32 SEC ( Filter Factor 32 seconds )
default setting: 2 SEC Also see jump out in section 4.2.2.11
4.2.2.11 JP out ( Filter jump out )
This sets the change in input value, expressed as a percentage of full scale, below
which the filter operates and above which the filter is inoperable. This enables the
indicator to respond quickly to large changes, whilst filtering smaller noisy signals.
The diagram below shows the operation of the Jumpout on a filtered input. Each of
the waveforms is based upon the same raw input 'A'. By setting the Jumpout band
just greater than the noise level; the filtering is switched off for any change in actual
signal. In this way, a compromise between heavy filtering and signal response can be
reached.
The following options are available:
nonE ( No jump out, filter in operation all of the time)
1 PEr ( Jump out band, 1% of engineering range )
5 PEr ( Jump out band, 5% of engineering range )
