9.2 Overflow/underflow indication
“
oFL” is displayed when the measured temperature is higher than the maximum value of measuring
range + 20ºC.
“
uFL
”
is displayed when the measured temperature is lower than the minimum value of measuring range

.
9.3 Clamp indication
In the case of 2 color radiation thermometer, a temperature indication department becomes "CLP", if it
becomes lower than approximately 10% of radiant energy at the measurement scale lower limit
temperature. In this case, the current output is 3.8mA.
This phenomenon occurs to etc. (1) View lacking (2) Measuring with lens cap
Overflow indication
Underflow indication
Clamp indication
Reference
When measured temperature has not reached to the minimum value of measuring
range at the post period of measurement start, 'CLP' or 'UFL' are displayed.
The view lacking is expected, in the case that this phenomenon occurred although
the temperature of the measurement objects is rising.
