Mode of operation
If the flow of sample is interrupted, the pressure monitor reports this status to the computer (DI = 1)
via the switch input DI5.
This causes the device to respond as follows:
• All the pumps are stopped.
• Pump P2 is drained.
• The strip chamber is rinsed.
• The current output is set to 0.0 mA.
• The analyzer operates without displaying a measured value.
The device resumes measuring operation automatically as soon as sample flows again.
