( 1 ) When the partial pressure is greater than the value RUE01 and RE03 12.5V, UE01 conduction , UE02 off, current flows from the coil 27V → UE01 c, e very → RE01 → 12V, the resistance change UE01 adjusted RVE01 the degree of conduction , thus changing the size of the current in the coil , the magnetic field changes the size of the horizontal direction , the rotational angle of the electron beam is changed , to the spin state of the image object .SEgservice manual download site
( 2 ) when the partial pressure is less than the value RUE01 and RE03 11.5V, UE02 conduction , UE01 off, current flows from the coil 12V → RE01 → UE02 e, c → ground electrode , so as to achieve a change in the direction of the current in the coil the purpose of changing the direction of the horizontal magnetic field, the direction of rotation of the electron beam is changed , changing the image to achieve the rotation direction of the object shape . Similarly , by adjusting the degree of conduction resistance RVE01 change UE01 , can change the size of the current in the coil , the rotational angle of the electron beam is changed , to the opposite direction of rotation of the object image .
