Specification:
a. Base Station : This unit serves as the platform for carrying out student experiments. The unit contains two ammeters and two voltmeters which are used to do the voltage and current measurement during the experiments. A clear diagram of a transformer is shown on the base station and is completed with 4mm terminal connections to build transformer circuits. Circuit protection is provided to prevent short circuit and over current conditions.
