Fluke 789 ProcessMeter
Fluke corporation is the world leader in the manufacture, distribution and service of electronic test tools and software. Since its founding in 1948, fluke has helped define and grow a unique technology market, providing testing and troubleshooting capabilities that have grown to mission critical status in manufacturing and service industries. As electrical systems grow more and more complex, spikes, transients, surges, and sudden over voltage events become more common. These can trigger a sequence of events that may lead to serious injury. This is why test equipment must be designed to protect people who work in this high-Voltage high-current environment. Now process technicians can do a lot more while carrying a lot less. The fluke 789 has a 24-Volt loop supply that reduces the need to take a separate power supply when doing offline transmitter testing. And with its built-in, selectable 250-ohm hart resistor, it also eliminates the need to carry a separate resistor with you. The fluke 789 processmeter simulates dc loop current with .05-Percent accuracy and 1-microamp resolution. The 789 has 25-Percent manual step plus auto step and auto ramp on ma output, 1200 ohm drive capability on ma source, and zero and 100 percent buttons to toggle between four and 20 ma sourcing for a quick span check. The 789 features a large dual display with enhanced backlight with 2 brightness settings, and weighs just over one pound (600 grams). The external accessible battery is easy for battery changes. The processmeter runs about 140 hours typical (measurement), 10 hours typical (sourcing 20 ma) on four aa 1.5-Volt alkaline batteries (included). Also included are the following: a quick reference guide, a manual, a set of ac70a alligator clips, and a tl75 safety-designed test lead set. The 789 meets 1000 volt en61010-1 cat iii standards and 600 volt en61010-1 cat iv standards, and passed a one meter drop test. The fluke 789 processmeter is sold one item per package.
