รายละเอียดสินค้า Fluke 709H
Precision Current Loop Calibrator with HART Calibration
-
Best-in-class accuracy at 0.01 % reading
-
Compact rugged design
-
Intuitive user interface with quick-set knob for fast setup, easy use
-
24 V dc loop power with mA measure mode (-25 % to 125 %)
-
Resolution of 1 µA on mA ranges and 1 mV on voltages ranges
-
Built in selectable 250 Ω resistor for HART communications
-
Simple two wire connection for all measurements

-
Fast transfer of calibration data. The 709H/Track software/cable documents the parameters of all the HART transmitters in your plant, in either (.csv) or (.txt) format
-
Data logging or recording data on a particular transmitter for troubleshooting. The data log tool offers selectable capture interval from 1 to 60 seconds and a logging capacity of 9800 records or 99 individual sessions. Each data sample contains the 709H measurement, all four process variables, and the standard status conditions.
