6.7 Measuring pressure

For pressure calibration, connect the calibrator with an appropriate adapter. Select the

pressure setting for the display being used. The calibrator is equipped with one or two

internal reference pressure sensors.

Choose a sensor that is suitable for the pressure range and accuracy.

CAUTION!

Pressure sensors may be damaged and/or injuries may occur to

the personnel due to improper application of pressure. For a better

understanding with respect to overpressure and burst pressure, follow

the specications laid down in these operating instructions (see chapter

3 "Specications"). Vacuum should not be applied to any gauge pressure

sensor.

The calibrator display will indicate "OL" when an inappropriate pressure

is applied. As soon as "OL" is observed on any pressure display, the

pressure should be reduced immediately to prevent damage or possible

physical injury. "OL" is displayed if the pressure exceeds 110 % of the

nominal range of the sensor or if a vacuum in excess of 140 mbar (2 psi)

is applied on a gauge pressure sensor.
