The sensor is the narrow horizontal stripe in the lower area of the finger guide. The front knuckle of the finger must be swiped completely over the sensor for best results. The sensor must not be exposed to any mechanical stress other than operation with the finger.
Do not scratch the sensor with your fingernail. Never clean the sensor with the rough side of a sponge or with aggressive cleaning agents. A damaged sensor must be replaced.
Experience shows that fingers are most suitable in the following order: first middle finger, second index finger, third ring finger. The thumb and little finger should not be used. Everyone has better and less suitable fingers. The writing hand is advantageous because you have more feeling in this hand (right/left-handed people). Please choose a clean finger without injuries and abrasions. A groove structure that is genetically determined or too shallow due to wear and tear cannot be detected by the sensor. A beautiful and clearly visible grooved structure makes it easier to identify. For children, the index finger, or whatever finger the child uses intuitively, works best. Use the fingers that are most comfortable to use and quickest to recognize.
For comfortable two-handed operation and as a precautionary measure in the event of injuries, one finger of each hand should be taught in. In the case of fingers that are not so easy to scan, such as small children, older people or craftsmen, the same finger should be taught in on several memory locations. 99 finger storage locations are available with ekey home/ekey multi. In principle, it is better to save one finger several times than several fingers each once. This increases the chance of detection and the system works better in border areas (dry fingers, skin cream or sweat after sport) or with unfavorable operation.
With the 1-relay variant, you simply use the same user memory location, e.g. B. F1-F5 for the first finger and F6-F10 for the second finger. You have used up 5 reference scans each and therefore a total of 10 storage locations.
Children’s fingers: Basically, children’s fingers work from about school age. However, it may be possible to train younger children using the multiple storage described above. The prerequisite for correct operation is the specified mounting height for IN, AP and UP. If, when you swipe your finger over the sensor, the LED immediately lights up red without flashing yellow beforehand, the finger was not swiped correctly over the sensor, or you waited too long. As soon as the finger is placed on the sensor, it must be pulled down immediately. The software interrupts the scanning process and signals this by the LED briefly flashing red.
Example person 1:
- Memory 1, F3 for the left middle finger
- Memory 1, F8 for the right middle finger
A list of the recorded fingers is useful for control units without a multi-line display.
