Note:
Please note that the optical profiles show nominal dimensions. The spot size di-
ameter or the focal distance may be slightly different due to lens tolerances.
Note:
The InfraWin program includes a Spot size calculator that roughly
estimates the unknown values. The values represented here are for reference pur-
poses.
Spot sizes for intermediate distances, that are not shown on the optical profiles, may be calculated using the
following formula:

Instrument settings
Before using the pyrometer some basic settings should be taken. The basic settings can be done at the py-
rometer itself, some further settings can be done via interface and software InfraWin.
Settings at the instrument: The basic settings are emissivity, exposure time, analog output. These settings
can be adjusted at the pyrometer only in offline mode (see 8.2 Online- / offline mode (ONL/OFFL)).
Settings via serial interface: The pyrometer is equipped with a serial interface RS232 or RS485 (corre-
sponding to the ordered version) which can be used for connection to a PC. With the standard software In-
fraWin (or a self written communication software) the following settings can be done (the pyrometer must be
in online mode (ONL) to use this functions, see 8.2): emissivity, exposure time, analog output, maximum
value storage, minimum value storage, reading of the instrument’s internal temperature, setting of an ad-
dress for bus control with RS485 interface, setting of the baud rate, function for compensating of the off-set
of the ambient temperature). Additionally InfraWin enables the temperature display and analysis.

Switches at the instrument
The controls / switches are located
under the rear cover of the pyrometer
and can be accessed by removing the
rear cover in the following way:
1. Disconnect the electrical
connection
2. Unscrew the rear screws with a
2.5 mm allen screw
3. Take the cover off, making sure it
remains straight (without bending
or twisting it).
Assembling:
When reassembling the cover, insert it carefully into the guide pins and then fasten it with the screws. The
connector cable can now be plugged in.
