A deadweight tester is a proven
method of pressure calibration
that is usually chosen for bench
applications when accuracy
and reliability are the top
requirements. Calibrations are
performed at the bench for
convenience and to maintain
reference conditions. The bench
is a convenient location to clean,
inspect, calibrate and repair with
all the necessary equipment
available. Reference conditions
are necessary to achieve the
reference accuracy of the device
under test and the calibration
standards. Reference accuracy
may be required to maintain
the necessary test uncertainty
ratios (TUR).
