Installation

  • Install a proper camera lens onto the CS mount of the camera

  • Connect the VGA OUT terminal to a VGA display using a VGA cable

  • Plug the 5V DC AC adaptor into the 5V DC IN socket of the camera




Menu Operation

  • Press MENU once, main menu pops up; press MENU again, main menu closes.

  • Press ↑/↓to highlight menu, then press → to select menu.

  • If there is a submenu, press ↑/↓ to highlight submenu, then press ←/→ to change value of the selected submenu.

  • Select Exit to return to main menu.   



Method of Measurement 

  • Place the sample under test on the specimen stage, while keeping the calibration of the system unchanged.

  • Through keys SEL,↑,↓,← and → to move lines to measure distance between a pair of lines in H or V direction.

  • Screen freeze: press POWER for one second, screen will freeze for more stable measurements.

  • Press POWER one second again to release freeze function.

  • Press POWER about 3 seconds to turn off power of the camera.
