### ⭐⭐⭐⭐⭐ Compact and good quality product
*by S***H on 13 April 2024*

Very good product with built in battery which makes it very portable. I can move it to where I need to generate a 4-20mA signal easily. And also used for give the 0-10 V

### ⭐⭐⭐⭐⭐ Review
*by T***S on 9 October 2025*

SImple to use. Battery was charged when I received so I was able to play with it right away. Also has capability to run off 24VDC power or USB adapter (comes w/cord but you'll need the USB power supply/phone charger) Good value; I'm not looking for a calibration quality device so it fit my needs. I will be using it as a 4-20mA source. It outputs at 24VDC in the mA generator mode. It was accurate enough for what I will be using it, mainly troubleshooting or modeling. I don't need to be highly precise. I noticed the signal bounced somewhat, but it was in the magnitude of .01's. This difference just as well could be from the precision of the controller/PLC that I was connected to. Comes with a USB power cord and little tweaker screwdriver. Nice to have when you are working in the field.
