Fixed voltage ( or Auto voltage selectable ) power supply circuit is used in this unit.  If Main Fuse (F601) is blown, check to see that all components in the power supply circuit are not defective before you connect the AC plug to the AC power supply.  Otherwise it may cause some components in the power supply circuit to fail. BECAUSE A HOT CHASSIS GROUND IS PRESENT IN THE POWER SUPPLY CIRCUIT, AN ISOLATION TRANSFORMER MUST BE USED.  ALSO, IN ORDER TO HAVE THE ABILITY TO INCREASE THE INPUT SLOWLY, WHEN TROUBLESHOOTING THIS TYPE POWER SUPPLY CIRCUIT, A VARIABLE ISOLATION TRANSFORMER IS REQUIRED.

The AVR Stick is a simple data logging device that instantiates itself as an HID keyboard and reports the voltages, along with a ‘timestamp,’ from two pins on an ATtiny85. The device uses open source firmware availabe from Objective Development (http://www.obdev.at/vusb/) called V-USB to implement the USB 1.1 standard. The code that runs the application was based on the EasyLogger example application from Objective development.

PRECAUTIONS FOR CHECKING BEAM EMISSION The laser beam of this unit is focused on the reflecting surface of the objective lens in the optical system block.  Therefore, keep your eyes at least 12 inches (30 cm) away from the objective lens when the laser diode is ON.  (Operation Check Method for Laser Diode and Focus Search Function.) When the POWER switch is turned ON after the chucking plate is removed, observe the objective lens and confirm that the following operations are performed properly. (The optical system should be at the lead-in area position when it is checked at this time.) (1) The laser should be at the innermost position after the chucking plate is removed. (2) The diffused light of the laser beam can be seen when the POWER switch is turned ON. (3) Vertical (up and down) movement of the objective lens (2 or 3 times) will take place.
