Norm,

I am 609 certified and have always charged by weight. I have looked HI and LOW for temperture/pressure charts like I used with R-12. For instance, at 90 deg ambiant temp the high side pressure should be XX psi and the low side should be XX psi. However I can't find anything similar for R-134. All I can find is what the pressure will be at a certain temp. Could you please explain how you charge a 134 system by the pressures.
Many thanks.
