Every weather station has its own measurement range, as does the WS-1300. If the value is below the measurement range, the weather station will display LL/LO. If the value is above this range, the weather station will display HH/HI.
Please note that when the outdoor unit is in the rain, the humidity can go up to 100% and thus indicate HH/HI.
If you feel that the measured value is not correct, you should compare it with, for example, the KNMI station in your area. If the value deviates a lot, there seems to be a defect in the sensor.
If your weather station is still under guarantee, you should report the fault to www.service-hesdo.nl. If your weather station is not under warranty, you can order spare parts for your weather station on our site www.alectohome.nl.
