Circuit system
Circuit system consists of power adaptor, different analog voltage stabilizing circuits, the three-way
motor drive circuit, preamplifier, and computer-controlled system power.
Power transformer provides all AC power that the equipment needs.
The voltage stabilizing circuit includes 12V/20W tungsten lamp with constant voltage source, ±15V vol-
tage stabilizing working power, +12V DC fan power supply, 12V DC power supply for stepper motor, 5V
power supply of large current with stable voltage for computer work, and constant current for deuterium
lamp.
This local front-end system has a three-way circuit including photoelectric current amplification, pro-
gram controlled gain amplifier and (V/ F) conversion. Photoelectric detection device adopts high quality
silicon battery, which has long service life, shows good endurance and is not easily moistened.
Computer system
The computer system is equipped with high performance ARM processor, which is stable and reliable.
It communicates with external computer system via USB.
It is also equipped with print port. The display is large color LCD touch screen.
