Fluke 709 Calibrators

The Fluke 709 calibrators are 20mA loop devices that can both source and measure current for mA loop systems (0 to 20mA and 4 to 20mA). Featuring best-in-class accuracy at 0.01% reading, a resolution of 1μA on mA ranges and 1mV on voltages ranges these are highly accurate and sensitive devices. They are also designed for the busy technician in the field with compact, rugged design and an intuitive user interface for fast setup. In addition to the functions of the 709 (55-7019) the 709H calibrator (55-7020) can communicate with HART devices and log the data for transfer to a PC in either .CSV or .TXT format. Loop measurements and HART data can be logged from an individual transmitter for troubleshooting and loop tuning at selectable capture intervals of 1 to 60 seconds and a capacity of 9800 records or 99 individual sessions. Each data sample contains the 709H mA measurement, all four process variables and the standard status conditions. Both calibrators a re supplied with a NIST traceable calibration certificate with data, batteries, soft case and manual. The 709 is also supplied with AC175 alligator clips and TL75 test leads. The 709H is supplied with an extended tooth alligator clip set, stackable lead set, TP220 test probes, AC280 SureGrip™ hook clips and a HART cable.
