This made me concerned about the CS made with DI water, so I did some
measuring. Using a COM-100 the PPM immediately after making the CS
was 8.8. Two days later the PPM is 5.6, so there is a stability
problem with CS made from DI water. I measured some older CS made
with distiller water and got these readings:
7.6 to 7.1
8.0 to 6.9
8.0 to 7.5
so CS made with distilled water is more stable than CS made with DI
water. I will continue to experiment with DI water.
