| BK Precision LCR meter 879b with ADC failure |

Hello everybody, I allways wanted an decent LCR-Meter. Now I found an faulty BK Precision 879b on eBay; Dave made an Video of it some time ago: I did't buy it yet; it's on sale right now. The display of this faulty device shows Err E02: the manual says that this is an ADC failure. On the internet I found out, that this accours when you try to measure capacitance of a charged cap :palm: As an beginner I would like to ask: how big is the chance to repair this meter? I can't find any schematics or service manual, so I can't imagine what could be wrong. :( Sorry that I don't post the url of the auction. I'm afraid that could affect the final cost. Thanks :) |

As cheap as the DE-5000 LCR meters are available now (aprox $125.00), I would seriously consider one over the BK. |

There's no information how severe the damage is, it could be a blown fuse, it could be beyond economical repair. Even if you managed to repair it, you probably need to calibrate the meter. |
