Features and Benefits of the Fluke 707

The Fluke 707 combines essential loop calibration functions with intuitive operation and a portable design. It is optimized for technicians working with standard industrial 4 to 20 mA signals.

The Quick Click rotary control enables fast adjustment of output values with one hand. Current values can be changed precisely while the technician remains focused on the device or process being tested.

Important features of the Fluke 707 include:

High accuracy

The Fluke 707 provides an accuracy of 0.015% for mA measurement and sourcing, supporting reliable calibration of industrial current loops.

Measure, source and simulate mA

The calibrator supports the essential operating modes required for testing current loop instrumentation. Technicians can measure an existing current signal, generate a defined current or simulate a transmitter output.

Quick Click rotary control

The intuitive rotary control simplifies current adjustment. Output values can be changed quickly and precisely during calibration procedures.

Integrated loop power

The Fluke 707 provides 24 V loop power for testing compatible transmitters. This reduces the need for an additional external power supply during many calibration tasks.

Automatic stepping and ramping

Automatic output functions make it easier to test the response of transmitters, indicators and control system inputs across the operating range.

Compact handheld design

The portable construction makes the Fluke 707 ideal for maintenance and calibration work directly in industrial plants.

Precise 4 to 20 mA Loop Calibration

Industrial process instrumentation commonly uses a 4 to 20 mA current signal for transmitting measurement values between sensors, transmitters and control systems.

The Fluke 707 is specifically designed for working with these signals.

Technicians can use the instrument to verify whether a transmitter generates the expected current output for a particular process value. The Fluke 707 can also generate current signals to test indicators, controllers, PLC inputs and other connected instrumentation.

With a resolution of 1 µA, small changes in current can be displayed and adjusted precisely.

This makes the Fluke 707 suitable for calibration and troubleshooting applications where reliable current signal generation and measurement are required.

Measure, Source and Simulate Current

Current Measurement

The Fluke 707 Loop Calibrator measures DC current signals up to 24 mA.

This covers the standard 4 to 20 mA range used throughout industrial process measurement and automation.

Current measurement can be used to check the output signal of pressure, temperature, flow, level and other process transmitters.

Current Sourcing

In source mode, the Fluke 707 generates a defined current signal.

This allows technicians to simulate a transmitter output and verify how a connected control system responds to different process values.

The output can be adjusted manually using the rotary control or automatically using the step and ramp functions.

Current Simulation

Simulation mode enables the Fluke 707 to act like a two wire transmitter within an externally powered current loop.

This function is particularly useful when testing industrial control systems and analog input channels.

Integrated 24 V Loop Power

An important feature of the Fluke 707 is its integrated 24 V loop power supply.

Many industrial two wire transmitters require an external supply voltage to generate their 4 to 20 mA output signal.

The Fluke 707 can provide the required loop power while simultaneously measuring the transmitter output.

This functionality reduces the amount of equipment technicians need to carry and simplifies calibration procedures directly at the installation site.

For technicians performing routine maintenance on process transmitters, this combination of loop power and current measurement provides a practical and efficient workflow.

Automatic Step and Ramp Functions

The Fluke 707 includes automatic stepping and ramping functions that simplify repetitive calibration procedures.

The instrument provides 25% stepping, allowing the current output to be changed through predefined points across the selected range.

For a standard 4 to 20 mA signal, these points correspond to important positions within the transmitter range.

Automatic ramping continuously changes the output signal, making it easier to observe the response of indicators, controllers and other process equipment.

These functions are particularly useful for:

Testing transmitter linearity

Checking analog control system inputs

Verifying indicators and displays

Testing alarm points

Checking process control equipment

Troubleshooting current loops

Voltage Measurement for Process Applications

In addition to current loop functions, the Fluke 707 can measure DC voltage up to 28 V.

Voltage measurement is useful when troubleshooting process instrumentation and checking power supplies within industrial current loops.

Technicians can therefore use a single compact instrument for both current calibration and basic voltage verification.

Technical Specifications of the Fluke 707

Detailed specifications and accuracy conditions should always be considered according to the manufacturer’s technical documentation.

Ideal for Industrial Calibration Applications

The Fluke 707 is particularly suitable for technicians and engineers working with industrial process instrumentation.

Process Transmitter Calibration

The instrument can measure transmitter output signals and provide loop power for compatible two wire transmitters.

This makes it suitable for testing pressure, temperature, flow and level transmitters.

Control System Testing

By generating defined current signals, technicians can verify analog inputs on PLCs, process controllers and data acquisition systems.

Industrial Maintenance

The compact design makes the Fluke 707 suitable for routine maintenance and troubleshooting directly in production environments.

Field Calibration

Battery operation and portable construction enable calibration procedures to be performed directly at the measurement point.

Quality Assurance

The Fluke 707 can also be used for functional testing and verification of process instruments during production and quality assurance procedures.
