Current Loop Calibrator, Fluke 707Ex - Fluke
Current loop calibrator The Fluke 707Ex Calibrator is designed to quickly test the current loop. It is equipped with a new interface Quick Click, allowing you to set the exact value of the current (mA). Turning the knob one "click" changes the current output by 0.001mA. Rotating the depressed knob will change the values by 0.100mA with each "click". The large digital display will show the values you have set. Fluke 707Ex Calibrator Features: Large display and user-friendly one-handed interface; Simultaneous display of mA and % for quick and easy interpretation of readings; 0.015% is the best mA...Current loop calibrator

The large digital display will show the values you have set.Fluke 707Ex Calibrator Features:
- Large display and user-friendly one-handed interface;
- Simultaneous display of mA and % for quick and easy interpretation of readings;
- 0.015% is the best mA accuracy among calibrators in this price range;
- 1µA resolution for mA measurement and simulation;
- Function of automatic checking of linearity of transducers with a step of 25%, started by pressing a button;
- "Span Check" function to quickly determine the level of the calibration signal from 0% to 100%;
- Choice between slow and fast sawtooth (ramp), as well as step-by-step (in 25% steps) increase in the current strength at the output of the calibrator for the functional test of the current loop;
- Internal 24V loop power, so you can power up and read transducer parameters at the same time without using a DMM; - DC voltage measurement up to 28 V;
- One easy-to-replace 9V battery;
- Factory settings allow operation with 0 - 20 mA or 4 - 20 mA circuits.
- Progressive current output setting with 1 µA and 100 µA resolution.
- For use in explosive areas
- ATEX certification ( II 2 G Eex ia IIC T4)
The Fluke 707Ex is compatible with HART equipment. The HARTTM function allows the instrument to be connected in series to the current loop, provided that the load resistance between the device under test and the 24V power supply must be at least 250 ohms.
