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.
