Descripcion
El DMM Celebrada GDM -300/ 400 series de mano son un diseńo compacto, de
alta precisión, con pilas serie multímetro diseńado para satisfacer la mayor
parte de las necesidades diarias de los ingenieros de diseńo, así como los
ingenieros de servicio. El diseńo de la serie GDM -300/ 400 está impulsado por
características orientadas a móviles, como apagado automático para preservar la
vida de la batería, una pantalla de retroiluminación grande para una
visualización nítida , un selector rotativo y botones claros empuje para
facilitar la operación . Las funciones básicas se ajustan a la profundidad de
sobremesa multímetros: entrada de corriente protegidas por fusible, RMS real
para mediciones precisas de CA , que van Auto , Ciclo de trabajo y modo
relativo. Estos dispositivos compactos, confiables y económicos son ideales
para cualquier Ingeniero.
