My Diode calibration since May 2002.

"Have fitted a Diode Reader made by Hoot. to a ECS K7S8A volt modded motherboard to take the temperature of a Morgan1100.* The custom-made reader has a 15" long shielded cable to the SMBus header plug which is plugged into the header on a P3V4X motherboarded Celeron PC.Temperatures are read using MBM5 on the Celeron PC.
I checked the the Reader's sensitivity/calibration by pumping water at temps 18-45c through a waterblock on the Unpowered Morgan1100 and compared the Diode Reader's temp with that of the reservoir water measured with a greenhouse/household bulb thermometer. The Diode reader gave temps consistently ~ 1.5c below that of the of the household/greenhouse thermometer throughout the temp range.This was the case even when the resevoir water temp(18c thermometer read) was below ambient(23c).I did not compensate for the difference in reading because the greenhouse/household thermometer is of unproven accuracy."
