JOperation this meter to diagnose electronic problems I can have at home. Jai tested some options such as thermometer function (for my PC and coolant) and frequency measurements for lighting problems. It works very well and that he japprécie lights up to where I have to plug it in and it beeps when jOperation bad connections. The part on the back that allows it upright BE is very convenient to have a free hand. There is a feature to the sound (to measure the number of decibels), the intensity of light, temperature, and the rate of moisture that are significant functions. The cables included are solid. The quality is good for the price.
