LED FLASHING MODES
EL-USB-2 features 2 bi-colour LEDs; one LED represents temperature measurement, the other represents RH. Each is clearly marked on
the logger. To save power, the status indication alternates between the two channels every 10 seconds. First you will see the status of the
temperature logging and 10 seconds later you will see the status of the RH logging and so on.
