A quick temp-accuracy check (ice bath)
We receive many calls requesting information on how to calibrate our data loggers. While our data loggers cannot be calibrated, you can certainly check to see if the data loggers are recording within their specifications. Ideally, testing should be done in a controlled environment. Unfortunately, not everyone has access to this type of environment.

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.

Maximum sensor cable length
The entire network (all sensors combined) cannot exceed 100 meters. As long as your total cable length is below this, it does not matter how you designate the individual cable lengths. It is important to insure that the connections are weatherproof.

Rapid battery consumption (outdoor loggers)
All Users: Check both the logging and the sampling interval to make sure they are greater than one-minute intervals. For example, with a sampling interval of one second, the HOBO logger is constantly on and there is a constant drain to the batteries. If your application calls for such an interval, you may need to replace the batteries more frequently

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.
