KROHNE SU 600 EN - Manual (Page 23)

Scaling is the conversion of the measured value into a
certain parameter or measuring unit. Instead of the
percentage value, the volume can be displayed, e.g. in l.
Indicating values between max. -9999 and +9999 are
possible.
à
First of all, determine the max. indicating range and
the number of decimal places after the decimal point
-- max. four decimal places can be displayed. Select
position [ 5 ] of the function switch, place the decimal
point in the required position and save your settings.
à
Now select position [6] or [7] on the function switch,
enter the requested values for 100 % or 0 % and
save your settings.
To suppress fluctuation in the measured value display,
e.g. caused by an agitated product surface, an integra-
tion time can be set. This time can be between 0 and
250 seconds. Keep in mind that this setting will increase
the reaction time of the measurement, and that the
reaction to quick changes of the measured value will be
delayed. In general, a time of a few seconds is sufficient
to smooth the measured value display.
à
Now select position [9] on the function switch, enter
the requested value and save your settings.
The characteristics of the current output can be
switched over from 4 … 20 mA to 0 … 20 mA.
à
Now select position [8] on the function switch, adjust
the requested characteristics curve and save your
settings.
To check if the settings ofSU 600 are correct, the
simulation mode can be used. Any individual measured
value can be simulated and e.g. the correct behaviour of
the relays and the connected instruments can be
checked.
Switching over between the functions "OPERATE" and
"Simulation" is done by pushing the [+/-] keys for at least
3 seconds.In the simulation mode, the set value flashes
on the display. The simulation can be switched off by
