   The precision bubble level and the triangular gauge block are expensive, high-precision components that must be kept clean. Also, keep all measuring surfaces clean. 精密气泡水平仪和三角形量块是昂贵的高精度部件，必须保持清洁。此外，保持所有测量表面清洁。 Do not place the bubble level and triangular gauge block on the floor. Place them on a clean cloth or other protective surface when not in use. 请勿将气泡水平仪和三角量块放在地板上。不使用时，将它们放在干净的布或其他保护表面上。

   Check the precision bubble level for calibration before use. 使用前检查精密气泡水平仪进行校准。 Verify that the level gives the same indication when the level is rotated 180 degrees on the long axis. If the level is not the same when rotated, then the level should be removed from use until it is recalibrated. 验证当水平仪在长轴上旋转 180 度时，水平仪是否给出相同的指示。如果旋转时液位不同，则应停止使用该液位，直到重新校准。

   i

   The calibration of the precision bubble levels will need to be verified before the leveling process is complete. In order to verify the calibration of the levels, a surface which is level enough to float the bubble on the precision level will be needed. If possible, verify the calibration now by first placing one level on one of the triangular gauge block and note the position of the bubble. Rotate the level 180˚ and note the position of the bubble. The position should be the same in both cases. If the bubble is at a different position after the rotation, the level is out of calibration. Repeat the verification for each level in use at this time. 在矫平过程完成之前，需要验证精密气泡水平仪的校准。为了验证水平仪的校准，需要一个足够水平的表面，以使气泡漂浮在精密水平仪上。如果可能，现在验证校准，首先将一个水平仪放在其中一个三角形量规块上，并记下气泡的位置。将水平仪旋转 180° 并注意气泡的位置。在这两种情况下，位置应相同。如果气泡在旋转后位于不同的位置，则水平超出校准范围。对此时使用的每个级别重复验证。

   i	If level is out-of-calibration refer to Appendix D for calibration procedure before continuing. 如果液位超出校准范围，请在继续之前参考附录 D 了解校准程序。

6. Place two precision bubble levels between the dots on the triangular gauge block.

3. Determine the height level of each of the rectangular gauge blocks. The highest elevation is the side with the lowest reading.
   确定每个矩形量块的高度标高。最高高程是读数最低的一侧。

   i

   For example, if the reading on the left gauge block is 1.400 and the reading on the right gauge block is 1.200, then the right gauge block is 0.200 higher than the left. Therefore, the left jackscrews should be adjusted to raise the gauge block by 0.200. The difference between each block should be no more than 0.003. 例如，如果左侧量块上的读数为 1.400，右侧量块上的读数为 1.200，则右侧量块比左侧量块高 0.200。因此，应调整左顶丝杠，将量块升高 0.200。每个区块之间的差值应不超过 0.003。

   i	For consistency, keep the bubble levels in the same orientation throughout the following process. 为了保持一致性，在接下来的过程中，请保持气泡水平仪处于相同的方向。

4. Raise and re-level the low side of the PET gantry jackscrews so that they match in elevation to the high side.
   升高并重新调平 PET 龙门式顶丝杠的低侧，使其在高度上与高侧匹配。

5. Verify the height by moving the pinpoint receiver from side to side, and adjust until the height matches. When this condition is met, you can level the remainder of the jackscrews in each row relative to the starting jackscrew.
   通过将精确接收器从一侧移动到另一侧来验证高度，并进行调整直到高度匹配。满足此条件时，您可以相对于起始顶丝杠调平每排中的其余顶丝杠。

6. Position the lock-down disc of each jackscrew against the floor after adjustment.
   调整后，将每个顶丝的锁定盘靠在地板上。
