Fluke Calibration 718 is a versatile handheld pressure calibrator for testing pressure transmitters, gauges and pressure switches directly in the field or in the calibration laboratory. The instrument combines accurate pressure measurement, mA measurement, 24 V loop power and an integrated pressure pump in one compact device. This combination reduces the amount of equipment required for routine process calibration and makes the 718 particularly suitable for maintenance technicians and calibration professionals.

A major advantage of the Fluke Calibration 718 is the integrated pressure pump. Depending on the selected model, pressure can be generated directly by the calibrator, with versions available up to 300 psi / approximately 20 bar. The pump is designed so that it can be cleaned and serviced in the field without completely disassembling the instrument. Fluke specifically highlights this design as a way to reduce pump damage and maintenance effort when the calibrator is used in industrial environments. Fluke

The internal pressure sensor provides an accuracy of 0.025% of full scale, while the electrical input measures 0 to 24 mA with an accuracy of 0.015% + 1 count. Pressure and current can be displayed simultaneously, making the Fluke Calibration 718 especially useful for testing and calibrating 4–20 mA pressure transmitters. Fluke

For applications beyond the internal pressure range, the instrument supports Fluke 750P Series pressure modules. With these external modules, pressure measurement capability can be extended from very low pressures up to 10,000 psi / 700 bar. Fluke

For professional calibration and metrological traceability, europascal offers pressure calibration services for pressure calibrators, pressure gauges, sensors and other precision pressure instruments. More information is available through the europascal Calibration Service.

Built-In Pressure Pump

One of the defining features of the Fluke Calibration 718 is its integrated pressure pump.

This means that an external hand pump is not normally required for calibration work within the pressure range of the selected 718 model.

The pump allows the technician to generate the test pressure directly from the handheld calibrator. Fluke offers the 718 in several pressure ranges, with internal models extending up to 300 psi / approximately 20 bar. Fluke

This significantly simplifies mobile calibration setups.

Instead of carrying:

pressure gauge + electrical meter + loop supply + pressure pump,

the Fluke Calibration 718 combines these essential functions in one instrument.

Easy-to-Clean Pump Design

Pressure pumps used in industrial service can accidentally come into contact with liquids or contamination.

The pump of the Fluke Calibration 718 is designed for straightforward field maintenance.

Fluke states that the integrated pump can be cleaned and serviced without completely disassembling the calibrator. This design helps protect the pressure system from contamination and can reduce maintenance costs and downtime. Fluke

This feature is especially useful for technicians who perform pressure calibration directly on industrial equipment.

Four Internal Pressure Ranges

The Fluke Calibration 718 family is available in four primary versions.

These ranges allow the appropriate internal sensor to be selected according to the calibration task. Fluke

Using a range that is well matched to the application improves practical measurement resolution and makes the calibrator suitable for different pneumatic process applications.

Pressure Accuracy of 0.025% FS

The internal pressure measurement accuracy of the Fluke Calibration 718 is specified as:

0.025% of full scale. Fluke

This level of performance makes the instrument suitable for professional process calibration, maintenance and troubleshooting tasks.

The individual model ranges also provide different pressure resolutions depending on the full-scale value.

For example, the 718 30G provides a pressure resolution of 0.001 psi, while higher-range models use appropriately scaled resolutions. Fluke

Pressure Measurement up to 700 bar

The internal pressure range can be expanded through optional Fluke 750P Series pressure modules.

Fluke specifies compatibility with pressure modules covering approximately:

2.5 mbar to 700 bar

or:

0 to 10,000 psi. Fluke

This considerably expands the range of applications for the Fluke Calibration 718.

Instead of purchasing separate handheld calibrators for every pressure range, users can connect an appropriate external pressure module.

The exact pressure accuracy, media compatibility and overpressure capability are then determined by the selected pressure module.

mA Measurement for Pressure Transmitters

Many industrial pressure transmitters convert pressure into a standardized 4–20 mA electrical output.

The Fluke Calibration 718 therefore includes a dedicated current measurement function.

