If you have carried out a single point adjustment, this is the entered
value.Withatwo-pointadjustment,thisisthecalculatedvalue.
The value is an indication for the reliability and non-repeadability of
theswitchingpoint.
Thegreaterthedierenceinthepulseratebetweencoveredand
uncoveredstatus,thegreaterthedierentialvalue(DeltaI)andthe
more reliable the measurement. The automatically calculated damp-
ing is also oriented around the Delta I value. The higher the value, the
lowerthedamping.
ADeltaIvaluebelow10%isanindicationforacriticalmeasurement.
In this menu item you can simulate measured values via the signal
output.Thisallowsthesignalpathtobetested,e.g.throughdown-
stream indicating instruments or the input card of the control system.
Note:
Tocarryoutasimulationwiththedisplayandadjustmentmodule,
youhavetoswitchonthesimulationswitchontheelectronicsmodule
(switchposition1).
Youcanndtherotaryswitchontheelectronicsmoduleintheelec-
