CHAPTER 1 INTRODUCTION
Thank you for purchasing the Digital Air Micrometer (DAG2000). This manual is explained such that even first time users of the Air Micrometer will be able to use the abundant functions of this product efficiently. Please read the manual thoroughly to use this product well.
1.1 Outline
• This product is a measurement device that detects the air pressure changes based on the dimensions of the measurement subject through sensors, and makes judgments based on digital dimension indicators and lamps.
• This product is a comparison measurement device.
Measure the master for reference and then do measurements. With regular master calibrations, good precision measurements are possible.
• This product judges independently if the measurement value is OK or NG.
Judgment result display can be quickly distinguished through the indicator color of the main display and judgment LED. Also, regular master calibrations can be done through the panel key.
1.2 Merits
