High power consumption
I just measured the current consumption (from a lab power supply replacing the battery, not from USB) of my DM42 loaded with different programs (because I already have a battery low indication).
Within DMCP or the DM42 firmware, the current is ~25-30 µA in idle, some value in the 2-5 mA during activity (the duration is not enough for my multimeter reading to stabilize), and at worst 6.3-7 mA during flash erasing/writing. The consumption in off state is too low, I couldn't measure it reliably.
With C43 and Jaco's special WP43S, at power on the consumption immediately rises to a steady 4.6-4.7 mA, equivalent to continually running a program at full speed in the DM42. Power off is the same as for DMCP.
Is this a known fact ? I didn't find anything in the forums. And if yes, is the reason known ?
