EMISSIVITY ADJUSTMENT (-CB MODELS)
The emissivity setting on OS-MINI with MA output models may be adjusted via two rotary
switches inside the electronics box. To adjust the emissivity setting:
Set the left switch to the first digit after the decimal point (0.1).
Set the right switch to the second digit after the decimal point (0.01).
To enter an emissivity setting of 1.00, set both switches to 0.
The minimum emissivity setting is 0.2. If a lower emissivity setting is selected, the sensor will default
to an emissivity setting of 0.95.
For example:

TOUCH SCREEN (MA-R-D and C4-R-D MODELS)
The optional backlit touch screen interface mounted in the lid of the electronics module provides a
large, bright display of the measured temperature, as well as options for full configuration of the
sensor. The graph view shows the history of the measured temperature.
In alarm conditions, the display changes colour to provide an immediate and obvious alarm
indication. Alarm modes and levels can be configured via the touch screen.
