绝缘电阻率测试仪安全注意事项
4.1 使用前务必详阅此说明书,并遵照指示步骤,依次操作。
4.2 请勿使用非原厂提供之附件,以免发生危险。
4.3 进行测试时,本仪器测量端高压输出端上有直流高压输出,严禁人体接触 ,以免触电。
4.4 为避免测试棒本身绝缘泄漏造成误差,接仪器测量端输入的测试棒应尽可 能悬空,不与外界物体相碰。
4.5 当被测物绝缘电阻值高,且测量出现指针不稳现象时,可将仪器测量线屏 蔽端夹子接上。 例如:对电缆测缆芯与缆壳的绝缘时,除将被测物两 端分 别接于输入端与高压 端,再将电缆壳 ,芯之间的内层绝缘物接仪器 “G”,以消 除因 表面漏电而 引起的测量误差。也可用加屏蔽盒的方法, 即将被测物置于金属屏蔽盒内,接上测量线。
绝缘电阻率测试仪同时测出电阻两端的电压V和流过电阻的电流I,通过内部的大规模集成电路完成电压除以电流的计算,然后把所得到的结果经过A/D转换后以数字显示出电阻值,即便是电阻两端的电压V和流过电阻的电流I是同时变化,其显示的电阻值不象普通高阻计那样因被测电压V的变化或电流I的变化而变,所以, 即使测量电压、被测量电阻、电源电压等发生变化对其结果影响不大,其测量精度很高。从理论上讲其误差可以做到零。而实际误差可以做到千分之几或万分之几。
绝缘电阻率测试仪注意事项
★★★★★★★★★★★★★
仪器使用前请仔细阅读以下内容,否则将造成仪器损坏或电击情况。
1. ★检查仪器后面板电压量程是否置于10V档,电流电阻量程是否置于104档。
2. ★接通电源调零,(注意此时主机不得与屏蔽箱线路连接)在“Rx”两端开路的情况下,调零使电流表的显示为0000。然后关机。
3. ★将待测试样平铺在不保护电极正中央,然后用保护电极压住样品,再插入被保护电极(不保护电极、保护电极、被保护电极应同轴且确认电极之间无短路)。
4. ★测体积电阻时测试按钮拨到Rv边,测表面电阻时测试按钮拨到Rs边,
5. ★接好测试线,将测试线将主机与屏蔽箱连接好。量程置于104档,打开主机后面板电源开关按钮。从仪器后面板调电压按钮到所要求的测量电压。(比如:GBT 1692-2008 硫化橡胶 绝缘电阻率的测定 标准中注明要求在500V电压进行测定,那么电压就要升到500V)
6. ★电流电阻量程按钮从低档位逐渐拨高档,每拨一次停留1-2秒观察显示数字,当被测电阻大于仪器测量量程时,电阻表显示“1”,此时应继续将仪器拨到量程更高的位置。测量仪器有显示值时应停下,在1min的电化时间后测量电阻,当前的数字乘以档次即是被测电阻。
7. ★测试完毕先将量程拨至(104)档,然后将测量电压拨至10V档,zui后将测试按钮拨到中央位置后关闭电源。然后进行下一次测试。
8. ★应在“Rx”两端开路时调零,一般一次调零后在测试过程中不需再调零。
9. ★禁止将“RX”两端短路,以免微电流放大器受大电流冲击。
10. ★不得在测试过程中不要随意改动测量电压。
11. ★测量时从低次档逐渐拨往高次档。
12. ★接通电源后,手指不能触及高压线的金属部分。
13. ★不得测试过程中不能触摸微电流测试端。
14. ★在测量高阻时,应采用屏蔽盒将被测物体屏蔽。
15. ★严禁在试测过程随意改变电压量程及在通电过程中打开主机。
16. ★严禁电流电阻量程未在104档及电压在10V档,更换试样。

绝缘电阻率测试仪使用方法
6.1接好电源线
确保电源为220VAC/50Hz
6.2接通电源
将电流电阻量程置于 104 档,电压量程置于10V,然后开机。
6.3调零
在“Rx”两端开路的情况下,调零使电流表的显示为0000 .注意:在“Rx”两端不开路,如接在电阻箱或被测量物体上时调零后测量会产生很大的误差。一般一次调零后在测试过程中不需再调零。 完毕后关机。
6.4连接线路
接好测试线,将测试线将主机与屏蔽箱连接好,测体积电阻时测试按钮拨到Rv边,测表面电阻时测试按钮拨到Rs边。然后开机。
6.5选择合适的测量电压
★电压选择开关在后面板,注意,在测试过程中不要随意改动测量电压,可能因电压的过高或电流过大损坏被测试器件或测试仪器;
6.6测试
测量时从低档位逐渐拔往高档,每拨一次稍停留1~2秒以使观察显示数字, 当被测电阻大于仪器测量量程时,电阻表显示“1”,此时应继续将仪器拨到量程更高的位置,当测量仪器有显示值时应停下,当前的数字乘以档次即是被测电阻值。当有显示数字时不要再往更高次档拨,否测仪器会过量程,机内保护电路开始工作,仪器测量准确度会下降。
6.7 测试完毕将电阻电流量程拔至“104 ”档,电压量程调至10V后关闭电源
★每测量一次均应将量程开关拨回到104“调零”档的量程位置以免开机或测量端短路时而损坏仪器。
6.8 测量电流及1015Ω以上超高电阻的测量应用测量电流后用欧姆定律以电压除以电流计算电阻的方法,详见8.5节内容。
6.9 体积电阻和表面电阻转换
★在测试过程中,使用屏蔽箱在进行体积电阻和表面电阻转换时,必须把电源关闭后进行档位转换,否则会导致电压冲击到主机无法显示或损坏。

Security considerations
4.1 be sure to read the manual before use and follow the instructions step, operating in turn.
4.2 do not use the original factory to provide the attachment, thank you for your cooperation.
4.3 during the test, the instrument measuring the dc high voltage output high voltage output, it is strictly prohibited to human exposure, so as to avoid electric shock.
4.4 to avoid test bar insulation leakage error caused by itself, by instrument measuring the input can be hung up test bar, no object collision with the outside world.
Analyte 4.5 when a high insulation resistance, and measure the instability phenomenon appear Pointers, line screen can be measured All the clip connected. For example: the insulation of the cable and cable to cable measured shell, in addition to the analyte to the two end points Don't pick up the input and the high pressure side, and then to a shell, the cable core between inner insulation instruments \"G\", to eliminate the error of measurement caused by surface leakage. Method can also be used with shielding box, is about to be tested on the metal shielding box, measuring line.
At the ends of the resistance is measured at the same time current through the resistor voltage V and I, through the internal voltage divided by the current calculation of large scale integrated circuit is complete, then put the results after A/D conversion to digital shows resistance, even at the ends of the resistance current through the resistor voltage V and I change at the same time, the display of the resistance is not like ordinary high resistance meter by measuring the change of the V voltage or current I change and change, so, even if the measured voltage, by measuring the resistance and voltage change has A little influence on the results, the measuring precision is high. In theory it can achieve zero error. The actual error can be done a few parts per thousand or very few.
