Program to 0.001 when the emissivity
programming value is overshooting
from the minimum value and 1.999
when it is over shooting from the
maximum value.
No
Automatic emissivity

Program the emissivity value to1.000.
However, this programming is not

5.2 Overflow/underflow
●
“
oFL
” is displayed when the measured temperature is higher than (the maximum value of
measuring range + 20)ºC.
●
“
uFL
” is displayed when the measured temperature is lower than (the minimum value of
measuring range – 20)ºC.
5.3 Under flow display for two-color type radiation thermometer only:”CLP”
“CLP” is displayed when the measured temperature using two-color type radiation thermometer is
lower than minimum value of measuring range. And analog output is lower than 4mA.
This phenomenon occurs to etc. (1) View lacking (2) Measuring with lens cap
5.
Self-diagnostic function and
Overflow/underflow
On the items with Yes in the output column, the contact signal for the abnormal
condition is outputted from the contact output terminals (OFF at abnormal
condition).
This output is available when “
Self-diagnostic abnormal
” is selected in
[6.5.5 Contacts output item selection] in the engineering mode.
Caution
Reference
・
When measured temperature has not reached to the minimum value of measuring
range at the postperiod 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.
