Associate More Than One Set of Profi les to a Specifi c Model

Imagine, for example, you have a number of Nuova Fima EN837-1 40 Bar gauges and some require a standard nine-point calibration but others, because

of the task that they perform, require a fi ner 17-point calibration. In this case you would create two models, identical except that they would have diff erent

names, such as EN837-1 Coarse and EN837-1 Fine, and diff erent calibration profi les associated with them.

CALIBRATION STRATEGIES

The following discussions provide detailed instructions for getting through a calibration using the various modes and approaches available with FastCalXP.

These discussions also provide information which should help you to establish your own protocol for pressure gauge calibration.

Regardless of the protocol that you settle on, practice will improve your speed and accuracy. Take your time and do not hesitate to retrace your steps. A cali-

bration is only fi nalized when it is saved following completion of the profi le.

Exercising

Exercising the gauges prior to completing a calibration may improve the accuracy of the calibration. Exercise the gauges by applying the full scale pressure of

the gauge one or more times. Refer to the

GaugeCalHP Operation Manual

for a more detailed discussion of exercising the gauges.

FastCalXP provides an Exercise Window to encourage completion of exercise cycles prior to a calibration. The number of exercise cycles is associated with the

profi le and specifi ed in the Profi les editor.
