Characteristics and functional analysis of Fluke 709HMA loop calibration instrument

I. Fluke709h Precision loop checkor product introduction: Fluke709HMA loop checkor can save both measurement time and generate high quality results. 709H with HART communication features and supports a set of HART general instructions and ordinary application instructions. This is a lot of 709h. It is both an economical, compact loop calibrator, and a powerful HART communication tool. Second, Fluke709H Precision loop checkor product Features: Fluke709h Calibrator Design There is a user-friendly interface and a Quick-Set rotary encoder knob. The tool reduces voltage, current measurement or output time and circuit power delivery time. Protective leather cases are particularly suitable for technicians. The large backlight display is easy to read, even in the dark, narrow work area. 709H Calibrator features: 0.01% Reading accuracy design Small and durable, depending on the 6-section standard AAA battery power supply intuitive user interface, Quick-set knob can quickly set, easy to use built-in HART communication 250Ω optional resistor 24V DC loop Power supply, with MA measurement mode (-25% ~ 125%) current range resolution is 1μA, the voltage quantity resolution is 1mV all measurements all measured with simple dual-line connection automatic shutdown to extend battery life (the longest adjustable time 30 minutes) Variable stepper and ramp time (seconds) Advanced span selection (0 ~ 20mA or 4 ~ 20mA) tube test (MA value defined by the% key simulation) HART Specific performance includes: fast transmission calibration data. 709H / Track Software / Cables Record parameters of all HART transmitters on your device in (.csv) or (.txt) format. The data can be recorded on a particular transmitter to facilitate troubleshooting. The data recording tool has 1 ~ 60 seconds of optional acquisition intervals, which can record 9800 records or 99 separate sessions. Each data sample contains 709h measurement, all four process variables and standard state conditions. In communication mode, the user can read basic device information, perform diagnostic tests and fine-tune most HART transmitters calibration. In the past, this operation can only be done with a dedicated communication, a high-end multi-function calibrator or a laptop with HART modem. Fluke709h allows almost any technician to repair and support HART devices. Editor in charge: GT, read full text
