Pipeline
pressure
Used if Current input or
External value is selected
from Pipeline pressure mode.
The pipeline pressure value used
by the dew point calculation based
on the Pipeline pressure mode
setting. Current input is the value
from the selected I/O slot 1 to n.
External value is the value set from
the Modbus fieldbus. See Modbus

7.8 Setting peak tracking
The peak tracking submenu controls the software utility that keeps the laser scan centered on the absorption peak.
Under some circumstances, the peak tracking function can get lost and lock onto the wrong peak. If the system alarm
displays, the peak tracking function should be reset.
