The Fluke 709 Series Precision Loop Calibrator is a high-quality device is used to install, calibrate, and troubleshoot field transmitters, valves, and other control system parts found in process plants. It can source and measure 0-24 milliamp signals. Also, it can create a 24-volt dc loop power and a 30-volt dc voltage measurement.
Featuring an accuracy reading of 0.01 percent, the Fluke 709 offers one microampere (μA) on milliamp ranges and one millivolt (mV) on voltage ranges. It has a variable step and ramp time and an adjustable span selection. Plus, the 709 series comes with a built-in HART 250-ohm loop resistor.
The 709 loop calibrator offers a small, compact rugged design that is ideal to use in harsh environments. It uses six AAA alkaline batteries that has a battery life up to 40 hours with typical use. In addition, this Fluke calibrator offers a graphic LCD display with backlight that produces readable results.
