  • 1. Insert AC/DC adapter into connector "+12V DC" (Attention on voltage polarity).
  • 2. If necessary connect "Connector for synchronizing pulses" with selective amplifier of the detector signal (Attention on voltage polarity).
  • 3. Insert IBSG LED into connector "LED" (Attention on voltage polarity - + to the red point on the LED package).
  • 4. Select operating mode - "QCW" or "Pulse" (switch "Operating mode"). Green LED will indicate selected mode.
  • 5. Select frequency - "0.5 kHz, 2 kHz, 8 kHz or 16 kHz" (switch "Freq"). Green LED will indicate selected mode
  • 6. If you are going to work in pulse mode, select pulse duration - (one of 10 positions on switch "Pulse duration").
  • 7. Set pozition "0" on Switch "Current"
  • 8. Switch On Driver (switch On/Off). Green LED "Working" will indicate that current is flowing. If after switching on current is not flowing red LED "Break" will indicate break of the circuit. That situation can take place if testing Infrared LED is damaged.
  • 9. Select drive current that you need beginning switching from "0". Please, be sure that drive current don't expire maximum value fo
