Kelvin-Varley Voltage divider circuit - more economical than the DP-500.

Operates in the same way as the DP-500, except that it has an additional, but variable resistance in series with the wiper arm which goes to zero at the full scale and zero settings.

Use this type where the wiper is input into a high input impedance of if it does not affect the particular application; The KVD-500 is suitable for most voltage divider applications. See the KVD-600/KVD-700 for comparison and additional information.

• Suitable for use in voltage and current dividers
• Eliminates the need for dials & multi-turn potentiometers
• 1, 2, 3, 4, 5, and 6 decade units are available
