More About this Item
These calibrators are built around a user-friendly interface with a Quick-Set rotary encoder knob. This tool reduces the time it takes to measure, or source, voltage or current and power up a loop. Compact, rugged design with protective holster easily fits into a technician’s hand. A large backlit display is easy to read even in dark, cramped worked areas.
Model 709H Additional Features This unit adds HART communication and offers 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 measurement, four process variables, and standard status conditions. This tool also offers fast transfer of calibration data. Use the optional Track software to document the parameters of all the HART transmitters in your plant, in either (.csv) or (.txt) format.
Additional What's included: Model 709H also includes extended tooth alligator clip set, 75X-8014 stackable lead set, TP220 test probes, AC280 SureGrip hook clips, and HART cable.
