Fluke 789 Multi Function Calibrator, 1A, 1000V, 50 x 100 x 203mm

Fluke 789 Current Loop Calibrator

Fluke 789 has a 24 V loop supply and thus decreases the need to provide external auxiliary power to the transmitter when calibrating on-site. And thanks to its built-in switchable 250 Ω resistor, there is also no need for you to bring along separate resistors for calibrating Hart® instruments.
