Select a manometer having
a pressure range close to
that of the transmitter.
Pressure
generator
Model MC100 pneumatic pressure standard for 200 kPa {2 kgf/cm 2 }, 25
kPa {2500 mmH 2 O}
Accuracy: ±0.05% of F.S.
Requires air pressure
supply.
Dead weight gauge tester 25 kPa {2500 mmH 2 O}
Accuracy: ±0.03% of setting
Select the one having a
pressure range close to that
of the transmitter.
Pressure
source
Model 6919 pressure regulator (pressure pump)
Pressure range: 0 to 133 kPa {1000 mmHg}
Prepare the vacuum pump
for negative pressure
ranges.
Note: The above table contains the instruments capable of performing calibration to the 0.2% level. Since special maintenance and
management procedures involving traceability of each instrument to higher-level standards are required for calibration to the 0.1%
or higher level, there may be difficulties in calibration to this level in the field. For calibration to the 0.1% level, contact Yokogawa
representatives from which the instrument was purchased or the nearest Yokogawa office.
