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.

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.

Data loss and recovery

There are two common reasons for data loss:

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.
