The Fluke 15B is a very, very basic multimeter. The BM257 is even better than the Fluke 17B. It's not just a list of obvious measurement features. The BM257 will warn you if the probe is in the "amps" socket and you turn the dial to measure volts. This feature will save your expensive fuses from silly mistakes. --- End quote --- Perfect thank you very much. Apart from all the other functions, the warning of the probe in the wrong socket is very important for me, the first days I will be very careful I would not want to burn the fuses immediately, all the functions I will learn a little at a time even if I have seen several tutorials in English but there are subtitles Thanks for everything. Greetings to you and everyone. |

Hi, a few months ago I bought the Brymen 257s, I noticed an anomalous thing, short-circuiting the leads should immediately go to 0, this does not happen, do you think the multimeter has some problem ? https://www.youtube.com/watch?v=wX4Cy5j68Ho&lc=UgyhIyhzV40Q3iIupUF4AaABAg.9Xv1WUGGoTU9Xx4TMxtg53 https://youtu.be/wX4Cy5j68Ho |

Your meter is fine. In the video you linked, the meter is in ACV function. BM257s is TrueRMS meter. It is normal behaviour for such a meter in ACV function. In DCV function, it should go to zero immediately. |

Also do be aware that for this DMM the AC volts function is only specified for between 5% and 100% of the range. Since this is a 6,000 count DMM, that is 0.3V for the 6V AC range, for example. So switch to the 600mV AC range instead or even the 60mV AC range if appropriate. |

Thank you so much for answering me, very kind @mqsaharan How do I switch from ACV function to DCV function ? I don't read ACV and DVC on the multimeter @JR Again I did not understand how to switch to the 600mVAC range or the 60mVAC range, do I need to disable the AUTO function and switch to manual mode ? -------------------------------------------------------------- EDIT : Ok I understand, I was confused by the acronyms I should go from alternating to direct voltage DCV (Direct Current Voltage) direct voltage ACV is the alternating voltage (Alternating Current Voltage, Alternating Current Voltammetry) Measurement of alternating and direct currents) ACA Alternating Current (Ampère) DCA Direct Current (Ampère) (Measurement of alternating and direct voltages) ACV Alternating Current (volts) DCV Direct Current (volts) Yes in direct voltage it goes to zero, but short-circuiting the test leads should also do so in alternating voltage ? |
