It doesn't connect
The reasons why the logger does not connect to the software may be different. First you need to see what is the error message provided by the program. If the error message refers to the reading base or interface, like the one in the image below, it means that most likely the problems encountered are only found on the interface.
Therefore, you need to check that the cable is connected to the PC and the interface is connected correctly and that the drivers are installed correctly. For driver installation, refer to the instructions for the interface you have and the operating system on which you installed the software.
If, on the other hand, an error message refers to the data logger, as in the image below, follow the on-screen instructions to check its operation.
First of all, all the metal parts of both the data logger and the interface must be cleaned dry. Secondly, check that you have positioned the data logger correctly: the tip or the sensitive part always go upwards and in any case the face with the writings, with the laser marking, must always face downwards. Obviously, this does not apply to cylindrical loggers that must be positioned upright with the tip pointing upwards. Check that the metal parts of the interface adhere to the metal parts of the data logger. One of the main reasons the logger does not connect is due to a low battery. To verify this, follow the instructions in the video tutorial on the Tecnosoft YouTube channel to know how to open the logger correctly and remove the battery.
You can test the battery with a tester. If you have a spare battery, replace it. Remember to also replace the o-rings in addition to the battery, so as to ensure the seal of the logger under water and under pressure.
If the battery is charged or even after having replaced the logger it continues not to connect you can do a simple check with a tester.
