This video demonstrates how to insert multimeter leads in series with the power ground wire to measure the total current drain of the data logger. Measuring current drain on a data logger is important for estimating battery life and ensuring that the data logger remains operational for the intended duration without requiring frequent battery replacements. Also, a higher than expected current drain can indicate issues or malfunctions within the data logger or its connected sensors.
