Dear Ron, There should be no confusion. Your spot meter reading appears to be correct since my pentax spot meter gives the same reading. You can fine tune your camera meter by reading a grey card in sun. If you are using 100 asa film, proper bright sunlight exposure should be 1/125 sec at f16. Keep your camera in hyp.manual mode and set this exposure value (by setting shutter speed and aperture values manually)and then adjust film asa setting on your camera to find which asa matches with this expoure.Regards,Hansraj.
