Sensitivity
Sensitivity specifies the degree of acuteness of the scanner’s response to changes in ambient
illumination. The higher the sensitivity, the lower requirement in illumination change to trigger the scanner.
You can select an appropriate degree of sensitivity that fits the ambient environment.
Medium Sensitivity Low Sensitivity
High Sensitivity Enhanced Sensitivity
If the above four options fail to meet your needs, you may program the threshold value of illumination
change.
Illumination changes that reach or surpass the predefined threshold value will cause the scanner to start
a decode session. The lower the threshold value, the greater the sensitivity of the scanner. The default
threshold value is 2.
To learn how to program this parameter, see Appendix 5 .
