Fluke Calibration 719 is an electric pressure calibrator designed for fast, accurate and convenient calibration of pressure transmitters, pressure switches, I/P converters and other process instrumentation. Its defining feature is the integrated electric pressure pump, which allows pressure to be generated at the push of a button and enables true one-handed pressure calibration in the field.

The Fluke Calibration 719 combines pressure generation, pressure measurement, mA measurement and sourcing, and a 24 V loop power supply in one compact handheld instrument. Current models are available for 30 psi and 100 psi pressure ranges, while the internal pressure measurement provides an accuracy of 0.025% of range for six months. For applications outside the internal range, compatible Fluke 750P pressure modules considerably expand the measurement capability. Fluke

Unlike a calibrator that requires a manual pressure pump, the motorized pump of the Fluke Calibration 719 generates pressure automatically. Programmable pump limits help prevent accidental overpressure and allow target pressures to be defined. Fine pressure adjustment is supported by a precision vernier and a variable-rate bleed valve, making the instrument particularly practical for accurate transmitter calibration. Fluke

The integrated pump minimizes the amount of separate equipment that technicians need to carry. Fluke specifically positions the 719 for quick pressure calibration and process maintenance using its electrically driven pump. Fluke

Integrated Electric Pressure Pump

The major difference between the Fluke Calibration 719 and conventional handheld pressure calibrators is its built-in electric pump.

Instead of repeatedly operating a manual hand pump, the user can generate the required test pressure electrically.

This provides several practical advantages during field calibration:

• Less manual pumping
• Faster pressure generation
• Easier one-handed operation
• More convenient repeated calibration points
• Reduced effort when calibrating multiple instruments

For the 100 psi version, Fluke specifies a maximum pump pressure generation of 120 psi / approximately 8 bar. Fluke

The electric pump makes the 719 especially attractive for technicians who regularly calibrate pneumatic pressure transmitters at different locations.

Two Internal Pressure Ranges

The Fluke Calibration 719 is available in two principal configurations.

Fluke Calibration 719 30G

The 719 30G is intended for applications around the 30 psi range.

Fluke specifies:

Range: -12 to 30 psi

Metric range: approximately -850 mbar to 2.4 bar

Resolution: 0.001 psi / 0.1 mbar

6-month accuracy: 0.025% of range

1-year accuracy: 0.035% of range. Fluke

Fluke Calibration 719 100G

The 719 100G is designed for higher pneumatic pressure applications.

Fluke specifies:

Range: -12 to 100 psi

Metric range: approximately -850 mbar to 8 bar

Resolution: 0.01 psi / 1 mbar

6-month accuracy: 0.025% of range

1-year accuracy: 0.035% of range. Fluke

This allows users to select an internal measuring range appropriate for the pressure transmitters and switches they most frequently calibrate.

Pressure Accuracy of 0.025%

The Fluke Calibration 719 provides an internal pressure accuracy of:

0.025% of range for six months.

For a one-year calibration interval, the specification is:

0.035% of range. Fluke

A clearly defined pressure accuracy is essential when the 719 is used as the pressure reference during transmitter adjustment or pressure-switch testing.

The correct model should be selected so that the internal measuring range is appropriately matched to the device under test.

Measure and Source mA

The Fluke Calibration 719 does more than measure pressure.

It can both measure and source current, making it particularly useful for process instrumentation.

The electrical range is:

0 to 24 mA

with a resolution of:

0.001 mA.

The specified accuracy is:

0.015% of reading + 2 counts. Fluke

This capability allows the 719 to work with the standard 4–20 mA signals widely used by industrial pressure transmitters, valves and I/P converters.

Pressure Transmitter Calibration

A typical pressure transmitter converts an applied pressure into a 4–20 mA electrical signal.

The Fluke Calibration 719 provides several functions required for such a calibration in one device:

• Generates the pneumatic pressure
• Measures the applied pressure
• Supplies 24 V loop power
• Measures the transmitter output current

This considerably simplifies a typical field calibration setup.

Instead of using a separate pressure generator, reference pressure gauge, loop supply and current meter, the 719 combines the central functions in one portable calibrator.

