The Fluke 709H calibrator is 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. The protective holster easily fits into a technician’s hand and the large backlit display is easy to read, even in dark, cramped worked areas. The 709H offers : Best-in-class accuracy at 0.01% reading, Intuitive user interface with Quick-Set knob for fast setup, easy use, Built in selectable 250 Ω resistor for HART communication, 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 & Auto Shutdown to conserve battery life (adjustable up to 30 minutes).
Functions mA source, mA simulate, mA read, mA read/loop power, and volts read. Ranges mA (0 to 24mA) and Volts (0 to 30VDC) Resolution : 1 µA on mA ranges and 1 mV on voltage range Accuracy : 0.01% +/- 2 counts, all ranges (@23° +/- 5°C) Operating Temperature Range : -10 °C to 55 °C (14 °F to 131°F) Humidity Range : 10 to 95% non-condensing Stability : 20 ppm of F.S. /°C from -10°C to 18°C and 28°C to 55°C Display : 128 x 64 pixels, LCD Graphic w/backlight, .34 high digits Power : 6 AAA alkaline Battery Life : 40 hours typical Loop Compliance Voltage : 24VDC @ 20mA Over-Voltage Protection : 240 VAC Overload Current Protection : 28 mA DC EMC : EN61326 Annex A (Portable Instruments) Dimensions (L x W x D) : 15 cm x 9 cm x 3 cm (6 x 3.6 x 1.3) Weight : 0.3 kg (9.5 ounces) Included Accessories : NIST traceable calibration certificate with data, batteries, test leads, and manual
The CMC 356 is the universal solution for testing all generations and types of protection relays. Its powerful six current sources (three-phase mode: up to 64 A / 860 VA per channel) with a great dynamic range, make the unit capable of testing even high-burden electromechanical relays with very high power demands. The CMC 356 is the first choice for applications requiring the highest versatility, amplitude and power. Commissioning engineers will particularly appreciate its ability to perform wiring and plausibility checks of current transformers, by using primary injection of high currents from the test set.
