTE
When using test gas mixtures,
“C.Cal” must be set to zero!
d. Hold
The Hold function permits keeping the
analog output signals and the concen-
tration limits locked at the last meas-
ured values during a calibration
procedure.
Entry of 0: The outputs remain unlocked
Entry of 1: The outputs will be locked
during a calibration
Use the INPUT-CONTROL pads to
change the value and then activate
ENTER.
e. Automatic
Calibration
This function enables or disables auto-
matic-calibration when the analyzer is
equipped with the optional internal or
external solenoid valves. Digital outputs
are also enabled.
Entry of 0: The outputs remain unlocked
Entry of 1: The outputs will be locked
during a calibration
Use the INPUT-CONTROL pads to
change the value and then activate
ENTER.
f. Tolerance
Check
The Tolerance function is for the activa-
tion and deactivation of the tolerance
check procedure for various calibration
gases. If the tolerance check procedure
has been activated, during a calibra-
tion, the analyzer will indicate if the
calibration shows a deviation of more
than 10% from measuring range of zero
or more than 10% of the nominal con-
centration value of span.
If this tolerance is exceeded, no calibra-
tion will be performed and an error
message will appear.
Entry of 0: Tolerance check is deacti-
vated
