WARNING
Hydraulic systems are under pressure
Oil can start to flow through the FCU as soon as the

TIP
The return-line connection (OUTLET) must never be obstructed or closed off!
We recommend filling the FCU before measurement. This ensures immediate and accurate
measurements results. It takes approximately 120 ml of oil to completely fill the hydraulic
circuit inside the FCU and INLET hose.
If the FCU is not pre-filled, an air-oil mixture will flow through the FCU at the start of
measurement. The sensor will interpret the air bubbles as particles, thereby falsifying the
measurement result.
For the first sampling without pre-filling the FCU and hoses, we recommend using at least
300 ml of fluid.
If the FCU is inadvertently connected to overly high pressure, the excess oil is directed to the
OUTLET port.If the FCU is inadvertently connected to overly high pressure, the excess oil is
