| - | | + | There are two options for running battery impedance measurements on the EVAl-AD5941BATZ. The first is using SensorPal GUI tool. SensorPal provides an intuitive interface that allows the user to configure and update parameters such as frequency range and view measurement results in Nyquist form without needing to downlaod or use an IDE such as Keil. This option is best for rapid prototyping and measurement verification. |
