Detector Signal Level
The Detector Signal Level is the level which the sensor is considered to have recovered
from the last gas signal. It decides when the DET_SIGNAL output will come on. this
signal can be used to block the start of a calibration or new test cycle in semi and
fully automatic testers.
IF DET_SIGNAL is high then this means that the sensor has detected hydrogen and
has not yet recovered.
Detector Signal Level can be adjusted in the Service Settings menu . You can increase
Detector Signal Level if you have many small disturbing signals. A high setting of
Detector Signal Level gives better tolerance to “noise” gas signals at the expense of
accuracy. A low setting gives best accuracy but lower tolerance for “noise” gas
signals. The
Detector Signal Level is set as 1 to 100% of the Reject Level . Default is
20%.
NOTICE! Increasing the Detector Signal Level may give poorer accuracy.
