The accuracy classes refer to the measuring inputs of the device. Upstream transformers can influence the accuracy. For low-power current transformers, we recommend using at least 10 A primary current and a maximum cable length of 5 m. Suitable current transformers can be found in our catalog or at www.janitza.com.
