Introduction
The 719 30G and 100G Series Pressure Calibrators (the
Calibrator) perform the following functions:
• Calibrate P/I (pressure to current) transmitters
• Calibrate I/P (current to pressure) devices
• Identify the set, reset and deadband of of pressure
switches
• Measure pressure via a 1/8-in. NPT pressure fitting
and an internal pressure sensor or via a Fluke 700
Series Pressure Module
• Source pressure via electric pump
• Measure, source, and simulate current up to 24 mA
• Simultaneously displays pressure and current
• Supply loop voltage
• Calculate mA percentage in Percent Mode
• Calculate mA error % in Percent Error Mode
• Switch between pressure/vacuum control
The Calibrator features:
• Precision air bleed for fine control
• Fine vernier adjustment for the pump
• A serviceable electric pump
• Pressure limit settings
• HART resistor mode
The Calibrator ships with:
• holster
• two installed 9 V alkaline batteries
• TL75 test leads
• AC70A alligator clips
• hose kit
• Product Overview Manual
• CD-ROM (Users Manual)

719 Series
Users Manual
The Calibrator makes 5-digit pressure measurements in
the units shown below:
• Psi
• inH2O at 4 °C
• inH2O at 20 °C
• kPa
• cmH2O at 4 °C
• cmH2O at 20 °C
• bar
• mbar
• kg/cm2
• inHg
• mmHg
For pressure modules, full-scale readings for all pressure
ranges can be made in:
• Psi
• kPa
• inHg
To avoid display overflow, full scale readings are limited
to 1000 psi in cmH
3000 psi in inH
be measured for meaningful readings in bar and kg/cm
O, mbar, and mmHg units, and
2
O units. Pressures of at least 15 psi must
2
2
units.

Safety Information
A Warning identifies conditions and actions that pose
hazard(s) to the user; a Caution identifies conditions and
actions that may damage the Calibrator or the equipment
under test. Symbols used in this manual and on the
Calibrator are listed in Table 1.
XWWarning
To avoid possible electric shock or personal
injury:
• Use the Calibrator only as specified in
this manual, otherwise the protection
provided by the Calibrator may be
impaired.
• Never apply more than 30 V, including
transients, between the mA terminals, or
between either of the mA terminals and
earth ground.
• The Calibrator is rated for CAT I
measurement only. Do not use the
Calibrator to make measurements in a
CAT II, CAT III, or CAT IV environments.
CAT I equipment is designed to protect
against transient from high-voltage, lowenergy sources, such as electronic
circuits or a copy machine
• Remove the test leads from the
Calibrator before opening the battery
door.
Pressure Calibrator with Electric Pump
Introduction
• Make sure the battery door is closed and
latched before operating the Calibrator.
• Do not operate the Calibrator if it is
damaged.
• Do not operate the Calibrator around
explosive gas, vapor, or dust.
• When using probes, keep fingers behind
the finger guards on the probes.
• Use only two 9 V batteries, properly
installed in the Calibrator case, to power
the Calibrator.
• Follow all equipment safety procedures.
• Turn off circuit power before connecting
the Calibrator mA and COM terminals in
the circuit. Place Calibrator in series with
the circuit.
• When servicing the Calibrator, use only
specified replacement parts.
• Do not allow water inside the case.
• To avoid false readings, which could
lead to possible electric shock or
personal injury, replace the battery as
soon as the battery indicator (B)
appears.
• To avoid a violent release of pressure in
a pressurized system, shut off the valve
and slowly bleed off the pressure before
attaching or detaching the internal
pressure sensor or pressure module
fitting to the pressure line.
• To avoid over pressure damages, do not
apply pressure that exceeds the limits
listed in the Pressure Specifications
table in the Specifications section.
• To avoid mechanically damaging the
Calibrator, do not apply torque between
the pressure fitting and the Calibrator
case. See Figure 1 for the proper use of
tools.
• To avoid misleading readings,
disconnect the pressure module
connector at the Calibrator.
• To avoid damage to the pressure
module, refer to the related Instruction
Sheet.
• To avoid damage to the pump, use with
dry air and non-corrosive gases only.
• Check test leads for continuity before
using. Inspect Calibrator for cracks or
damage, do not use the probes if they
are damaged or show high resistance.
