Title: Fluke Hart 1590 Repair
Post by: kevinbrennan on August 12, 2024, 05:15:59 pm

Good Morning. I'm searching for repair docs for a fluke hart 1590 super thermometer. No longer supported by fluke.
Specifically I have a dead computer section of the instrument, if anyone with docs or knowledge of the instrument can share would be highly appreciated.
Note the 1575 docs would help as well, which is a lower precision instrument in the same family.

Best Regards,
Kevin B

 Hi Kevin I also have a 1590 on my lab to do a repair and need the schematic. If you found it will be very helpful. About 2 years ago the lcd was damaged and with some work on the bios of the video board i could use the instrument with a vga monitor. On another repair the U3 74ls08 of the isa interface board had to be replaced, take a look on this board and maybe it will be your problem.
