Let Ro; be the equivalent resistance of the combination a.» 
bi, and the ith thermistor resistance. The calculated values of 
Roi are Shown in table A2.

Although the compensated resistance for the specified temp- 
eratures have been obtained by calculation, these calculcations are 
made using measured values of resistance for the individual 
thermistors. 
Deviations from the mean fo; values were largest at 9°C. 
At this temperature, the greatest deviation (thermistor No. 2) was 
only 0.25 per cent from the mean. If desired, deviations at this 
end of the range could be made smaller by choosing 7. closer to 
IECR
