ATTENTION
Decade Resistance Boxes are usually not accurate enough to meet the 0.02% accuracy
requirement noted in Table 5-2. This can be overcome by performing a four-wire resistance
measurement with a precision DMM and then adjusting the Decade Box to the correct zero and
span resistance values as given in
Table 5-1. Determine the proper zero and span resistance
settings prior to attaching the Decade Box to the instrument. For best accuracy, measure with
the DMM connected to the wire ends rather than directly to the Decade Box.
