ما أنصحكم فيه لان اغلب الي عليه شرح باليوتيوب ماهو مثله يختلف كثير ومعقد

This is an excellent gadget for the price. Wide ranges for ohms, volts and current (although I wouldn't recommend using this for anything more than household supply), also measure capacitance and temperature, which a lot of the cheaper ones don't do. Parameters that are easily tested (temperature, frequency, resistance) are completely accurate, so I assume everything else is. The case is a nice touch. Minor complaints: the beep whenever you change the switch is annoying and can't be turned off, and it would be nice to have the parameter you are measuring displayed more prominently. Also, the "ears" to put the probes in are a bit silly. Still, well worth it for the price.

Positives: Good measurement device that is small and easy to use. Negatives: The NCV function does not work very well for identifying cable routes through (thick) walls. The wrist strap is a bit difficult to use.

I bought this handy little meter from Best Meter.. 1st and foremost excellent customer service. I contacted the seller re: even though w/in spec the temperature reading was a bit high.. The seller provided calibration instructions such that it now reads on the money... In fact just recently I had ocassion to check the temperature reading @ well over 100 degF, this meter was spot on... Great service, quick response. Great price / value, What is this meter best for? very inexpensive for the features, these features make this my goto meter for take along field measurements. -small size, easy to "carry along” in tool bag or pouch. -side probe holders, very convenient for storage and allowing use of probe attached to meter so eyes are on contact point and meter. -magnet so you can affix it to a metal door (breaker box) etc. to free your hands for taking measurements - the display is large for a (small) meter this size => good for my "old eyes" -the display is 4 digits (6000 cts) , good accuracy. -auto ranging, -audible continuity, easy to tell w/o looking @ the meter, actually very quick response compared to other meters near this price point. - automatic backlight, based on available lighting.. - the wrist strap may be useful to some, I'll likely never use it. -battery and fuses in same easy to access compartment.. so you don't have to do major disassembly to replace either. Battery test (1.5v & 9V) puts a load on batteries so you can tell the remaining life. shortcoming(s): - the included leads in this "budget" meter are adequate, I recommend if you have more than infrequent use invest a few $$ in a good set of test leads. - The current "marketing hype" with several of the "newer" DMM's is NCV, Non-Contact Voltage check.. As most reviewers point out, this feature is inconsistent.. I would never trust this. Manufactures will either improve this feature or it will go away. -glass fuses, vice sand filled, at a budget price this is what one would expect, some users will tell you the sand filled fuses are "better protection" true ,if the meter is subjected to conditions well beyond its design, but in all of my 60 years I have never blown afuse on a meter.. Would I recommend this meter, YES for the $$ it is a great value

Everything works great, including auto range and thermocouple. Probes are excellent, protective covers, very sharp,and bronze flashed. Throw the battery in the bin! When tested it measured 9V but even a mA of current caused the voltage to drop rapidly. This explained the meters behaviour - switching on but resetting every second, making to look like a factory dud.
