: IR source voltage setting
The jumper JP2 is for setting voltages of the IR sources. All available sources in an IR cell are
connected in series. Normally the voltage of each source is 1.75 VDC. The total voltage of all
available cells can be measured on test point TP7 against TP1=GND.
Caution: In case of adjusting resp. changing the IR source voltage, the base lines take a few
minutes to stabilize at a new level.
In case of problems with adjusting the base line see chapters “Infrared cell adjustments” and
“Infrared power supply”.
