Preparing the FCU for measurement
Measuring from unpressurized containers
Required hoses:
To guarantee valid and direct measurements, prime the FCU. To do
this, draw in ≈ 120 ml fluid via the inlet hose in order to completely
fill the hydraulic circuit and the inlet hose.
If the FCU is not primed, an air-oil mixture at the start of
measurement will flow through the FCU. The sensor will interpret
this air-oil mixture as particulate soiling and will thus falsify the
measurement result.
For an initial test without priming the FCU and hoses, you need at
least 300 ml of fluid.
