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.

Event data logging vs State data logging
A HOBO Event data logger records the opening of the contacts only. It does not record the closing. A HOBO State data logger records changes in the state - both the opening and closing of the switch, (door open/close, light on/off, etc.). Event data will accumulate over time and totalize whereas state data will indicate a high or low position. Some HOBO series support both state and event data logging.

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.

Data logger is shutting off prematurely
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.
