Kelvin-Varley IETLAB RV722 分压器

his standards grade Kelvin-Varley voltage divider is highly accurate, stable, and linear
instrument for use in many applications requiring accurately known voltage or current
ratios. In particular, the RV722 is especially appropriate for use in bridge circuits,
providing two arms of a bridge with a very well known ratio.
Applications include linearity determination, the measurement of
voltage and resistance, and the calibration of voltage, current, and resistance.
