Offset adjustment VR1
The Volume for output analogue voltage adjustment
Adjustable range : about ±1.0V Default value
：
0.05V
－
Applied voltage to photo detector adjustment VR3
Adjusts the applied voltage to the photo detector (Photo Multiplier Tube)
Sensitivity of detector can be changed.
Adjustable range : about 0V - 1.0V
Stronger voltage makes sensitivity higher.
※
When you keep on setting high sensitivity, the life of detector shorten. Please set the voltage
from 0.3V to 0.5V.
