公路连续式八轮平整度仪使用注意事项
★运输、转向、停放及其他非测量状态必须将测量轮悬起,避免不必要的磨损与冲撞;
★测试速度必须保持在12km/h以内。路面情况不好,测速应相应减慢,以免机架颠簸太大影响测量精度。远距离运输应将测试仪器装在运输车厢内,短距离运输,可直接用机动车牵引,但速度应小于25km/h为宜,以避免速度过大,震动大损坏机件;
★仪器箱交货时已经调试好,用户不得打开电器箱面板,更不能随便更换原件、焊线,以免损坏仪器,否则公司不予维修,如线路故障请与本公司联系。

Road continuous eight-wheel flatness meter use precautions
★ Transportation, steering, parking and other non-measurement conditions must suspend the measuring wheel to avoid unnecessary wear and impact;
★ The test speed must be kept within 12km/h. If the road surface is not good, the speed should be slowed down accordingly, so as not to affect the measurement accuracy. Long-distance transportation should be installed in the transport compartment, short-distance transportation, can be directly used to pull the vehicle, but the speed should be less than 25km / h is appropriate to avoid excessive speed, vibration damage to the machine;
★The instrument box has been debugged when it is delivered. The user should not open the panel of the electrical box, and can not replace the original parts and welding wire, so as not to damage the instrument. Otherwise, the company will not repair it. If the line is faulty, please contact the company.

 

公路连续式八轮平整度仪维护及保养:

★仪器采用内部充电电池供电,充满后可连续使用20小时以上(若关掉背景光则可延长使用时间);
★每次使用之前,应充满电(一般充电八个小时左右);
★仪器在监控状态时,若电池不足会显示“请充电!”,此时应尽快充电,以免在工作中因电不够而中断。
★仪器长期不使用,则每2-3个月应充电一次,确保电池不损坏。
★平整度仪是精密电子仪器,如传感器、计算机、打印机等部件,切勿淋雨、受潮,不用时要妥善保管,定期通电,以免损坏;
★机架上轴承和运动部分要经常加油润滑,防止生锈磨损。使用前后应检查连接螺栓是否紧固。在长途运输后尤其要认真检查;
★测量轮的磨损会影响测量的精度,因此行驶足够里程后,要检查其直径及时更换。另外测量轮的标准直径为159.2mm;
★仪器电缆线在使用时,因使用不当容易发生断路现象,此时可用万用表检查连线的通断,电缆连线的连线位置图见附页,排除故障时,断线一定要用熔电焊接牢靠,各线间不要接触,以免影响仪器的使用。
★使用前与使用后位移传感器测杆须擦拭干净。

Maintenance and maintenance of highway continuous eight-round flatness meter:
★The instrument is powered by internal rechargeable battery. It can be used continuously for more than 20 hours after being fully charged (if the background light is turned off, the use time can be extended);
★Before each use, it should be fully charged (usually charged for about eight hours);
★When the instrument is in the monitoring state, if the battery is insufficient, it will display “Please charge!”, please charge it as soon as possible to avoid interruption due to insufficient power during work.
★ If the instrument is not used for a long time, it should be charged once every 2-3 months to ensure that the battery is not damaged.
★The flatness meter is a precision electronic instrument, such as sensors, computers, printers, etc. Do not expose to rain or moisture. When not in use, keep it in a safe place and energize it regularly to avoid damage;
★ The bearings and moving parts of the frame should be lubricated frequently to prevent rust and wear. Check that the connecting bolts are tight before and after use. Especially after long-distance transportation, it is necessary to check carefully;
★The wear of the measuring wheel will affect the accuracy of the measurement. Therefore, after driving enough mileage, check the diameter and replace it in time. In addition, the standard diameter of the measuring wheel is 159.2 mm;
★When the instrument cable is in use, it is easy to break due to improper use. At this time, the multimeter can be used to check the connection of the connection. The connection position of the cable connection is shown in the attached page. When troubleshooting, the disconnection must be melted. The welding is firm and the wires should not be touched to avoid affecting the use of the instrument.
★ Before use and after use, the displacement sensor rod should be wiped clean.
