The GR 1455 Kelvin-Varley Voltage Dividers provide accurately known voltage ratios from 0.00001 to 1.00000 for use in many common measurements:
Voltage gain or attenuation
Linearity of potentiometers and other controls
Frequency response of audio and rf networks
Transformer turns ratio
Voltmeter calibration
Linearity better than 20 ppm (5-dial model)
Input impedance: for 1455-A 10 kΩ & 1455-B, 1455-BH 100 kΩ
High-frequency model, down 3 dB at 7.5 MHz
