Frequently Asked Questions

The battery will operate the logger for 5 years at room temperature. Operation of the logger at the temperature extremes, in real-time mode for prolonged periods, or sample intervals of less than a minute, will significantly reduce battery life.

Please contact the factory if the battery requires replacement. The battery level monitor on the “SETUP” screen displays the battery voltage and a low battery warning when replacement is needed

There is a LED indicator located on the front lower right corner of the unit. This indicator will flash red every 10 seconds ONLY when the unit is sampling and operating properly. If the indicator is not flashing, please verify the following:

The logger memory may be full; download the data and clear the memory.

Sampling may not be activated. To start sampling clear the memory.

Condensation may have formed on the unit. Place unit in a warm dry environment for 24 hrs.

Clear memory and try again. These loggers are designed for use in a non-condensing environment. If the environment creates condensation, try placing the unit (temperature only models) in a small sealed plastic bag to protect it from condensation.

Verify that you have the correct version of Dickson software installed on your PC. Version 10 or higher is required.

Verify that the correct port is selected: From the main Dicksonware screen, click on Logger then Communication, a black dot will appear next to the selected port. You may need to select a different port.

You may need to relocate the download cable to another USB port and possibly try changing the port again in DicksonWare.

If communication has not been established with the previous steps, you may need to open the logger and remove the battery for a few seconds and then try all ports and cable combinations again (this will not cause the unit to lose any logged data, but you will have to clear the logger to restart the logging process, this is done using DicksonWare).

If possible, try another PC
