4-20ma Signal Generator,Frequency Generator,Two-Wire High Accuracy 4-20mA Current Loop Signal Generator LCD Transducer Test Signal Current

I test and help develop PLC controls for water booster systems. When bench testing programs, I do not always have pressure on my transmitters or flow sensors to be able to test program functions. These are a SUPER easy to use tool for that purpose. They are loop powered, so they require no internal battery, and you turn the dial up and down to sweep from 4-20mA. To test sensor failure, you can just unplug them.Highly recommended for your toolkit!

This is as good a value as I've seen for this style 2-wire 4-20mA signal generator. Includes a full manual that isn't perfect, but it does a good enough job of describing the operating instructions.5 stars for value, would order again.

The media could not be loaded. Well made and functions as expected. Slightly off according to my budget multimeter but not enough to warrant a calibration for my typical projects. Useful piece of equipment to have around your electronics shop.Comes with a very good data sheet that explains all the functions and how to program it. It works out of the box though, so don't let that last comment scare you. If you're still hesitant, or just curious, there are very good instructional videos available that delve into the features of this exact frequency generator.
