CAUTION

The power supply lines are internally connected. You can use either one
of them, but do not connect more than one supply voltage in permanent
installations. Temporary simultaneous use with the USB serial interface
cable or DM70 handheld dewpoint meter (which also provide operation
power) is OK.
