12.1.1 Temperature measurement using two-colour/ratio mode
(Configuration layer:
C001
)
Parameter Function Explanation
E.TB.Q
No. of material con-
stants (array length)
Define the no.of elements you would like the
array of material constants to contain. Max.
array length is 10 (up to 10 constants).
EPS.Q
Emissivity ratio
Direct setting of material constant as emissivi-
ty ratio.
E.IDX
Set pyrometer to
material constant
Choose one of the stored constants from the
array, e.g.
E. 02,
for the application
E. 01
Assign material
constants
Customize the array: assign a value to each
of the material constants in the array.
