Stopping your data logger
All HOBO and StowAway data loggers shut off when the memory is full (unless wrap-around is selected) or the data is downloaded to a computer. Once the data is downloaded to the computer, the data logger is in off mode and will need to be relaunched to continue data collection. If the data logger you are using is shuttle-compatible and you are downloading to a shuttle, the shuttle will automatically relaunch the data logger using the previous settings.

Protecting data loggers from electrical discharge (ESD)
A discharge of static electricity may cause a running data logger to stop recording. Precautions should be taken to prevent this while handling the data logger. Discharges may occur when there is a charge difference between the data logger and a cable being connected to it or when a person touches an exposed jack.

Drying a wet circuit board
If possible, remove the board from the case and the battery from the board. Dry the board completely using a hair dryer. If the board was exposed to salt water, rinse the board with fresh water and then dry the board. You may try inserting a new battery and downloading the data. If you are unable to access the data, or see any sign of corrosion or tarnishing on the board, contact the place of purchase for a return number. The data may be retrievable, and the data logger may be repairable. Charges will apply and are dependent on the amount of damage.

Possibility of exposure to chemicals or chemical vapors
This is dependent on the data logger you are using and the chemical and/or concentration of the chemical to which the data logger is exposed. Many chemicals will have an adverse effect on the data loggers and/or the sensors that the loggers utilize. Contact your authorized sales representative with questions regarding specific chemical contact with the data logger that you are using.

Light on/off data loggers recording more states than are actually occurring
If you are monitoring fluorescent lights, part of what you are seeing may be due to a fairly common attribute of fluorescent lights. When the filaments of a fluorescent lamp and the gas inside the lamp are not up to the normal running temperature (normally the first few minutes after startup), they are likely to flicker a bit.
