12.For the start of scale value 0 bar, check the zero point (4 mA).
If the differential pressure lines ⑤ have equally high condensate columns with the same
temperature, the measurement result is error-free. Otherwise, repeat the zero-point
adjustment.
13.Close the stabilizing valve ②.
14.Fully open the differential pressure valves ③ and ④.
Cleaning process cable
1. To clean the line, briefly open the drain valves ⑦.
