Setting of the display range (RANGE)
pressure is displayed in bar.
pressure is displayed in psi.
pressure is displayed in mpa.
when shifting between bar, psi or mpa,
the eds 3000 converts the switching point
settings into chosen unit automatically.
Display range can be defined by the user.
if this setting is selected, then decimal
places and higher and lower display range
must also be set (see below).
example: if display range has
been altered to 0..215.5,
the display value 215.5
corresponds to the nominal
pressure of the unit.
application: display of other units
which are proportional
to the pressure, e.g. kn, kg.

Analogue output (Output)
the analogue output provides
a 4..20 ma signal
the analogue output provides
a 0..10 v signal
calibration of sensor zero point (calibrate)
the actual pressure is saved as
the new zero point.
this is possible in the range
+/- 3% of the unit's nominal pressure.
appears in the display when a
calibration is carried out
in the permissible range
otherwise is displayed.
this function is useful, for example,
if there is always a residual pressure in the
system which should be displayed as 0 bar.
warning:
following a zero point adjustment, for example,
on a 600 bar unit, a pressure of up to 18 bar will
be displayed as 0 bar. before any work is carried
out on the hydraulic system, ensure that the
system is de-pressurised.
