Ill correct my post, you have many 3522 on Ebay, and one seller link seems to have ton's of them ?? they sell around 1k$$ usd The lcd seems expensive ? Is it a good lcr ??? I tried to build an dc biais board for an Fluke 6304 i had, i had the chance to copy the 6306 dc biais board from an eevblog member, but the same parts used where very difficult to get, 150$ in parts only, no pcb made :( thks |

Hi, Imho, the 3522 is a decent meter, especially for me who works with audio most of the time. But also because of that I frequently need to measure chokes/transformer with DC current passing through, which then leads to the demand of the DC bias modules (the 9269 DC current module is preferred for this reason). I looked up and found your project with the 6304 meter and 9565 module, looks terrific but I'm not sure if they use the same principle with the Hioki. Thanks |

朋友们好! 哪位能告诉我如何进入日置3532-50数字电桥的的校准界面。不胜感谢! |

I cannot see the reference of these parts, in the 3531 classic MC1496D are used. Three DDS are present, one for sine/cosine generator and another one for undersampling clock generation. The sample and hold circuits seems identical (the area with blue through hole capacitors). I have delimited the different functional blocks. --- End quote --- Do you still have your 3532? I'm curious what in-circuit resistance readings you get for the group of resistors around R361. Thanks, Josh |
