Chapter 4 Calibration in Different Pressure Units Introduction The deadweight tester can be used to calibrate in different pressure units in either of two methods. Conversion Weights A set of Conversion Weights can be supplied, marked in the required pressure unit, and adjusted to the correct mass for use with the existing piston(s). The set includes (where applicable) a replacement low-pressure weight carrier table, and a replacement high-pressure weight carrier ring. These items are simply exchanged for the original items when using the conversion weights. Calibration is carried out as described above, with logical pressure increments throughout the operating range, avoiding the need to perform pressure unit conversion calculations. Software PressCal software is available for use with deadweight testers, and will allow users to apply all necessary corrections (e.g. local gravity, temperature, pressure head, etc.) to enhance the pressure measurement accuracy of the instrument. It will allow calibration in any of 12 different pressure units, using the existing weight set. 4-1 MyFlukeStore Shop for Fluke products online at: www. .com 1.888.610.7664

Chapter 4
Calibration in Different Pressure Units
Introduction
The deadweight tester can be used to calibrate in different pressure units in either of two
methods.
Conversion Weights
A set of Conversion Weights can be supplied, marked in the required pressure unit, and
adjusted to the correct mass for use with the existing piston(s).
The set includes (where applicable) a replacement low-pressure weight carrier table, and
a replacement high-pressure weight carrier ring. These items are simply exchanged for
the original items when using the conversion weights. Calibration is carried out as
described above, with logical pressure increments throughout the operating range,
avoiding the need to perform pressure unit conversion calculations.
Software
PressCal software is available for use with deadweight testers, and will allow users to
apply all necessary corrections (e.g. local gravity, temperature, pressure head, etc.) to
enhance the pressure measurement accuracy of the instrument.
It will allow calibration in any of 12 different pressure units, using the existing weight set.
