You can disable the auto power-off if you want - see p118

or you can change the timeout period.

Great post.

Yes, you have to make a little check list when doing testing.

Trust but verify power supplies, input voltages and wire connections.

Sometimes the magic smoke is the last thing that escapes and the damage has already been done.

Rule of thumb, always adjust the voltage from zero to operating level.

Never assume that it is at the correct level until you measure that it is there.
