D2002仪表标定说明书
仪表出厂装箱内有三个15芯RS232插头，分别为标定插头、修改地址插头、四角调整插头，用来设置仪表和传感器的有关系数。

仪表正常工作时，均不应插以上3个插头，每次使用以上插头时，应先关机——接上插头——开机——设置系数——拔下插头。

因热插拔插头引起错误现象，应按检查键或关电源重新进行设置。

一、关机——标定插头接上仪表背面的15芯RS232插座上。

（注：出厂装箱内贴
有“标定头“三字的15芯插头，即为标定头）。

二、正确联接传感器，接通电源、仪表进行笔画及声响自检，完毕后进入工作状
态。

三、如在死机（在称重状态下按键无效）时，可关掉电源，插上标定头，在仪表
笔画及声响自检时，按一下[标定]键，即可进入标定状态，以修改因标定错误引起的死机；按[检查]键即可进入查询每一数字传感器的内码查询（具体方法见第四章所述），可了解哪一只传感器或线路故障。

四、标定和参数设置，操作方法如下表：（*：为原设置值，传感器编号以01开
始，如有四个传感器他们的编号依次为01、02、03、04，本仪表标定所示的有关重量值其单位都为Kg。

）
一、标定操作
▲！完成操作后拔下标定插头。

▲！因热插拔插头引起错误现象，应按检查键或关电源重新进行设置。

是测量大容量变压器、互感器、发电机、高压电动机、电力电容、电力电缆、避雷器等绝缘电阻的理想测试仪器。

第二章产品介绍一、产品特性1、有多种电压输出选择RT2000A(2500V/5000V)、RT2000B(500V、1000V、2500V、5000V)，测量电阻量程范围可达0～200GΩ，电阻量程范围可自动转换，并有相应的指示。

2、两种方式同步显示绝缘阻值。

机械指针采用超薄型张丝结构抗震能力强。

机械指针的采用可容易观察绝缘电阻的变化范围，点阵液晶屏的采用可指导用户操作仪表并可精确得出测量结果。

3、机械表头与液晶屏合二为一。

双刻度显示，量程自动转换。

彩色刻度易于读识，并有LED显示相应色彩。

4、采用嵌入式工业单片机和实时操作软件系统。

自动化程度高、抗干扰能力强，仪器可自动计算吸收比和极化指数，无须人工干预。

5、操作界面友好，各种测量结果具有防掉电功能，可连续存储20次的测量结果。

6、仪表产生高压时，有提示音输出。

7、内置残留高压放电电路，测试完毕可自动放掉被测设备上的残留高压。

8、交直流两用，配置可充电池和交流适配器。

9、仪表采用便携式设计，便于野外操作。
