Nettet25. jun. 2024 · Moving iron Instrument or Moving iron meter is used to measure the current and voltage of AC and DC. They are non-directional. The working principle depends upon the movement of iron attracted by the magnetic field towards it and repulsion between them. The magnetic field is produced by the current in the coil. Nettetthe desired sensitivity, this instrument will have a non linear meter scale. The FSD input voltage, source impedance to some extent, and all of the detector components affect the scale shape. The main factors are the FSD input voltage, diode characteristics, capacitor and load resistance. Fig 1: LTSPICE model
