Turn the resin cap
90° counterclockwise
to release the lock.
After powering on, wait at least 15 minutes for warm-up (30
minutes recommended) in an energizing state before performing
an adjustment.
The factory-default movable area of the zero trimmer is
approximately 120 degrees to the left and right (approximately 240
degrees minimum to maximum). When turning the zero trimmer,
use the following cross slot driver without applying excessive
torque (within 5 m N·m).
Material: resin or ceramic
Size of cross slot driver (bit No. 0): shaft length of 10 mm or more,
shaft diameter of 2.8 mm or less
Recommended product: No. 9000 by Bessel ⊕ 0 × 30
For adjustment, use a traceable measuring instrument.
Do not perform adjustments with moisture adhering to the product.
Moisture or other foreign matter entering the case may cause
malfunction.
Never cause short-circuits with a driver (use a resin or ceramic
driver).
Pulling the plastic cap hard will impair its simple fall-prevention
function. Be careful not to pull it too much (should be 1.1 N or less).
* Damage to the fall-prevention function will not affect the function of the
product itself as long as the plastic cap and gasket seal are intact. In this
case, cut the fall-prevention portion of the product before use.
