must be confirmed by pushing the ENT key. If it is not confirmed
with ENT, the instrument will operate with the previous
parameter value. If no key is pressed for approx. 30 s, the display
Limit contacts:
Two limit switches can be set. If the measuring temperature
exceeds the adjusted limit contact temperature, the LED S1 or S2
displays the switch status.
Scale °C or °F:
The LED indicates the temperature scale in °C or °F.
Parameter indicator:
LED’s indicate which pyrometer parameter is selected for reading
or changing.

4.4 Built-in Scanner (IS 12-S and IGA 12-S)
The pyrometers IS 12-S and IGA 12-S with fixed optics are
equipped with a scanning mechanism built into the
pyrometer housing which moves the measuring beam up
and down. In combination with the pyrometer's
maximum value storage (peak picker), the scanner is
optimally used for scanning of thin oscillating wires, for
finding scale-free spots on heavily scaled surfaces or for
measuring small, hot objects whose position is not exactly
determined.
All instruments are equipped with a thru-lens view finder
and an additional laser targeting light for exact
alignment to the position of the measuring object. The thru-lens view finder doesn’t follow the
scanning mirror movement; it always shows the center of the scanning amplitude. The laser
targeting light follows the scanning mirror movement and always shows the position of the
measuring spot. The moving measuring beam does not increase the spot sizes due to the very
fast exposure time of the pyrometers.
