When measuring the current out of the battery power supply
The microcontroller has 4 different states before going to sleep
It will start at 50ma then to 20ma, then to 5ma, then to 1 ma then the microcontroller will go to sleep at 10uA
When measuring the current using a DVM it really trips out the micro-controller and burns out the chip or certain inputs and outputs
Why?
What is the reason why measure current using a DVM is bad for microcontrollers and does a DVM in series adds a LOAD ( meter loading problem? ) to the circuit?
