Screenshot demo-version of a calibration
procedure with software EasyCal
EasyCal calibration assistant will lead in 6
steps through the calibration. There are 2
different possibilities of a calibration with
EasyCal.

• Fully-automated computer aided calibration of
  pressure transmitters with EasyCal. (The
  Pressure controller CPC 8000 automatically
  generates the pressure values given by EasyCal.
  Both measurement values will be given
  by EasyCal imported to EasyCal and
  evaluated.)

• Semi-automated computer aided calibration of
  pressure gauges with EasyCal. (The pressure
  values have to set via a pressure source
  (test pump) acc. to the display of the test
  item and confirmed by a mouse-click.)

Semi-automated computer aided calibration of
pressure gauges with EasyCal
Application Calibration of a pressure gauge with
accuracy 1,0. As reference item there is a CPH
6200 with accuracy 0,2.
Interface cable
Test item accuracy 1,0
Test-pump to generate pressure
Calibration item accuracy 0,2

Semi-automated computer aided calibration of
pressure gauges with EasyCal
General A calibration is done by a direct
comparison between the measured values of the
calibration object (test item) and those of the
reference or working standard, which is directly
or indirectly traceable to a national
standard. Calibration procedure The pressure
values of the Test Cycle will be calculated by
the Software EasyCal. Each time the recommended
pressure value has to be set via a pressure
source (test pump) acc. to the display of the
test item. (Notice the pressure should not
over-shoot to detect the hysteresis of the test
item) . Is the respective pressure set, user
informs the software via a mouse-click/Enter-key
and the value of the reference/CPH 6200 is read
in via the RS-232/USB interface and stored next
to the recommended pressure value, which is
currently shown by the test item. After all
pressure values are likewise produced the
software automatically do the evaluation
(calculation of uncertainty and hysteresis),
stores the data in an ACCESS-Databank and a
printable Certificate is produced, which can be
designed by the user (own Logo, etc). if
needed the recommended pressure values can be
changed.

1.) Fully-automated computer aided calibration of
pressure transmitters with EasyCal.
Up to the 5. step (the calibration procedure),
the fully-automated calibration runs analog to
the semi-automated procedure, but the set values
are generated automatically by the pressure
controller and the measurement values are
stored.The calibration report is also created
automatically.

1.) Fully-automated computer aided calibration of
pressure transmitters with EasyCal.
Pressure supply (110 FS)
Test item
multimeter (with shunt)
PC with EasyCal
IEEE-interface cable
CPC 8000
Calibration procedure The CPC 8000 will control
automatically all pressure steps (one after
another), recommended / calculated by the
Software EasyCal. Is one pressure controlled and
stable the software will read the signal of the
test item via the multimeter and will give the
signal to start to control the next
pressure. After all pressure values are likewise
produced the software automatically do the
evaluation (calculation of uncertainty and
hysteresis), stores the data in an
ACCESS-Databank and a printable Certificate is
produced.

3.) The calibration item does not match the
calibration class
The calibration item does not match the
calibration class of 1. It has a tolerance of
1.1. The calibration has to be stopped and the
calibration item has to be adjusted.After
adjustment, the calibration item can be
calibrated again.
