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

}, 25

kPa {2500 mmH2O}

Accuracy: ±0.05% of F.S.

Requires air pressure

supply.

Dead weight gauge tester 25 kPa {2500 mmH2O}

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 difculties in calibration to this level in the eld. For calibration to the 0.1% level, contact Yokogawa

representatives from which the instrument was purchased or the nearest Yokogawa ofce.
