Product Details Supplier Info More products

Fluke has launched the 772 and 773 milliamp clamp meters, designed to help technicians test critical automation and control circuits without breaking the circuit or interrupting operations.

The tools are aimed at instrumentation technicians, contractors and process and control installers who carry out milliamp loop troubleshooting on process control circuits, instruments and automotive systems.

The 771, 772 and 773 milliamp clamp meters are engineered to accurately measure the minute amounts of current (4-20mA signals) that flow through control system circuits, without having to shut down the system, break the circuit and insert a test instrument.

Instead, sensitive current clamps placed around the wire detect and measure the current flowing through.

In addition, the Fluke 772 and 773 can be used to simultaneously source, simulate and measure milliamp signals in a broken circuit, negating the need for additional tools.

The Fluke 773 will also source and measure DC voltages for troubleshooting voltage input and output devices; will power a transmitter for independent checking of its mA output signal; and will provide a scaled output signal to provide data logging by a Fluke 280 series digital multimeter, for example.

Without breaking the loop, the backlit display will give simultaneous milliamp and percentage span readings, with milliamp resolution to 0.01mA.

The Fluke 771/772/773 feature a detachable clamp that can be used docked, or detached via its extension cable to facilitate measurement in tight spaces, and a hold function to capture and display changing measurements for convenient viewing.

A built-in flashlight illuminates wires in dark enclosures, and a battery-saving feature cuts in automatically after prolonged inactivity.

Users can also measure 10-50mA signals in older control systems using a 99.9mA range.

The Fluke 771/772/773 milliamp clamp meters are supplied with a soft carrying case.

Fluke Calibration

Fluke Corporation was founded in 1948, specialising in electrical test and measurement products. Early in its history, Fluke recognised that the very best electrical metrology would be needed to support its products and undertook to develop this capability. From this activity, the calibration business was born. Over the years, many breakthrough calibration products were introduced, establishing Fluke as a leader in electrical metrology.

In 2000, Fluke acquired Wavetek Precision Measurement. In 2001, Fluke’s calibration business expanded into the temperature field with the acquisition of Hart Scientific and then into pressure and gas flow with the acquisition of DH Instruments (2007), followed by Ruska and Pressurements (2010).

The unified business’s unmatched breadth and depth in metrology puts Fluke Calibration in a unique position to deliver today’s and tomorrow’s calibrations solutions to customers who demand the very best, supported by an organisation they can count on for the long term.
