Abstract :
This paper describes a new solid state circuit for resistance measurement in the range 1-108 ¿. The advantages of this circuit include: reliability, simplicity of design and use, low cost, and the fact that resistance scale is linear. The accuracy of measurement is around ±2 percent of reading at full-scale value in the range 1-106 ¿ and ±6 percent of reading at 10 M¿ and 100 Mg. This circuit is temperature-compensated and exhibits good operational stability. The constructional cost of the instrument is about $41.00.
