Ideal for service, prototype and experimental use, this useful tool may be set at any resistance value from 1~11,111,110ohm, in one ohm increments. 28 individual slide switches allow the user to quickly and easily select resisstor values. Wave soldered, two layer PC board utilizes high quality 1% tolerance 1-3W resistors. Maximum stray internal resistance is 1 3ohm. Color coded binding posts provide resistor and ground connections. Passive device requires no power source.
