Thats a nice common sense , objective review ,giving only the information nescessary . Like you say it's very easy these days to make an accurate meter , something like this ideal if your only using it on low voltage electronics or as an often needed second meter to your expensive high cat rated one . |

It was hard to resist buying at that price... The meter's measurement functions and specification are good on paper. I put it through the paces and indeed, it seems to be as advertised. It's definitely built down to a specific price however. It's interesting how you can buy a multimeter anywhere from $10 to $100 in $10 increments these days, with each increment in $'s buying just a bit more quality. Good measurement accuracy, however, seems to be common even in these very low cost meters. --- End quote --- Sir , can you share that website link of vichy please |

Hi Amarbir, Their english web site is: http://vicimeter.com/en/index.asp To the person who asked if the autoranging of the meter can be speed up: The main controller chip appears to be a "FS9922-DMM4" from Fortune Semiconductor. If you google it, a pdf data sheet is readily available. The only oscillator control appears to be crystal. In theory that that could be replaced with a higher value, however, this would be overclocking outside of the data sheet so there is no guarantee it work(and the frequency counter, for sure, would now be inaccurate). |

Thanks electronupdate , i'll look at it a bit later but i gather it'll have a crystal there that is already at maximum ratings(speed)i hope , did you notice the frequency in the review? but don't fret if you did not as i'll look in mine at a later date , yet it will be interesting to have a look anyway of the data sheet of the ic . cheers.... edited>added> just took a quick look and 4mhz in data-sheet , and wow , alot of features in that small ic imo ... |
