Fluke 772

Fluke 772 is a portable, battery-operated device designed for troubleshooting sensors, valves, PLCs, and DCS inputs/outputs. Unlike conventional clamp meters, this device features a remote clamp connected to the main unit via an extension cable.

Features

• Generates 4 - 20 mA signals for testing control system inputs/outputs and current-to-pressure converters;
• Simulates 4 - 20 mA current signals for testing control system inputs/outputs;
• Measures 4 - 20 mA signals within the circuit;
• Provides 24V loop power for transmitters;
• Automatic linear and step changes of 4 - 20 mA signal for remote testing;
• Measures DC voltage for checking 24V power supply or voltage input/output signals;
• Generates DC voltage for testing devices that accept voltage signals;
• Scalable milliamp output allows a digital multimeter (289) to log 4 - 20 mA signals without breaking the circuit;
• Milliamp input/output: simultaneous milliamp signal generation and measurement with clamps.
