Leeds And Northrup 7592

The 7592 Volt Box is used to extend the range of potentiometers in a variety of applications in which the voltages exceed the maximum range of the potentiometer. Exceptional design features include: Direct reading of all range settings An OPEN Position on the range switch to disconnect line connections (no need to remove leadwires) Large total resistance (750 ohms/volt), assuring small current drain on the unknown voltage Acrylonitrilestyrene copolymer insulated binding posts mounted on the metal top plate High-quality Type 31 silver-allow rotary selector switch Woven manganin wire resistors. For use up to 750 volts
