Fluke (UK) product story
Edited by the Engineeringtalk editorial team
May 2, 2007
The Fluke 771 clamp meter delivers 0.2% accuracy with resolution and sensitivity to 0.01mA for testing and troubleshooting PLC and control system analogue I/Os.
Fluke has introduced the Fluke 771 milliamp process clamp meter, which measures 4-20mA output signals from transmitters in process and industrial control system applications without breaking the current loop.
Offering increased productivity for process and plant maintenance technicians and commercial electricians, the Fluke 771 delivers 0.2% accuracy with resolution and sensitivity to 0.01mA for testing and troubleshooting PLC and control system analogue I/Os.
It is designed for use in environments where it is impractical to shut down processes, or put systems into "safe" mode, in order to break the loop and place a meter in series with the circuit to take measurements.
It features a detachable clamp that can be used docked, or detached via its extension cable, to facilitate measurement in tight spaces, as well as a measurement spotlight that illuminates wires in dark enclosures, and automatic battery saving features.
The Fluke 771 has a dual backlit display that shows both mA measurement and percentage of 4-20mA span, and a hold function to capture and display changing measurements for convenient viewing.
Users can also measure 10-50mA signals in older control systems using the 99.9mA range.
The Fluke 771 is supplied with a soft carrying case and can be purchased from Fluke authorised distributors.
