Table 6- 41 OXYMAT 7: Application 5
Description of application 5
Conditions
• The interference gas concentration is variable.
• The influence of the interference gas is not known and will be determined by the wizard.
Sequence
• Selection of measured value source for the interference gas.
The interference gas is measured in the selected unit.
• Enter substitute value in the selected interference gas unit: If the measured value of the inter-
ference gas concentration is invalid or not available, the device works with the concentration
of the substitute value.
• Determine the correction coefficient k1 by means of a measuring sequence. Enter the set-
point required in the measurement procedure in the unit of the sample gas.
Result The influence of the interference gas is determined from the measured sample gas concentration
and the applied interference gas with the specified setpoint.
• Case 1: The interference gas concentration is measured and is valid.
• Case 2: The interference gas concentration cannot be measured or is invalid.
ULTRAMAT 7 application scenarios
Table 6- 42 ULTRAMAT 7: Application scenario 1
Description of application scenario 1
1)
Conditions
• The interference gas concentration is known and is assumed to be constant.
• The influence of the interference gas is known
Consequences
• Enter the constants in the unit of the measured value.
Result The specified constant is subtracted from the measured value.
1)
Corresponds to application scenario 2 with OXYMAT 7
