*V O M used to obtain these measurements was a 2 0 ,0 0 0 12/volt dc meter with a center-scale reading of
4.5 k on the 1,0 00 12 scale. For the 1,000 12 scale, center-scale deflection current is 160 fia and 320 fia at
full scale.

Ohmmeter leads are connected first in one direction, then the other, to obtain the two readings.
