Fluke 773 Milliamp Process Clamp Meter
Overview
The Fluke 773 milliamp process clamp meter saves technicians time and money by measuring 4-20 mA signals up to five times faster than a traditional multimeter, and without breaking the loop. This means process plant technicians can troubleshoot a live transmitter, valve, or PLC without powering down the system or risking a missed process event during a loop interruption.
With fast quotation turnaround and technical support, Seven Star LLC proudly supplies the Fluke 773 to instrumentation and maintenance teams throughout the Sultanate of Oman and the wider GCC. Every unit is supplied with manufacturer documentation and the technical support that process plant troubleshooting demands.
Measurement Principle
The Fluke 773 uses a non-contact clamp jaw to measure current flowing through a conductor by sensing the magnetic field it generates, allowing technicians to read a 4-20 mA loop signal without opening the circuit or inserting the meter in series. This non-invasive approach eliminates the risk of dropped connections, blown fuses, or process interruptions that come with breaking a live loop to insert a traditional meter.
Beyond passive measurement, the 773 can source and simulate 4-20 mA signals and provide loop power, letting a single instrument both read and generate the process signal needed to test transmitters, valves, and controllers end to end. It also sources and measures DC voltage, extending its usefulness to voltage-based I/O signals such as 1-5 V or 0-10 V control loops commonly found in process instrumentation.
Engineering Design of the Fluke 773
The Fluke 773 clamp jaw accommodates conductors up to 0.177 in (4.5 mm) in diameter and measures up to 99.0 mA non-contact, including 10-50 mA signals used in older control systems, with best-in-class accuracy of 0.2% and 0.01 mA resolution and sensitivity. The clamp section detaches from the main body and connects via an extension cable, allowing technicians to take measurements as a remote jaw in tight or hard-to-reach enclosures where the full meter body would not fit.
A dual backlit display shows mA measurement and percent of 4-20 mA span simultaneously, and an integrated measurement spotlight illuminates hard-to-see wires in dark enclosures. The Hold function captures readings on-screen for verification and recording, while automatic power-off conserves the four AA batteries that power the unit for extended field use. The 773 carries an IP40 rating and operates from -10°C to 50°C, backed by a three-year warranty on electronics.
Key Features
The Fluke 773 combines non-contact convenience with full source, simulate, and measure functionality for process loop work:
- Measures 4-20 mA signals without breaking the loop, up to five times faster than a traditional multimeter.
- Sources and simulates 4-20 mA signals with loop power for end-to-end transmitter and controller testing.
- Best-in-class accuracy of 0.2% with 0.01 mA resolution and sensitivity.
- Sources and measures DC voltage up to 30 V for 1-5 V and 0-10 V I/O signal troubleshooting.
- Detachable clamp section with extension cable enables measurement in tight, hard-to-access spaces.
- Integrated measurement spotlight illuminates wires in dark enclosures.
- Dual backlit display shows mA measurement and percent of 4-20 mA span simultaneously.
- Compact, portable design with magnetic hanging strap and soft carrying case for field mobility.
Industrial Applications
The Fluke 773 is a standard tool for troubleshooting transmitters, control valves, and programmable logic controllers throughout process plants, refineries, and water treatment facilities. In Oman’s oil, gas, and petrochemical sector, the 773’s non-contact loop measurement lets instrumentation technicians diagnose signal faults on live 4-20 mA loops without the downtime and safety exposure of breaking the circuit.
With engineering support in Muscat, Seven Star LLC supplies the Fluke 773 to instrumentation and maintenance teams across Muscat and the Sohar and Salalah economic zones. Its combination of source, simulate, and non-contact measurement makes it particularly valuable for commissioning and troubleshooting DCS and PLC-integrated process instrumentation throughout the GCC’s process industries.

Why Choose Seven Star LLC for Fluke Process Test Tools
A process clamp meter earns its place in a technician’s kit only if it is genuinely calibrated and traceable — an uncertified unit can pass a quick functional check while quietly drifting outside the accuracy your loop troubleshooting actually depends on. Seven Star LLC supplies the Fluke 773 with full manufacturer traceability and calibration documentation, backed by our trusted Fluke suppliership across Oman and the wider GCC. We also support instrumentation teams standardizing their test-tool fleet across multiple sites in Muscat, Sohar, and Salalah by coordinating batch procurement and consistent calibration renewal scheduling, so every technician on a maintenance team is working from the same verified toolset rather than a mix of aging or unverified meters.

Where Fluke instruments are used
Fluke process calibrators are used for loop checks, transmitter calibration and valve tests in oil and gas, power and water plants. Clamp meters and insulation testers serve electrical maintenance on motors, switchgear and cables. The bench calibrators and reference multimeters are the working standards of electrical calibration laboratories in the GCC, where they calibrate multimeters, clamp meters, process tools and power analyzers.Ordering Fluke instruments: what we need
Send the exact model with its suffix, since versions differ. A Fluke 721, for example, is defined by its two pressure ranges, and a 729 by its maximum pressure. For bench calibrators, list the options you need, such as oscilloscope calibration or power quality options, the line voltage, and the type of calibration certificate you require from the manufacturer. For Fluke multimeters and clamp meters, add the kit contents wanted, such as probes, leads or cases.Browse Fluke products by category: Portable Test & Measurement.
