If the Allowable Measurement Range of Each Range is Significantly
Exceeded
"OVER" or "-OVER" is displayed for the numerical value or cursor value and the cal-
culated value or saved data is handled as a full scale value.
Refer to “ LR8432-20 Measurement Values” (p. A13).
Refer to “Appendix 12 Heat Flow” (p. A42) for information about heat flow.
How to Select the Measurement Range
The allowable measurement range is determined
depending on the selected measurement range
and the sensitivity constant.
The allowable measurement range is expressed
in the following equation.
Allowable measurement range of selected mea-
surement range [W/m
2
] = ± (Selected measure-
ment range / Sensitivity constant of sensor [mV/
W•m
-2
])
Example: When the measurement range is set to
10 mV and the sensitivity constant is 0.012 mV/
W•m
-2
Allowable measurement range (extent) of
selected measurement range = ± (10 mV/0.012
mV/W•m
-2
)=± 833.333 W/m

After setting the range and the sensitivity con-
stant, configure the other settings as shown in
the right to verify the allowable measurement
range without performing any calculations.
