The 752A Reference Divider sets the standard for ratio accuracy and ease of use. It offers two divider outputs, 10:1 and 100:1 with output uncertainties of less than 0.2 ppm and 0.5 ppm respectively.
Before each use, 752A reference dividers are easily calibrated with only a stable source and a null detector. The entire procedure takes only five minutes and does not require external standards.
The calibration procedure compensates for long term changes in value of the divider resistors. The upper leg of the divider is configured into three equal groups, which, when placed in parallel, form a resistor of equal value to the output resistor. These two resistors form one half of a Wheatstone bridge. The other half is composed of two calibration resistors whose positions can be interchanged in the circuit. This interchange allows correction for any difference in the values of the calibration resistors through use of the BALANCE knob on the front panel. The upper leg resistors are then matched to the output resistor with the 10:1 or 100:1 potentiometers respectively.
