6.9.6.2
Assigning variable correction of cross-interference
Procedure with OXYMAT 7
1. Component > Main menu > "2. Settings" > "10. Correction of cross-interference" > "3 ... 6
..."
2. Enable/disable correction of cross-interference: "Correction of cross-interference"
parameter field.
Authorize access with corresponding PIN, if necessary.
The correction of cross-interference is activated/deactivated for a specific correction
value.
3. Select source for correction value: "Source of correction value" parameter field
The following sources can be set for the correction of cross-interference:
– "Device-internal"
– "MODBUS TCP"
– "Analog input" (with installed option module 2)
NOTICE
Malfunction of the device with correction of cross-interference via an analog input
The following applies to prevent the device from malfunctioning: Make sure that the
correction gases in → menus "2.10.3" to "2.10.6" and "2.09.1.n" match. For additional
information, see also → Set analog inputs (Page 137).
Depending on the set parameter value, there will be different operating steps:
Source of correction value
"Device-internal"/"Analog input"
"MODBUS TCP"
• Select an internally measured correction value.
"Component" parameter field.
The selection list contains all existing compo-
nents of the device except the respective cur-
rent measured component.
• Determine external analyzer which de-
livers the correction value via
MODBUS TCP.
"MODBUS node" parameter field
• Enter substitute value for the measured inter-
ference gas concentration.
"Substitute value" parameter field.
If the measurement of the interference gas con-
centration fails, the set substitute value is used
for the correction of cross-interference.
The measured value status is set to "Uncer-
tain".
The unit of the substitute value corresponds to
that of the configured interference gas.
• Select external measured correction
value for correction of cross-interference
via MODBUS TCP.
"Measured value" parameter field.
