| Keysight's new 34465A (6.5 digit) and 34470A (7.5 digit) bench multimeters |

| Dr. Frank:
radio Flash: Thanks for these great photos! Please make a side shot of R324, showing its imprints on both sides. it's assumed to be a Vishay metal foil resistor, which would tell something about (better) Ohm stability and maybe the "Autocal" feature. (Ohm stability 34461A: 80ppm/yr. // 34465 + 34470: 20ppm/yr.) Frank |

On all my newer 34401A I see yellow transparent tape on the larger electrolytic capacitors (heat protection during production may be?). Interesting, that we do not see this tape in either the 34460A or the 34465A boars. Thanks for the great pictures. |

Here's a photo with the shield in place. This is the only shield in the meter-there's not a separate one for the fan/regulator. |

I'm at a bit of a loss as to why anyone would pay for the MEM upgrade, when the 50,000 point limit of the standard meter doesn't apply if you're logging to a file on a USB stick. I checked this morning; 70,000 points taken at 3msec intervals, no problem at all. --- End quote --- Can you share a log file? How many significant digits are there? (like this +3.31785468E+00,+3.61554515E+00) Data log mode The maximum reading rate is 1000 readings/s (max. 100 hours) "Digitizing" from what I read they mean fast reading like 5000 readings/s |

Here's a 10 sample log. Probes are connected to a 9V battery. Meter is set to the 10V range, acquisition time is set to 200us, and sample interval is set to 2ms, both of which are as short as I can get. If anyone knows how to sample at 1ms intervals, I'd be interested to know what I've missed. --- Code: ---Start date:,03/10/2015,Start time:,15:09:42.910 Sample interval:,0.002000 Reading #,Reading 1,+8.80413134E+00 2,+8.80414814E+00 3,+8.80423098E+00 4,+8.80415278E+00 5,+8.80414582E+00 6,+8.80419101E+00 7,+8.80415741E+00 8,+8.80417653E+00 9,+8.80417885E+00 10,+8.80416958E+00 --- End code --- Edit: here's another log with the meter set to 1 PLC acquisition time and 0.5 sec sample interval: --- Code: ---Start date:,03/10/2015,Start time:,15:18:38.130 Sample interval:,0.500000 Reading #,Reading 1,+8.80401932E+00 2,+8.80401939E+00 3,+8.80402039E+00 4,+8.80401911E+00 5,+8.80401959E+00 6,+8.80401877E+00 7,+8.80401866E+00 8,+8.80401888E+00 9,+8.80402165E+00 10,+8.80401964E+00 --- End code --- |
