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.

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.

Optic logger communication problems
All Users: HOBO Optic data loggers must be inserted into the Base Station (or Shuttle) using the appropriate coupler for that logger in order for the computer to detect them. Note: HOBOware will not detect the Base Station alone as an attached USB device.
Check to make sure that the coupler is positioned properly and the magnet end is closest to the data logger, not the Base Station or the Optic Shuttle.

Logger power failure and data loss
The data is stored on non-volatile EEPROM. For data loggers with external batteries: change batteries and offload data, then relaunch normally. For data loggers with internal batteries: as long as the EEPROM has not been damaged, the data can be retrieved by Onset. Please contact the place of purchase for a return authorization number and request data back service.

Cleaning Optic StowAway/StowAway TidbiT data loggers
Do not use any type of chemical on an Optic or TidbiT data logger! You can wash the data logger with a mild soap and warm water solution. If the data logger has a mineral or algae build-up that will not come clean, do not scrape it off. Instead, use a plastic polish, such as Novice.
