About Sensitivity Sensitivity (mm/m) represents either height or angle of gradient which is required to move main bubble a scale. For example, you will know there is 0.02mm height difference 1m away from where you measure, when the main bubble moves a scale. NOTE 0.02mm/m is 4 seconds = 0.0011 ˚ 0.05mm/m is 10 seconds = 0.00277 ˚ 0.1mm/m is 20 seconds = 0.0055 ˚
• Grade B · are manufactured and inspeected under the JIS B 7510 standard. • Grade B has · less than 3µm accuracy in flatness between base and side. (0.02 mm/m type) · Squareness between base and both side is 0.015 mm/m.
