Adjustment Of The Reference Sensor Offset (Sensor Module) - Inficom MCT150 Manual De Instrucciones

INFICON
The acceptable variation is given in the data sheet of the specific sensor. The factory set sensor
module, does normally not require any adjustment. Although, a small "drift" can occur due to
environment and the frequency of use.
If the value shown in the display is within the green area
-
If the value shown in the display is within the orange
-
If the value shown in the display is within the red area, the sensor has to be replaced
-
-
If the value in the display increases when entering a plant room e.g., this indicates
that there are substances present that effects the sensor. This value is to be the
reference value for the detectors within this perimeter.

8. Adjustment of the reference sensor offset (Sensor module)

Always start the procedure by checking the due date of the sensor module. (See label on the module).
If due date is passed, the sensor module shall be replaced without delay. Sensors is
a perishable item that is affected by dust, dirt and can be "poisoned" by various
substances such as, aerosols, paint, solvent fumes, glue and similar.
- Before adjustment, the unit should be active in a stable environment for at least one
hour.
At the sensor module there is a potentiometer that is accessible by the hole in the end of the housing
of the instrument:
Carefully adjust by using a small screwdriver. When the offset value passes from the orange area to
the green area, called (normal variation) of the sensor, the task is completed.
The instrument is now ready for use.
