The 752A reference divider is an accurate 10:1 and 100:1 divider specifically designed for comparing direct voltage readings from various sources to a 10-V voltage reference standard such as a 732B.
Internal switching allows calibration of the 100-mV, 1-V, 10-V, 100-V, and 1000-V ranges of a voltage calibrator with a 10-V standard such as the 732B without changing connections.
Using a self-calibration procedure, you can compensate for long-term changes in the value of the divider resistors by switching between different Wheatstone bridge configurations.
