## Customer Reviews

### ⭐⭐⭐⭐⭐ Great little unit
*by R***O on March 15, 2022*

Exactly what I expected. I have tested directly upon delivery output signal values on a bench multimeter on their accuracy, and looks good.Next step will be testing the Hart and Modbus functionality. (Will update the review once completed)It would be helpful if the manual could improve and go a bit more in depth how to used this part of the unit. Hart/Modbus.The unit can be charged via USB (cable is included in the package)The unit is delivered with banana plugs and clips, I was surprised by its good quality.

### ⭐⭐⭐⭐⭐ Great meter.
*by A***N on February 21, 2019*

Haven't used all the functions, but so far it works as expected. Started to build one from panel parts, soon found that I had double the cost and half the capability. Very nice

### ⭐⭐ Not very accurate on the low end of 4-20 mA
*by D***Y on March 30, 2024*

Meter is extremely off on the low end of 4-20 mA. I have zero idea how it works with thermocouples, but somehow it works fine if you use copper/copper wire the whole way and was fairly accurate in all of the thermocouple types that I tried (K/S/B)Another drawback is being limited to Celsius from the temperature side. I’m sending mine back and going with a different option.The Memocal 2000 in the screenshots is pretty accurate and calibrated to ISO 17025 standards.
