Pressure Calibrator
Introduction
The Fluke Model 718 30G and 718 100G Pressure
Calibrators (hereafter called “Calibrator”) can do the
following:
• Calibrate P/I (pressure to current) transmitters.
• Measure pressure via a 1/8-inch NPT pressure fitting
and an internal pressure sensor or via a Fluke 700
Series Pressure Module.
• Measure current up to 24 mA.
• Simultaneously display pressure and current
measurements.
• Supply loop voltage.
The Calibrator makes 5-digit pressure readings in the
following units: psi, inH
2
O at 4 °C, inH
2
O at 20 °C, kPa,
cmH
2
O at 4 °C, cmH

O at 20 °C, bar, mbar, kg/cm

, inHg,
and mmHg. Full scale pressure sensor input is as follows:
• Model 718 30G: 30 psi (206.85 kPa, 2.0685 bar). “OL”
appears at 33 psi.
• Model 718 100G: 100 psi (689.5 kPa, 6.895 bar). “OL”
appears at 120 psi.
The Calibrator measures pressure sensor inputs in the
units shown in Table 1.
For Pressure Modules, full scale readings for all pressure
ranges can be made in psi, kPa, and inHg units. To avoid
display overflow, full scale readings are limited to 1000 psi
in cmH
2
O, mbar, and mmHg units, and 3000 psi in inH
2
O
units. Pressures of at least 15 psi must be measured for
meaningful readings in bar and kg/cm
2
units.
