  • it is 6000 counts and very good and accurate, i am very happy about it.
    but PLEASE we must have an ENGLISH manual.

  • I need link to user's manual in English or link to Chinese manual so I can have it translated online.
    Questions I need answered:
    What is NCV (non contact voltage detector). How does it work/sensor used.
    What are specifications for accuracy.
    The diode check/ connection beep allows selection for beep, diode check, both. what does both do?
    What does hold button do?

    What I did was with my phone I used Google Translate and took Pictures with the manual that came with the meter. Hope this helps.

    David. the NCV is like your AC mains stick. You can hold the meter up to a mains circuit (power point or cable) and see if it is live or not. I have this on a different meter and I too was curious what it was. Mind you I have only used it to try out the function (not sure if it will inductively t\measure the voltage as well, might try mine out when I get back to my office)l. Much easier carrying the volt stick on my pocket. HTH.

  • An outstanding Multimeter at an outstanding price. Very professional look and feel and a magnitude of options (Farad, Hertz, hFE and the other usual stuff), backlight. Good clip to place it upright, Auto-off after a while preserves the battery. Everything my old one did not have. Cons: the beeps: maybe there is a way to switch it off... or remove the beeper or install a switch ;-) and that brings us to the manual: Chinese only but if you ever used a Multimeter before you will not become distracted by looking the manual as everything is where it should be. I'll see to get another one with my next order... it would make a good X-Mas present for other Nerdies too... Lovin' it.
