Loop calibrator has innovative interface

27 March 2002 Test & Measurement

The Fluke 707 Loop Calibrator is the newest member of its family of portable process calibration tools. It features a new ergonomic design that combines the best of knob-based and button-based loop calibrators in one device, according to the company. It is designed to be compact and easy to hold so that technicians can operate the tool with just one hand. At 152 mm in length and weighing 340 grams, the Fluke 707 is a rugged calibration tool that can source, measure, and simulate loop current.

The Fluke 707 is claimed to be 2,5 times more accurate than any other loop calibrator in its class, with a 0,015% accuracy and 1 µA resolution in any current mode. A 24 V internal loop supply enables the user to power and read a transmitter at the same time using one instrument. It provides simultaneous milliampere and percentage of span readouts, making it ideal for process instrument technicians in the primary metals, refining, chemicals, pharmaceuticals, and power generation industries. Selectable slow ramp, fast ramp, and step functions provide the user with test signals needed for valve slewing and loop functional tests, allowing a single technician to troubleshoot the entire loop.

The Span Check function instantly selects zero and 100% of span outputs. A 25% button conducts quick linearity checks at 25% steps, and an innovative knob style allows fine and coarse adjust vernier with 1 µA and 100 µA resolution. The calibrator can measure loop power supply voltages up to 28 V d.c. Battery replacement is accomplished through a quick-change door, without compromising the calibration. It is backed by a three-year warranty and comes complete with test leads, test clips, and a protective C-10 holster that allows hanging from pipes, rails and joists.
