Check battery voltage
To measure the battery voltage of a data logger without a load, that is, when the battery is removed from the data halogger, open the device following the instructions (available on the Tecnosoft YouTube channel). A tester is required to perform the check and the tips must be connected for voltage verification. Turn it on and possibly set it to read the Vs. Place the tips on both sides, positive and negative, of the battery and read the voltage on the display.
