I have received quite a bit of positive feedback since I wrote about the hacks on DTM0660L based multimeters last time. So I went ahead and translated the original Chinese datasheet into English and the PDF datasheet is linked below:

If you spot any inconsistencies, please let me know so I can update the document.
Thank very much :-). Are all details of the eeprom translated? I’m playing around with a DTM0660 based DMM, and trying to figure out how to get the frequency measurement to be correct after changing the xtal oscillator for another one. And I can’t for the life of me find the original Chinese datasheet.
I didn’t see any mentioning for crystal selection in the original manual :(
Thanks for checking it out though :). I desperately tried changing almost every likely value in the eeprom, does not seem like there’s an option to make the meter behave with a different xtal. Now my meter has a turbo button that swaps in a 8mhz xtal for double speed :D.
