Awesome little box. Does everything advertised, shipped fast, fair price. The rechargeable battery feature is nice, the display is easy to read, buttons well marked and simple to use.

The directions suck! Once you know where all of the ports are, throw the instructions away. The Chinese manufacturer used Google to translate the booklet, so you get "You thank me very much please when you buy this" The multi-range features are glossed over completely and how you get to some of the functions is a complete mystery.

This little device is worth it's weight in gold. This has saved hours of debug time and thousands of dollars in verifying what device is actually causing the issues with measurements. It hold it's charge for a very long time when not in use. I have never had this device die while using. I just charge about every 3 months or so.This device is very accurate. The description is accurate in how accurate this device is. I use it all the time calibrating analog inputs on Allen Bradley controllers.

I had a job that require sourcing an RTD signal and it work great. The only complain I have is that this unit can only be use in Celsius mode and being in US we use Fahrenheit had to use my Cell Phone to do the conversion..~~ what is 60°C, let me pull my cell phone to convert 140°F ~ :O) little cumbersome when doing calibration testing but overall happy with unit.

So far I'm pretty impressed with it. I use it with my HART modem and laptop to calibrate valve positioners and run diagnostics. The battery lasts a long time and you can charge it while using it. Fits in my tool bag a lot better than my fluke. I added a magnet to the back so I can stick it to valves instead of using wire extensions.

I use this for troubleshooting loop powered instruments. It "works" in the sense that it carries out that function. My complaint is that the HMI is so simplistic I am never sure what it's actually doing so, I'm never confident in my results. I'm upgrading to a better device.

This thing works like a charm! I'm an HVAC technician. Use this to test VFD drives, ECM motors and actuators. Instructions kindve suck. Not sure how to tell when it's fully charged. But it's accurate as hell. Used it today on a Vari-Green motor. Replaced the motor but the speed controller wasn't in yet. Used this guy to test the 0-10VDC speed signal. Worked perfectly.

Nice little piece of equipment. It works well and does a lot for the money. I compared it to several meters I own and it appears to be accurate although I have not compared it to a calibrated standard. The o y downside is that it is a little small and the instructions could be a little better
