Does the sampler take the sample on a rolling 24 hour clock or does it reset itself every 24 hours?
The controller shows the actual rainfall that has been recorded within the past 24 hours. This is a rolling timeline in which each additional rainfall accumulation within the hour is added and the previous 24th hour is overwritten. The operator can reset the accumulated rainfall by selecting this command from the scrolling menu and pressing the Set button. Since this is a rolling 24-hour timeline, previous rainfall accumulation amounts will be cleared and a new 24-hour count started. The clock will continuously advance at all times, unless both batteries are disconnected or the unit is turned off.
