UNRESTRICTED
1. All temperatures are in tenths of degrees C
2. Writing to unlisted registers could cause malfunction
3. All write and mask operations are saved to non-volatile memory
4. For further information please refer to http://www.omega.com
5. Use address 255 to communicate with any connected sensor. Use address 0 to broadcast to all connected sensors (no response expected)
OPERATION
Once the sensor is in position and the appropriate power, air and cable connections are secure, the
system is ready for continuous operation by completing the following simple steps.
For OS-MINI and OS-MINI22:
1. Turn on the sensor power supply
2. Turn on the connected instrumentation
3. Read, monitor or log the temperature
For OS-MINIUSB:
1. Turn on the power supply
2. Turn on the Modbus Master
3. Read / monitor the temperature
IMPORTANT
Be aware of the following when using the sensor:
•
If the sensor is exposed to significant changes in ambient temperature (hot to cold, or cold to hot),
allow 20 minutes for the temperature to stabilize before taking or recording measurements.
•
Do not operate the sensor near large electromagnetic fields (e.g. around arc welders or induction
heaters). Electromagnetic interference can cause measurement errors.
•
Wires must be connected only to the appropriate terminals.
VIEWING THROUGH A WINDOW
The OS-Mini is capable of measuring the temperature of a target through a window made of a material
that is transmissive to infrared radiation at 8-14 microns. The emissivity setting of the sensor should be
adjusted to compensate for the presence of the window. Please contact Omega for more information on
using the OS-Mini with a window.
MAINTENANCE
Our customer service representatives are available for application assistance, calibration, repair, and
solutions to specific problems. Contact our Customer Service Department before returning any
equipment. In many cases, problems can be solved over the telephone. If the sensor is not performing as
it should, try to match the symptom below to the problem. If the table does not help, call Omega for
further advice.
