3 Controls and Installation 3.1 Electrical Installation The pyrometers are powered by a voltage of either 24 V DC (15 to 40 V DC) or 24 V AC (12 to 30 V AC), 48 to 62 Hz. Once connected to power, the instrument operations immediately and needs no warm-up time. To switch off the instrument, unplug the connector. To meet the electromagnetic requirements, a shielded connecting cable must be used. The shield of the connecting cable has to be connected only on the pyrometer side to avoid ground loops.

center of the spot, not the exact size. The laser targeting light can be used without affecting the measurement. 3.3 Optics The pyrometers are equipped ex works with a fixed or a focusable optics. The smallest spot size for the fixed optics is shown for the specified measuring distance. With the focusable optics, the smallest possible spot size can always be adjusted for each distance within the optics limits.
Note: The pyrometer can measure objects at any distance but the object has to be bigger than or at least as big as the spot size of the pyrometer in the measuring distance. Calculating the spot sizes on different measuring distances: Spot sizes for other measuring distances can be calculated with the following equations or with the IR calculator of the InfraWin software. Table values: 3.3.
Adjusting the required measuring distance The required measuring distance must be adjusted to achieve the spot size mentioned in the tables above. This can be done between the smallest and the biggest limit value. Note: The measuring object has to be bigger than or at least as big as the spot size of the pyrometer. To release the optics, turn it counterclockwise. Then it can be pushed or pulled to find the correct measuring distance. To fix the optics, turn the optics clockwise.
4 Instrument Settings All instrument settings can be done directly at the instrument. Use the tip of a ball point pen to activate the adjusting keys. This avoids changing parameters by mistake. 4.1 Key panel operation Temperatureor parameter display Indication of limit switches Indication °C or °F Parameter indicator Emissivity Exposure time (t90/s) Clear time of max. value storage (tCL/s) Beginning of sub range (FROM) End of sub range (TO) Analog output 0 or 4 ...
3) ENT: If a parameter is changed with the arrow keys, the new value 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 changes to the temperature indication. 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.
4.4.1 Adjustments The scanning amplitude is adjustable with the scanning angle (0 to 4°) and when the scanning frequency is between 4 and 10 Hz. On the left side of the pyrometer is a cover. Two adjusting potentiometers are under this cover, labeled with an A for amplitude and an F for frequency. For adjustments, a small screw driver is necessary. With the laser targeting light, the adjustments can be controlled.

5 Parameter descriptions / Settings 5.1 Emissivity For a correct measurement, it is necessary to adjust the emissivity. The emissivity is the relationship between the emission of a real object and the emission of a blackbody radiation source (this is an object which absorbs all incoming rays and has an emissivity of 100%) at the same temperature.
5.3 Clear time of the maximum / minimum value storage (tCL) If the maximum value storage is always switched on, the highest last temperature value will be displayed and stored. The minimum value storage saves the lowest measurement taken during a reading. The storage has to be cleared at regular intervals and be replaced with a new and actual value. Settings: 0.00 s 0.01 s . ..
5.4 FROM / TO (beginning and end of sub range) You have the opportunity to choose a sub range (minimum 51 °C) within the basic measuring range of the pyrometer. This sub range corresponds to the analog output. “FROM“ describes the beginning of this measuring range, “TO“ the end of the range. With a sub range, it is possible to fulfill the requirements of the “auto” clear mode of the maximum value storage (see above). 5.
external indicator. If both displays show different readings the external indicator has a wrong temperature range or input current setting. The test function is switched off automatically after 1 minute and the instrument is working in the measuring mode. 5.12 Wait Time 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.
6 Software InfraWin The operating and analyzing InfraWin software is included with delivery of the pyrometer. In addition to allowing you to make parameter adjustments via PC, the InfraWin software also provides temperature indication, data logging, and measurement analysis features. A software description can be found in the program’s help menu. Click on the F1 button after loading InfraWin or click on the ? in the menu bar. The latest version is available for free as download from the homepage www.

7 Maintenance 7.1 Cleaning the front window Since the device does not contain parts that require regular maintenance, the only regular maintenance required is periodic inspection of the front window for build-up of foreign particiles. If allowed to build up, the particles can influence the energy received by the instrument. The window is not water soluable and can be cleaned with standard lens tissue dampened with a commercially available glasses or camera lens cleaning solution.
7.2.2 Focusable optics replacement Only the lens will be replaced for changing the focusable optics. The fixing ring has to be removed with a suitable objective wrench. After removing the old lens, put in the new one with the convex side to the front. Fix the lens with a new O-ring and the new fixing ring. On the inside of this ring is the sticker with the optics data.
8 Troubleshooting Before sending the pyrometer for repair, try to find the error and to solve the problem with the help of the following list. Temperature indication too low Incorrect alignment of the pyrometer to the object New correct alignment to achieve the max.

9 Data format UPP (Universal Pyrometer Protocol) Via interface and suitable communication software or via Test function of the InfraWin software commands can be exchanged directly with the pyrometer. The data exchange occurs in ASCII format with the following transmission parameters: The data format is: 8 data bits, 1 stop bit, even parity (8,1,e). The device responds to the entry of a command with: output (e.g. the measuring value) + CR (Carriage Return, ASCII 13), to pure entry commands with ok + CR.
