Title: FLUKE 741B
Post by: lionelkjh on October 31, 2017, 01:18:47 pm

Hello everyone! I recovered a FLUKE 741B calibrator in very good condition, but failed. Opening it, I realized that it was missing the flash memory removed by the former owner, who was probably defecteueuse. Could someone tell me what was his name? And, most importantly: how to do the calibrator data ?? (unless someone has the file, by chance!) .. Thank you to all who can help me in this troubleshooting |O

I don't know if there is a service manual available but here are the User (http://assets.fluke.com/manuals/741b743bumeng0100.pdf) and Calibration (http://assets.fluke.com/manuals/74x_____cmeng0200.pdf) manuals for it. Unfortunately I've never used one so I don't have anything more than this (and I suspect you already have these).

Good evening; I have already looked in the service manual before posting on this forum, there is no schema or nomenclature on integrated circuits. Cdt |O

I can open a Fluke 743B (which seems the same calibrator) for look inside. Can you communicate the identifier of the missing component?
