Application: Calibration of a pressure gauge with accuracy 1,0%.

As reference item there is a CPH 6200 with 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.

The values of measurement points will be defined

automatically. The generation of these points are

influenced by the range and accuracy of the test

item.

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.

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.
