Hi I just Bought a Craftsman 82289 scope meter for $50 it seems to be off when testing capacitors for example a 2.2uf is reading 1.5 i have another cheap meter that reads 2.2 when testing the same cap. The AC & DC voltage reading is accurate so i was thinking maybe there is a way to adjust it with a pot that's inside I have done some research on it the meter seems to be made by extech and there is also a VOLTCRAFT version of it model GDM 704 & Extech 381265 they look the same as the craftsman someone had taken the volt craft one apart there are a lot of pots inside i wouldn't know which one to adjust without messing it up maybe someone else would know or maybe it's best just to leave well enough alone https://www-elektroda-pl.translate.goog/rtvforum/topic1678487.html?_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en&_x_tr_pto=wapp&_x_tr_hist=true |

Are you using the same test leads with both meters? Some of the difference might be there, at least. |

Hi yes i tried the same leads in both meters but it did not make a difference. maybe that's just the way the meter is made. or maybe it drifted i think it's almost 20yrs old if i had the same one to compare it to then i would know. |

I just picked up a Craftsman 82289 miniscope as well (don't ask me why). You got a better deal than I did. According to the silkscreen the meter is a rebrand of the WENS33N. Amazingly it turns out there's a page dedicated to the WENS33N (in Japanese): - https://hirokun.jp/av/wens_33n.html - google translated: https://hirokun-jp.translate.goog/av/wens_33n.html?_x_tr_sl=ja&_x_tr_tl=en&_x_tr_hl=en&_x_tr_pto=wapp The person who wrote that info page also posted calibration instructions with schematics: - https://hirokun.jp/av/wens_33n_sch.pdf So you might be in luck as far as getting the capacitance adjusted. Please post details on how it goes! |

Thanks for posting that. Now I just need to figure out how to get it apart. |
