Sorry about the problems being reported recently.
While I have no association with Bob of Fluke.l, he is using my design and he
was kind enough to send me one demo model, which I have yet to turn on.
In general, if the processor is not fried, there is very little that c

Hi Leigh:
Is the wiring to the monitor exposed such that you can touch it? I
think mine died because of static zap to the exposed wiring.

Fluke.L has sold 2 versions of the monitor.

Considering that there are two main components in the display, it could be
ither the microcontroller, the LCD display, or the cabling between the two.
I am not sure what you mean by swishing, but if shaking it fixes the problem
could also be temperature related.
