5.3 Easy Trim Function (ETF)
This function allows adjusting the reader to its environmental conditions.
The ETF is a semiautomatic function for trimming the reader to its best performance.
The ETF starts if switch
S1
is pressed.
In this mode only one of the three LEDs is blinking. The individual meaning of each LED is:
Red LED:
The rotatable switch
(S5)
must be turned to the right
Yellow LED:
The rotatable switch
(S5)
must be turned to the left
Green LED:
The setting of the rotatable switch
(S5)
matched the best performance.
It could be possible that there are two settings of the switch that match the best performance.
If there are two possible positions of the rotatable switch
(S5)
, it is better to choose the position
before the yellow LED is blinking.
The ETF ends after switch
S1
is pressed again. It also ends after 6 minutes.
If the reader should be mounted directly on metal ground (distance to metal is lower than
2 cm) the switch
S7
must be actuated before the rotatable switch is turned.