Integrated 24 V Loop Power

The Fluke Calibration 719 provides an integrated:

24 V DC loop supply.

Fluke specifies the loop supply with an accuracy of ±10%. Fluke

The loop supply allows compatible two-wire transmitters to be powered during testing.

This is especially practical when the transmitter has been isolated from the plant control system or is being tested on a bench.

I/P Converter and Valve Testing

Because the Fluke Calibration 719 can source mA, it can also be used for testing devices that convert an electrical signal into a pneumatic response.

Fluke specifically identifies valves and I/P converters as applications for the mA source function. Fluke

The user can generate a defined current signal and evaluate how the connected process component responds.

This expands the 719 beyond pure pressure-transmitter calibration and makes it a useful process troubleshooting instrument.

Programmable Pump Limits

The electric pump provides programmable pressure limits.

This feature can help:

• Prevent accidental overpressure
• Protect sensitive pressure instruments
• Define suitable operating limits
• Improve repeatability during routine calibration

The operator can also program target pressure values for the pump. Fluke

This provides greater control than simply switching an electric pump on and off.

Precision Pressure Adjustment

Once the pressure is close to the desired calibration point, precise adjustment becomes important.

The Fluke Calibration 719 therefore includes a:

precision pressure adjustment vernier

for fine setting of the pressure. Fluke

This allows the operator to approach the desired calibration point more accurately after the electric pump has generated the basic pressure.

A variable-rate bleed valve additionally supports controlled pressure reduction.

Pressure Switch Testing

The Fluke Calibration 719 incorporates a dedicated pressure-switch test function.

This enables the user to determine the switching behavior of pressure switches without requiring separate measurement equipment.

The instrument is therefore suitable for checking pressure switches during:

• Preventive maintenance
• Commissioning
• Troubleshooting
• Periodic calibration
• Laboratory testing

Fluke explicitly includes pressure-switch testing among the standard functions of the 719. Fluke

Easy-to-Clean Pump System

Contamination is an important consideration for portable pressure calibrators.

Moisture or process fluids can enter a pneumatic calibration system and affect the pump.

The Fluke Calibration 719 therefore incorporates dedicated pump cleanout ports. Fluke states that this design helps reduce pump failures caused by moisture and fluid contamination and allows the pump system to be cleaned more easily. Fluke

This is especially valuable for instruments used regularly in industrial field service.

Extended Pressure Measurement with Fluke 750P Modules

The internal sensor does not limit the Fluke Calibration 719 to only its 30 psi or 100 psi range.

Fluke states that the 719 supports external 750P Series pressure modules, significantly extending its pressure measurement capability. Fluke

The current 750P family includes high-pressure modules such as:

750P29: up to 200 bar

750P30: up to 340 bar

750P31: up to 700 bar / 10,000 psi. Fluke

This modular concept enables the 719 to cover a much wider range of pressure-measurement applications when an appropriate external pressure source is used.

The electric pump inside the 719 does not generate 700 bar. The extended range refers to measurement using an external pressure module and a suitable external pressure source.

Compact Handheld Design

The Fluke Calibration 719 is designed for mobile field use.

Fluke specifies dimensions of approximately:

60 × 87 × 210 mm

and a weight of approximately:

912 g. Fluke

The compact format allows the complete instrument to be carried conveniently between different measurement locations.

A protective yellow holster provides additional protection during industrial service work.

Battery-Powered Operation

The Fluke Calibration 719 operates from:

two 9 V alkaline batteries.

Under the test conditions stated by Fluke, battery life is approximately 12 hours, including transmitter current operation and defined pump cycles. Fluke

Battery operation means that the instrument does not require a mains connection during mobile calibration work.

Environmental Specifications

The specified operating temperature range is:

-10 °C to 55 °C.

The storage temperature range is:

-30 °C to 60 °C.

Fluke also specifies a 1 m drop test, supporting the intended use of the instrument as a rugged portable process calibrator. Fluke

Pump Lifetime

For the integrated electric pump, Fluke specifies:

5,000 pump cycles between rebuilds

and a total pump life of:

20,000 calibration cycles. Fluke

The cleanout-port concept is intended to help reduce failures caused by moisture and contamination and thereby support reliable operation in field applications.
