Hi all,
I have a Fluke 289 multimeter. I found it can not boot successfully today. When I install the battery case, the indicator under power key will flash some times, after about tens of seconds, the screen will display: "CAUTION, Critical FLASH memory error. Return meter to Fluke Service Center."
It looks like the firmware is lost.
Has anyone met the same issue? or do you have any idea about this issue?
