Why is the scale of a megger calibrated in megaohms?
Right Answer is:
To indicate resistance
The megger is used for the measurement of high resistance and insulation resistance. The high resistance to be tested is connected between terminals of megger. The opposing torques of the coils balance each other so that pointer attains a stationary position at some intermediate point on the scale. The scale is calibrated in megaohms so that the resistance is directly indicated by the pointer.
