Simple, Small and works great!
This 4-20ma generator is live. You do not have to press the button to save the output. As you scroll up - so does the output. Is small form is great. I like that fact that this one is Loop Power! I will be buying more to add to my PLC Stand.

Works as expected. Simple as could be.
Works great for troubleshooting or building out loop receivers.

Buy a more expensive tester.
Broken upon arrival. No matter the direction of voltage input screen will not light up, when in line with my current input voltage drops to 3.2v. I also tested with my other sensors to be sure the card was wired correctly, this device is none functional at best.

These are VERY lightly built, and intended for a panel mount.... But they work great!
Needed a quick trouble shooting 4-20MA generator. These were inexpensive and shipped quickly. Powered on and started using right out of the box. The range is ONLY 4-20 MA, (not below 4MA or above 20MA) but the resolution is very accurate and worked great. Definitely was a cost-effective solution for me.

Performance
Works great for my project simulation. Only problem is it doesn’t keep previous value when power turns on back.

Great unit.
I use this for generating an analog signal for speed signals while testing in QC. It’s a loop-powered generator that is cost-effective, simple and does exactly what I need.

Works well
Purchased this signal generator four months ago, to simulate an industrial sensor input on a monitoring device prototype. It has been running 24/7 since then and still going strong.

Problem with display
There is a shadow area and the display is not fully lit. The second one in the batch seems to work as intended. I will require a replacement- Waiting on seller to contact me back-
