Maintenance
CAUTION, switch off supply voltage.
Before beginning any maintenance, switch off power supply or pull connector on the Pola-
ris to prevent injury by accidentally activated laser targeting light!
7.1
Cleaning
Clean the lens with a soft cloth and a little alcohol or acetone. Use only high-purity acetone to avoid res-
idues.
The objective lens is not
to clean with solvents that contain acid
immerse in water or other liquids to clean
7.2
Calibration
To obtain the measurement accuracy, we recommend to re-calibrate the Polaris at Sensortherm period-
ically (annually) with the help of calibration sources.

Communication via Serial Interface / Interface Commands
Interface commands are used to communicate directly with a Sensortherm device. Commands can be
used to write an own access control or can be entered in the terminal field of the software
SensorTools
(
in the main window in the tab “miscellaneous”) 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 structure:
For successful communication the following sequence of a command is used:
Device Address - Command - Parameter
Device address:
all interface commands are starting with the 2-digit device address (exception: in
the terminal field of the
SensorTools
software no address is required). In factory setting the device
address is 00 but can be change per command.
Device addresses from 00 to 99 are valid but 98 and 99 are with special functions. The global ad-
dress 99 can be used to communicate with every device, independent of the set address. This allows
communication with devices which have unknown addresses. The address 98 is a group address
used for RS485 devices. Devices do not answer with this address, useful to change parameters of all
connected devices at the same time.
Command:
command have to be completed with a carriage return <CR> (decimal 13).
Parameter
(Unless otherwise specified, coded hexadecimal)
:
without parameter
the command reads out the current set value. The answer at request commands
is the set value of the device corresponding to the possible settings described in the table. Answers
are normally finished with a <CR>. Deviating read commands are in parentheses in the respective
write commands.
With parameter
the parameter will be set into the device. A setting command answers with
ok+<CR>, this means the command is accepted.
