7 Calibration
Sensitivity and zero point of the connected sensors must be adjusted as necessary in accordance
with the operating instructions for the types of sensors connected to the system.
Sensors which are no longer able to generate the minimum signals must be replaced.
Two calibration modes are available:
• In one mode two persons are required to perform calibrations. Person 1 operating the
SUPREMATouch and Person 2 supplying the sensors with gas. It is necessary for them to
communicate during the calibration.
• In the other mode only one person is required. This person starts the calibration, goes to the
sensors to apply gas and finally finishing the calibration back at the SUPREMATouch.
NOTICE
Observe and follow all regulations and rules regarding use of communication devices in the area
where the SUPREMATouch is installed.
7.1 Calibration Submenu
Calibration parameters for the individual inputs can be set in the calibration menu. From that point
on the calibration is controlled by the SUPREMATouch.
The window is divided into two subwindows:
•
Start calibration
• End calibration
If an input is selected that is not already in calibration mode, the Start calibration window appears.
If an input is selected that is already in calibration mode, the End calibration window appears.
The fields Measuring Point and Tag fields are available in both windows.

The preadjustment is applied immediately and cannot be cancelled or discarded.
