Pressure Calibrator
Introduction
The Fluke 718 Series Pressure Calibrators 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
•
Source pressure
• Measure current up to 24 mA
• Simultaneously display pressure and current
measurements.
• Supply loop voltage
• Calculate mA percentage in Percent Mode
• Calculate mA error % in Percent Error Mode
The 718 Pressure Calibrators (hereafter, “the Calibrator”)
include:
• 718 1G
• 718 30G
• 718 100G
• 718 300G
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
2
O at 20 °C, bar, mbar, kg/cm
2
, inHg,
and mmHg.
Pressure sensor specifications are as listed under
“Pressure Sensor Input”.
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.
Your Calibrator is supplied with a holster, two installed 9 V
alkaline batteries, one set of TL75 test leads, one set of
AC70A alligator clips, one 700-ILF In-Line Filter (to protect
the pump), a Product Overview Manual, and a CD-Rom.
If the Calibrator is damaged or something is missing,
contact the place of purchase immediately. Contact your
Fluke distributor for information about accessories. See
