10.3 Pyrometer Calibration

To obtain the measurement accuracy, we recommend to re-calibrate the pyrometer periodically (annually) with
the help of calibration sources and optionally adjust at Process Sensors Corporation.
▪ Fiber-optic pyrometers must always be calibrated together with the associated optics and the optical fiber
cable.
▪ A recalibration is also necessary if (for fiber optic pyrometers) the optics OL12 is replaced by OL25 or vice
versa and / or a new fiber optic cable should be used.

10.4 Trouble-Shooting

A device defect is indicated by a red power status LED (right LED 4). This may be a data transmission error or
a firmware problem. If the interface is not affected, the error can be read out via the
nal box, see 7.5) and discussed with our service team.
To further limit the possibilities, a service file can be created via the software SensorTools (see under
Device Settings and Configuration →
for further support.

Communication via Serial Interface / Interface Commands

Interface commands are used to communicate directly with a Process Sensors pyrometer. Commands can be
used to write an own access control or can be entered in the terminal field of the software SensorTools (see
7.5 Communication / Options) or entered via a terminal software.
▪ Data is exchanged in ASCII format with the following transmission parameters:
8 bit, 1 stop bit, even parity (8,1,e)
▪ Command sequence to write parameters:
2-digit device address → command → parameter → <CR> (Carriage Return)
▪ Command sequence to read out the current set parameters:
2-digit device address → command → <CR> (Carriage Return)
|INFO|
▪ Device address (also see in 6.3.14): In factory setting the device address is 00 but can be changed directly
at the pyrometer (under INTERFACE> → ADD).
In the Terminal field
▪ Parameters are encoded in hexadecimal unless specified otherwise.
▪ When writing with valid parameters, the response will be ok + <CR>
▪ When writing with invalid parameters, the response will be no + <CR>
▪ Deviating reading commands are in parentheses at the respective commands.
Example:
Input in terminal programs
with device address 00
00ar1<CR> sets the 2nd analog output to 4-20 mA
00ar reads out how the analog output is set
