That is close to what should be the maximum UV reading when using UV_Transmission = 100. If you are having a sunny day without cloud on the sky, that reading may not be to far from reality (its Spring on NZ now I think).
What are the average UV readings at nearby weather stations? Use WU if needed.
Make sure the sensor is pointing to the sky in horizontal position, not facing the sun.