The current range is:

0 to 24 mA

with a resolution of:

0.001 mA.

The specified mA accuracy is:

0.015% + 1 count. Fluke

This enables the pressure applied to a transmitter and its electrical output signal to be checked with the same instrument.

Simultaneous Pressure and Current Display

The Fluke Calibration 718 can display pressure and current simultaneously.

This is particularly valuable during pressure transmitter calibration.

A typical calibration setup consists of:

Fluke 718 pressure source → pressure transmitter → mA input

The internal pump generates the test pressure, the internal pressure sensor measures that pressure and the electrical input measures the corresponding transmitter output.

This integrated approach reduces setup time and minimizes the number of separate instruments required.

Integrated 24 V Loop Power

The Fluke Calibration 718 also provides:

24 V DC loop power. Fluke

This allows a two-wire pressure transmitter to be powered directly by the calibrator.

For a typical 4–20 mA pressure transmitter test, the Fluke 718 can therefore provide:

• Pressure generation
• Pressure measurement
• 24 V transmitter supply
• mA measurement

within a single handheld unit.

This makes the 718 especially useful for service work on process instrumentation.

Pressure Switch Testing

The Fluke Calibration 718 incorporates a dedicated pressure switch test function.

This allows the switching behavior of pressure switches to be checked more conveniently than with separate pressure and continuity measurement equipment.

Fluke identifies the integrated switch test as one of the key functions of the 718 family. Fluke

This function is useful for determining the pressure at which a switch changes state during increasing or decreasing pressure.

Error Percentage Calculation

The Fluke Calibration 718 includes an error percentage calculation function.

This allows technicians to make faster pass/fail decisions when testing pressure transmitters.

Instead of manually calculating the deviation between the expected and measured transmitter output, the calibrator can provide the result directly.

Fluke specifically promotes this feature for quick field evaluation of calibration results. Fluke

Min, Max and Hold Functions

The 718 provides practical measurement functions including:

Min

Max

Hold

These functions allow changing pressure or electrical values to be captured during testing.

For example, the Max function can be used to record a pressure peak, while Hold can retain a displayed value for documentation or comparison.

Fluke also includes a damping function for applications where pressure fluctuations cause an unstable display. Fluke

Zero Function

The Zero function allows the pressure measurement to be zeroed before a measurement or calibration sequence.

This is an important function in pressure calibration because even a small zero offset can influence measurement results, especially at lower pressure values.

The Fluke 718 provides the Zero function together with Min, Max, Hold and damping functions. Fluke

Pressure Units

The internal pressure function supports several engineering units, including:

• psi
• bar
• mbar
• kPa
• inH₂O
• cmH₂O
• inHg
• mmHg
• kg/cm²

This allows the measurement value to be displayed directly in the unit used by the process or device under test. Fluke

Direct unit selection reduces conversion errors and simplifies international calibration work.

Intended Pressure Medium

Fluke specifies the internal pressure system for use with:

dry air and non-corrosive gases. Fluke

This is an important distinction from some pressure instruments that can be used directly with liquids.

For applications involving liquids or aggressive media, a compatible external pressure module or suitable separation method should be selected according to the relevant specifications.

Compact Handheld Design

The Fluke Calibration 718 is designed as a portable field instrument.

Dimensions are approximately:

216 × 94 × 66 mm.

Weight is approximately:

992 g. Fluke

The compact housing allows the complete calibration system to be transported easily between measurement points.

The protective holster also provides additional mechanical protection during everyday service work.

Battery Operation

The Fluke Calibration 718 is powered by two 9 V alkaline batteries.

Typical battery life is specified as approximately:

4 to 20 hours

depending on the functions being used. Fluke

The wide battery-life range reflects the additional energy required when functions such as loop power are active.

Battery operation allows the calibrator to be used independently of mains power during field calibration.

Environmental Specifications

The specified operating temperature range is:

-10 °C to 55 °C.

Storage temperature is specified as:

-40 °C to 60 °C.
