6.4 Operating mode
6.4.1 Emissivity programming
If the emissivity of object measured is low, the temperature displayed becomes lower than the exact
temperature and the emissivity is to be compensated.
1) To program the emissivity value, press
SEL
key in the
measurement mode screen until “
” appears in the sub marker
as shown in the right figure.
2) By pressing
key, the most significant digit of the sub
display will blink.
3) Use
△
or
▽
key to program the desired value.
4) To shift to the next lower digit, press
key. The next lower
digit will blink.
5) Repeat the above procedure of (3) and (4) up to the least
significant digit for programming (4 digits).
6) To activate this programming, press
ENT
key.
6.4.2 Automatic emissivity calculation
The emissivity is automatically calculated when you coincident the measured value to the reference
temperature value entered by function keys or by an analog input (option).
6.4.2-1 Automatic emissivity calculation(Internal )
:Input of reference temperature
In the measurement mode, the emissivity is automatically calculated by entering the reference
temperature value measured by a thermocouple or other sensor in advance.
1) To program the reference temperature value, press
SEL
key in
the measurement mode screen until “
Auto
” appears in the sub
display as shown in the right figure.
2) By pressing
key, the most significant digit of the main
display will blink.
3) Use
△
or
▽
key to program the desired value.
4) To shift to the next lower digit, press
key.
The next lower digit will blink.
5) Repeat the above procedure of (3) and (4) up to the least
significant digit for programming (4 digits).
6) To activate this programming, press
ENT
key.
The programmable range is
0.050
to
1.999.
The default value is
1.000.
