LED FLASHING MODES
EL-USB-2-LCD 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.
