iLevel series high-precision electronic level meter are fully independent research and development of products. It has a precision of 1μm/m, built-in temperature compensation and flexible button operation. Unique sensor calibration procedures can be switched relative and absolute measurement mode. Wireless matching is connected with the mobile terminal, which is truly applied in the precision measuring instruments of the Internet of things.
Put the meter on a nearly horizontal platform, record data (D1) after reading stable. Then rotate the meter 180 degree along the arrow, record data (D2) after reading stable. If value D1 equals D2 (with negative), the meter’s zero output is accurate, otherwise do absolute zero recalibration as indicated.
Absolute zero recalibration
Put the meter on a nearly horizontal platform, press “Z” after reading stable. When arrow displayed on screen, rotate the meter 180 degree along the arrow, press “Z” again after reading stable, then arrow disappeared. The absolute zero recalibration finished.
Relative zero recalibration
Put the meter on the target reference platform, press “Z” after reading stable. When arrow displayed on screen, press “Z” again after reading stable, then arrow displayed on screen. The relative zero recalibration finished. Not to move the meter during this course.
