APPENDIX B: DETAILED TEST METHODOLOGY
Measuring surface temperature
Test requirements
 Fluke® 2680A Data Acquisition System
 PassMark® BurnInTest Professional
 Linpack benchmark
Measuring system temperature and power while idle
Setting up the test
1. Set the power plan to the manufacturer’s default setting. Set the display brightness to 100 percent:
a. Click Start.
b. In the Start menu’s quick search field, type Power Options
c. Move the Screen brightness slider all the way to the right.
2. Set the remaining power plan settings as follows:
 Dim the display: Never
 Turn off the display: Never
 Put the computer to sleep: Never
3. Disable the screen saver.
4. Place the workstation, mouse, keyboard, and display in a windowless, climate-controlled room.
5. Attach a Type T thermocouple to the exterior of the workstation at the following locations:
 Front center
 Top
 Side opposite the motherboard
 Side closest to the motherboard
 Back in center of power supply exhaust
6. Configure the Fluke 2680A Data Acquisition System to take measurements from the temperature
probes and one ambient temperature probe using the Fluke DAQ software.
a. Connect the Type T thermocouples to channels in the Fluke Fast Analog Input module (FAI).
b. In the Fluke DAQ software, click each surface temperature channel, select Thermocouple from
the list of Functions, and choose T from the list of ranges.
c. Label each channel with the location associated with each thermocouple.
d. In the Fluke DAQ software, click the ambient temperature channel, select Thermocouple from
the list of Functions, and choose T from the list of ranges.
e. Label this channel Ambient.
7. While running each test, use a Fluke 2680A Data Acquisition System to monitor ambient and
temperature at each interior and exterior point.
8. Connect the power cord from the workstation to the Extech Instruments 380803 Power Analyzer’s
DC output load power outlet.
9. Plug the power cord from the Power Analyzer’s DC input voltage connection into a power outlet.
10. Connect a separate host computer to the Power Analyzer using an RS-232 cable. This computer will
monitor and collect the power measurement data.
11. Turn on the Extech Power Analyzer by pressing the green On/Off button.
12. Turn on the host computer.
13. Insert the Extech software installation CD into the host computer, and install the software.
