Great meter.
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

Great for troubleshooting BAS systems
Works great to verify BAS devices can read 4-20 mA or 0-10 volt inputs. I use it for troubleshooting all the time.

Not very accurate on the low end of 4-20 mA
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.

Well worth the price
Easy to use and works like a charm.
