D.3 Thermal calibration and controls
It is recommended that full and routine calibration of temperature measurement
equipment be performed before attempting to perform case temperature
measurements. Intel recommends checking the meter probe set against known
standards. This should be done at 0 ºC (using ice bath or other stable temperature
source) and at an elevated temperature, around 80 ºC (using an appropriate
temperature source).
Wire gauge and length also should be considered as some less expensive
measurement systems are heavily impacted by impedance. There are numerous
resources available throughout the industry to assist with implementation of proper
controls for thermal measurements.
NOTES:
1. It is recommended to follow company standard procedures and wear safety
items like glasses for cutting the IHS and gloves for chemical handling.
2. Ask your Intel field sales representative if you need assistance to groove
and/or install a thermocouple according to the reference process.
