Configuring the E102:
The Auto-Off Delay and Output Polarity can be set using the table below:
The E102 can be used to connect a User electrode to the QT102 (using EXT and GND pads: The
value of Cs may require changing. Large pads either side of Cs are available for fitting leaded
capacitors in parallel). The E102 can also connect to a User output (using OUT and GND pads).
The Auto-Off Delay can be extended or the QT102 output can be switched off immediately by pulsing
the voltage on the delay multiplier resistor RM through J5.
