End caps are force fitted and termination wires are welded to the end caps. The element is adjusted to the required resistance value by a helical cut; finally a cement protection is applied to the resistor body prior to marking with indelible ink. Marking MO1/2S, MO1S, MO2S and MO3S resistors are colour coded with four bands. IEC 62 colours are used. For larger sizes type reference, resistance value and tolerance are legend marked. The resistance value marking conforms to lEC 62. Solvent Res...
