Fluke 773 CAL Milliamp Process Clamp Meter

Overview

The Fluke 773 CAL Milliamp Process Clamp Meter is a precision troubleshooting tool for instrumentation and control professionals who require verified accuracy and documented calibration. Manufactured by Fluke, this CAL version includes NIST traceable calibration with data, making it suitable for regulated environments and quality-critical applications.

The Fluke 773 measures 4–20 mA signals up to five times faster than traditional methods by allowing non-contact measurements without breaking the loop. This enables technicians to diagnose live transmitters, valves, and PLC I/O without shutting down systems or disrupting processes.

Why You Should Buy It

The Fluke 773 CAL is ideal for professionals who need documented accuracy, regulatory confidence, and maximum efficiency. NIST traceable calibration ensures compliance with quality systems, while non-contact loop measurement minimizes downtime. Its ability to measure, source, and simulate both mA and voltage signals makes it a powerful all-in-one tool for maintaining modern process and automation systems.

FAQ – Fluke 773 CAL

What is the difference between the Fluke 773 and 773 CAL?
The 773 CAL includes NIST traceable calibration with data, suitable for regulated and quality-controlled environments.

Can it measure 4–20 mA without breaking the loop?
Yes. The clamp allows non-contact measurement of live 4–20 mA signals.

Can the Fluke 773 CAL source and simulate signals?
Yes. It can source and simulate 0–24 mA and output DC voltage for device testing.

Is it suitable for PLC and transmitter troubleshooting?
Yes. It is designed specifically for PLC analog I/O, transmitters, valves, and mA isolators.

Does it support data logging?
No. The Fluke 773 CAL focuses on real-time measurement and calibration rather than logging.
