DSZ3型水准仪的补偿器在同类产品中处于领先地位，其工作状态的正常与否对水准仪的测量精度有很大影响，因此，水准仪补偿器的校正是测量人员和维修人员应熟练掌握的技能。
   对DSZ3水准仪补偿器的检验：首先轻推位于后盖左下方的按钮，看补偿器是否卡死，如能正常抢劫，则证明补偿器没有卡死；然后用螺丝刀将后盖的三颗螺钉卸下，背后盖轻轻取下。对DSZ3型水准仪补偿器的校正可分为四个部分：
1. i角误差的校正
将仪器放于校正台上，调整圆水泡居中并将仪器整平，将仪器望远镜对准平行光管中心，看仪器十字丝与平行光管的十字丝是否重合，如不重合，则证明有I角误差，需要校正；如果两十字丝间相差超过20″，则可通过调整补偿器正面左方的螺钉来校正误差；若两个十字丝相差不足20″，则调整补偿器正面上方的螺钉即可。
2. 补偿精度（补偿范围）的校正
将仪器放于校正台上，调整圆水泡居中并将仪器整平，在仪器补偿范围内，倾斜仪器（即使仪器前高后低或后高前低），此时若仪器分划板十字丝高于或低于标准目标十字丝，则可通过调整补偿器正下方两悬垂的长螺钉来校正，直至调整到允许范围之内。
3. 补偿器零位的校正
将仪器放于校正台上，调整圆水泡居中并将仪器整平，若补偿器的补偿范围是30″，但当其误差为10″时，补偿器已不能正常工作，则证明该补偿器需进行零位校正，在补偿器正下方有一排四个的螺钉，中间有封漆的两个不可动，左右两边的两个螺钉可以调整补偿器的零位。
4. 补偿器交叉误差的校正
将仪器放于校正台上，调整圆水泡居中并将仪器整平，则在仪器补偿范围内倾斜仪器（即使仪器左高右低或右高左低），此时若仪器分划板十字丝高于或低于目标十字丝，则证明仪器有交叉误差，可通过调整补偿器左右两边偏上处的两颗小螺钉来校正，直至调整到允许范围之内
 

Type of compensator Level DSZ3 similar products in a leading position in its normal working state or not on the water level has great influence on measurement accuracy, therefore, water level compensator correction is to measure staff and maintenance personnel should be familiar with skills.
    Level Compensator for DSZ3 test: First Light push button located on the bottom left back cover to see whether the card compensator death, if a normal robbery, then the evidence is not stuck compensator; then use the screwdriver to the rear cover of the three screw unloading Next, gently remove the back cover. Right DSZ3 type Level compensator calibration can be divided into four parts:
1. I angle error correction
Instrument calibration will be put in the stage, adjusting the circular bubble center and leveling equipment, will instrument the telescope alignment collimator center to see if instrument cross wire and parallel fluorescent tubes whether the coincidence of the cross wire, if not coincide, then prove that I angle error, need correction; if the difference between the two cross-wire for more than 20 ", can be compensated by adjusting the front left of the screw device to correct the error; if the two cross-wire difference of less than 20", then adjust the compensator screw the top of the front be.
2. Compensation precision (compensated range) correction
Instrument calibration will be put in the stage, adjusting the circular bubble center and leveling instrument, the instrument within the scope of compensation, tilt apparatus (even if the equipment from high to low before or after the high-low) at this time if the device reticle cross Sgro at or below the standard target cross-wire, you can compensate by adjusting the device is hanging below the two long screws to correct until the adjustment to the permitted range.
3. Compensator zero correction
Instrument calibration will be put in the stage, adjusting the circular bubble center and leveling instrument, if the compensator for compensation is 30 ", but the error is 10", the compensator is no longer working properly, then the need to prove that the compensator correction to zero in the compensator is below a row of four of the screws, the middle two letters paint can not be touched, left and right sides of the two screws can be adjusted compensator zero.
4. Compensator cross-error correction
Instrument calibration will be put in the stage, adjusting the center circle and equipment leveling bubble, then tilt the instrument within the scope of compensation equipment (even if the device left or right of high right low left high-low) at this time if the device reticle cross Sgro on or below the target cross-wire, then prove that there is cross-instrument errors can be compensated by adjusting the device on the side at left and right sides of the two small screws to correct until the adjustment to the permitted range
