Circuit error in Vol 1 Ed Simon resistor measurement.

In Volume 1, Ed Simon has an article about measuring resistor distortion with a sensitive bridge setup. Unfortunately, the original bridge circuit in figure 1 has an error. The bottom of the bridge is shown returned to ground, however it should be returned to generator common. The corrected figure 1 is given below. The downloadable PDF of the article has been updated. Apologies to Mr. Simon!
