Type 1454-AH is a four-stage voltage divider using the [[wikipedia:Kelvin–Varley divider|Kelvin–Varley divider]] circuit. The use of four special [[510|Type 510 resistance units]] achieve this. It features a constant 100 kΩ input resistance with a maximum input voltage 700 V at audio frequencies. | Type 1454-AH is a four-stage voltage divider using the [[wikipedia:Kelvin–Varley divider|Kelvin–Varley divider]] circuit.
