For the emissivity, the pyrometer has a quick adjustment function� In the
process value display the value can directly be entered by using the ▲or
▼ button without changing to the menu. When simultaneously pressing
the MODE key, the display shows the current measuring temperature
while the emissivity coefficient continues to be adjusted in the backg-
round� This is an easy way to determine the emissivity when the object
temperature is known� The modified values are directly adopted�
Change the emissivity only when the measuring mode “one-colour” is
active�

5.17 Transmission factor (one-colour mode)
Besides the emissivity correction, a pyrometer must be adjusted for the transmis-
sion properties of any supplementary lens and/or protective window screwed onto
the pyrometer� Set the pyrometer for the specific transmission factor (a percentage
value) which is indicated either in the product’s data sheet or on the lens itself�
If you are not using any auxiliary lens or protective window, set the parameter to
100�0�

5.18 IO-Link
This device has an IO-Link communication interface, which requires an IO-Link-
capable module (IO-Link master) for operation� The IO-Link interface allows direct
access to process and diagnostic data and offers the possibility to parameterize
the device during operation�
The IODDs required for configuring the IO-Link device as well as detailed informa-
tion on process data set-up, diagnostic functions and parameter addresses
are available in the download area at www�keller-msr�de/pyrometer�
A 3-wire cable port Class A (Type A) must be used for IO-Link operation�
