The only 2 answers you should pay any attention to because sooner or later they will be the only 2 things you will consider when you see/""need"" new instruments or equipment......YOU'LL SEE!! >:D >:D >:D |

Higher precision acquisition, or faster acquisition at lower precision. Remote SCPI control (including high speed acquisition) - in modern instruments using VXI-11 over ethernet. In many cases multiplexed inputs that lets you scan many measurement points from a single instrument. In modern instruments, a larger display for things like tabulated probe hold readings and statistics. 4W measurements. Stackable. |

Two things that haven't been mentioned: 1) Reading speed. Most handheld DMMs run at a few readings a second, the fastest bench DMMs can run at 100,000 4.5 digit readings a second. If you need to measure fast events more accurately than an oscilloscope can then you need this. It's also a question of throughput. It's no accident that a lot of these high speed DMMs end up in racks on the test equipment for electronics and semiconductor production lines. 2) Accurately triggered readings. Most higher end bench DMMs have a trigger input that you can use to get readings at well defined times related to what your DUT is doing. |

You can get 4.5 digit meters as hand held OR bench meters. I have 2 hand held 4.5 digit meters. I know you can get them as bench meters as well. As far as I know you can ONLY get 5.5 digit meters as bench meters. The same is true for 6.5, 7.5 and 8.5 meters. So my original statement was correct --- Quote ---You can only get 5.5 or more digit meters as bench meters. --- End quote --- --- End quote --- Your statement was a bit ambivalent as it can be interpreted as "bench meters with less than 5,5 digits don't exist" or "5,5 digits or more are only available in a bench meter". The BM869S does 5,5 digits in a handheld meter, but only on DC. |

Try that with a HH DMM. :P SDM3055 --- End quote --- Did you read the sampling speed speck for that bench multimeter? |
