2) 通过\按钮,自动选择正负极。Select automatic positive-negative by means of the

\

3) 按下开始按钮，数字屏幕将会显示平坦金属板电极有约1500伏且布满LED杆。Press

the \approximately 1500 V shown by the digital display and full scale of the LED bar.

4) 三角形符号上的箭头闪动，显示出1000至100伏的静电下降时间。The arrow in the

triangle symbol will flash, then the static decay time from 1000 to 100 V will be measured.

5) 记录测量结果并反馈到相关部门，以便针对不合格测量结果采取适当的措施Record

the measurements and feed back to concern department to take proper actions regarding non-conforming measurements.

电离空气会压制平坦金属板电极上的电荷，然后测量出静电下降时间和偏移电压。Note: The ionized air will neutralize the charge on the flat plate electrode and the decay time and

offset voltage will be measured. 下降时间Decay Time = / < 5 seconds 平衡电压Balance Voltage = / < 5 volts

5. 工作台、货架、地板上的垫子检查Checking of MATS on Tables/Racks/Floor

1) 利用电阻检查仪检查表面特征，特别是直接放置元件的静电耗散垫子。如图5a所示：

Using the resistivity checker, check the characteristics of the surfaces especially the static dissipative MATS where units are being laid directly. See figure 5a.

（静态耗散规格：Specification for static dissipative : 106to109 ; 导体规格for conductive:

= or < 105 ）

2) 记录测量结果，针对不合格测量结果采取适当的措施Record the measurements and

take proper actions regarding non-conforming measurements.

3) 同时，记录传导表面的特性和测量结果，针对不一致读数采取适当的措施。如图5b

所示：Also, measure the characteristic of the conductive surface then record the measurements and take proper actions regarding non-conforming readings. See figure 5b.

4) 点对点，点对地检查耗散垫子和传导垫子的电阻，如图5c所示：记录测量结果，针

对不一致的测量结果采取适当的措施。Check the resistance of Dissipative and Conductive Mat from Point-to-Point and Point-to-Ground. See figure 5c. Then, record the measurements and take proper actions regarding non-conforming measurements.

备注：地板上的垫子只在必需时检查，特别是带有Class 100和 Class 1000类型的无尘室Note:MATS on floors are being check only when necessary, especially for Clean Room

with Class 100 and Class 1000 types.

6. 设备/机器。Equipment / Machines .

1) 利用万用表（或其它同类品），检查机械设备和地线设施之间的地线接点的连续性。

Using a multimeter (or any equivalent), check the continuities of the connections of the grounding from the machine/equipment body to the grounding facilities.

2) 将万用表的一个测试探针接触到机器/设备，另一个测试探针接触到地线系统设施，

读取万用表上的数据可测出其连续性。Point 1 test probe of multimeter to the body of the equipment/machine and point the other test probe to the machine grounding system, then observe the continuity reading of the multimeter.

3) 如有必要，维修连接线路。Repair connections, if necessary. 7. 烙铁检查Checking of Soldering Iron

1) 用万用表或其它同类器械测量烙铁的遗漏电压和电阻。Measure the leak voltage and

resistance of soldering iron using a multimeter or any equivalent.

2) 在烙铁末端放置一个探针，另一个探针放在接地设备上。Set 1 probe at tip of the

soldering iron and the other probe to the equipment ground.

3) 记录测量结果并反馈到相关部门，以便针对不合格测量结果采取适当的措施Record

the measurements and feed back to concern department to take proper actions regarding non-conforming measurements.

备注：开启烙铁后进行测量。对每个生产线上用到的至少3个烙铁进行漏电压和电阻测

试

Note: Perform the measurement while the soldering iron is ON. Conduct leak voltage and

resistance check to at least 3 soldering iron used per line.

8. Personnel Ground on Tables and Racks

1) 利用万用测试仪上的欧姆表（或其它的仪器），检查连接到接地系统的电阻器。Using

the Ohmeter of the multitester (or any equivalent), check the presence of the resistor connected to the grounding system.

2) 将万用表的一个测试探针放在接地线系统上，另一个探针直接连在地线（电线）上。

Position 1 test probe of the multimeter to the personnel grounding system and the other test probe directly to the earth ground or electrical ground.

3) 记录测量结果，针对不合格的测量结果采取适当的措施。Record the measurements and

take proper actions regarding non-conforming measurements.

4) 对于使用双重保护装置的生产线来说，当检查双重保护装置时，必须戴上良好的接

地手环，然后连接在双重保护装置上，绿色发光二极管必须发亮，然后拆开双重保护装置，会听到蜂鸣器显示发生错误，红色二极发光管会亮.For lines using twin guard, checking of twin guard must be done by using known good groundstrap wear groundstrap
