(only available via interface commands, see 14, Data format UPP ® )
Using a pyrometer with RS485 it is possible that the connection is not fast enough to
receive the pyrometer’s answer to an instruction of the master. In this case a wait time
can be set to slow down the data transfer (e.g.: tw = 02 at a baud rate 9600 means a
wait time of
2 /
9600
sec).

Internal temperature of the pyrometer
The internal temperature of the pyrometer can be read via interface. It is a few degrees above the ambient
temperature due to the warming generated by the pyrometer electronics.

Avoiding reading errors caused by faulty assembly
To avoid reading errors, please note the following points when mounting the pyrometer:
1. The diameter of the measuring object cannot be smaller than the pyrometer’s spot size (see section 7,
Optics).
2. A source of radiation behind or around the measuring object can influence the result. If the object is
transparent or partly transparent another material behind the object could transmit its radiation to the py-
rometer as well. In this case the location of the pyrometer should be changed, or, if the background ra-
diation remains constant it can be compensated for by changing the emissivity setting respectively.
3. Please take into account that radiation, from other hot materials around the measured object, can be
reflected by these materials and influence the result. If the measured object has a low emissivity, the
temperature measured will be mainly that from the reflected object - not from the intended measured ob-
ject itself. To prevent ambient radiation from reaching the spot area, a mounting tube should be used.
The mounting tube should be placed as near as possible to the measured object so that the tube’s
shadow blocks out all the ambient radiation from the side. Consider whether 9.2.5 Ambient temperature
compensating applies to the measurement application.
10 Settings via interface / software
The operating and analyzing software InfraWin is included in delivery of the pyrometer. With this software all
pyrometer functions also can be used on the PC. Also temperature indication, analyzing of the measurement
and data logging can be done with this software.
Note: If the settings directly at the pyrometer should be used the pyrometer must be
switched into online mode (ONL, see 8.2).
This section gives an overview about the functions of the software. Additionally there is a description of the
individual icons in the program’s help menu. Click on the F1 button after InfraWin has been loaded or click
on the ? in the menu bar.
The following descriptions require minimum the program version 4.0. The latest version is available for free
as download from the homepage www.lumasenseinc.com.
10.1
Connecting the pyrometer to a PC
The program InfraWin can operate up to two devices. For two devices using the RS232 interface, two PC
interfaces must be used. Two devices using RS485 may be operated simultaneously by the same interface,
if two different addresses have been properly entered (see 9.2.4 Address).
10.2
Installation
For installation select the setup program “setup.exe“ from the InfraWin-CD or from the downloaded and un-
packed zip file from the internet and follow the installation instructions.
