10.3 Pyrometer Calibration
To obtain the measurement accuracy, we recommend to re-calibrate the pyrometer periodically (annual-
ly) with the help of calibration sources and optionally adjust at Sensortherm.
 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 malfunction is indicated by a red power status LED (right LED 4). This may be a data trans-
mission error or a firmware problem. If the interface is not affected, the error can be read out via the fs
command (in the terminal box, see 7.4). For interpretation of the answer please contact us so that we
can find a solution of the problem.
To further limit the possibilities, a service file can be created via the software SensorTools (see under
7.2.3 Device Settings and Configuration  Service Functions) that can be sent to Sensortherm for
further support.
11 Communication via Serial Interface / Interface Commands
Interface commands are used to communicate directly with a Sensortherm pyrometer. Commands can
be used to write an own access control or can be entered in the terminal field of the software Sensor-
Tools (see 7.4 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)
 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 of the SensorTools software no address is required.
 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>
Example:
Input in terminal programs
with device address 00
Input in terminal program of SensorTools
without device address
00ar1<CR> sets the 2nd analog output to 4-20 mA
00ar reads out how the analog output is set
ar1<CR> sets the 2nd analog output to 4-20 mA
ar reads out how the analog output is set
Note: The following commands are valid with the newest firmware version.
