There is a small bug in early HOBO Water Temp Pro loggers that results in premature starting in some cases when using the delayed-start feature. With the affected loggers there is a 0.4% chance they will start up to 4.3 minutes early, and a 0.4% chance they will start up to 18.2 hours early. If premature delayed-start occurs, all measurements are taken at the correct sampling rate and stored with the actual times they were taken, but there will be extra readings at the beginning of the data file.
