Step 3 – Enter the calibration material name.
Step 4 – Enter a description for the calibration material (optional).
Step 5 – Click the Add button twice in the Cal Material Values frame.
Step 6 – Select Effusivity for the first row.
Step 7 – Enter the calculated effusivity value.
The thermal effusivity value is calculated from the following equation:
Cp
k
Eff
(W
√
s/m
2
K)
Where k is the thermal conductivity (W/m
∙
K),
ρ is the density
(kg/m
3
), and Cp is the Heat Capacity
(J/Kg/K).
Note: 1 J = 1 W

Step 8 – Select Conductivity for the second row.
Step 9 – Enter the literature thermal conductivity value.
Step 10 – Click the Save button.

Calibration Material Groups
Calibration material groups contain at least three different materials of similar properties.
Preloaded groups include liquids and powders, foams, polymers, ceramics, and metals. These
records cannot be edited. Any user created calibration material group can be edited in the
normal way.
Note: Permission to create and edit calibration material groups must be granted by the
system administrator.
Step 1 – Open the Calibration Material Group table.
Click the Calibration option from the Manage menu, and Calibration Material Group option from
the Calibration submenu.
Step 2 – Click the Add button.
