Note concerning setting the FST diagnostic

parameters

−

The 'Ramp time (increasing)' must be

greater than the corresponding value for

'Min. transit time CLOSED' (Code 41)

determined during initialization.

−

The 'Ramp time (decreasing)' must be

greater than the corresponding value for

'Min. transit time OPEN' (Code 40) de

termined during initialization.

−

The 'Sampling time' must not be lower
than the indicated 'Recommended min.
sampling time'. The 'Recommended min.
sampling time' is calculated from the 'Ex

pected duration of test'.
