Produto muito útil e interessante. Ideal para monitorizar a rede elétrica numa bancada de trabalho. Excelente preço. Eu escolhi o azul mas as restantes cores também parecem bem interessantes.
Dos testes que fiz, concluí que a precisão da indicação da tensão da rede e da frequência é excelente. Quanto à indicação da corrente, já não é tão precisa: verifiquei que existe uma diferença, para mais, de cerca de 300mA. Fiz várias experiências com o tipo de fio e com o número de voltas do fio em que queremos medir a corrente. Só é necessária uma volta (fio multifilar ou rígido). Mais voltas aumenta o erro da indicação. Não sei se o circuito tem algum tipo de calibração (é pena que estes produtos não venham acompanhados de algumas instruções).
Ainda assim, estou muito satisfeito. Recomendo.
