Description
Adjustable Analog 4-20mA Current Source Signal Generator Testing:
Main Features
• Have backside cover for dust-proof.
• Potentiometer knob calibration, output is adjustable through the knob, fast response.
• Highly sensitive adjustment by multi-turn potentiometer, adjusting step: 0.1mA.
• Used as 4-20mA current source signal, 4-20mA generator, vale adjustment, meters testing, etc.
• Clear LED RED digit display can be used in industrial field with different lighting conditions.
• Standard panel-mounted size, easy to do further integration.
• Output precision can be calibrated by adjusting the multi-turn potentiometer inside the signal generator.

4-20mA Source Signal Generator Referential Applications
*Note:
BRT 4-20mA-GEL: Multi-turn Rotation: the adjusting knob rotation angle is 5 x360 degree from 4mA to 20mA, the output signal adjusting step is smaller.
