LST-122体积表面电阻率测试仪测量方法介绍

*电阻测量法Resistance measurement：

1，连接Connect：

2，北京中航鼎力仪器设备有限公司LST-122 样品放置Sample placement：

A，将测试样品放在电极箱的背电极平面上，再将另外2个电极（内电极和环形电极）放在测试样品上，盖上透明圆形塑料“隔离”

The test sample was placed on the back electrode plane of the electrode box and the other two electrodes(inner electrode and annular electrode) were placed on the test sample，Cover with transparent round plastic"Isolation"

B，将电极箱内的红色连接线夹在内电极上，黑色连接线夹在环形电极上，关闭电极箱

Clip the red connecting wire in the electrode box on the inner electrode, the black connecting wire on the annular electrode, close the electrode box

C，并将电极箱的选择开关拨至“RV”位置，测量体积电阻；或拨至“RS”位置，测量表面电阻

The selection switch of the electrode box is set to the "RV" position to measure the volume resistance, or to the "RS" position to measure the surface resistance

3，校零：打开电源 → 放在测量电压就近的 .000档位 →“保持”往下（其他白色的开关往上） → 10⁵Ω档位 → 开始调零

Zero：Power on → In gear .000 near the measuring voltage → Hold down (other white switches up) →Stall 10⁵ Ω → Start zeroing 4，测量：在10⁵Ω档位 → 检查数值（若出现1，每隔3-5秒逐渐提高档位，直至出现非1的数值）→ “保持”向上→稍等→

出现H，读数值，乘以相应档位

Measure： At 10⁵Ω stalls → Check the value (if 1 occurs, gradually raise the gear every 3-5 seconds until non-1 occurs)→ Keep it up → Half a moment! →H, read the values, multiply by the corresponding gear

5，测量结束：“保持”往下 →回到 .000档位 → 10⁵Ω档位 （此时可以更换样品或者结束）→ 关闭电源

End of measurement：Keep it down →Back to .000 gear →Gear 10⁵Ω(Samples can be replaced or finished) →Power off

*微电流测量法Micro current measurement：

1 2，连接和样品放置与电阻测量法相同：Connection and sample placement are the same as resistance measurements

3，校零：打开电源 → 放在测量电压就近的 .000档位 →“保持”往下，拨向“电流”和“平衡” → 10^-5A档位 → 开始调零

Zero：Power on → In gear .000 near the measuring voltage → Hold down and dial to current and balance → 10^-5 A gear

→ Start zeroing

4，测量：“平衡”拨回“测量”→ 在10⁵A档位 → 检查数值（若出现0，每隔3-5秒逐渐提高档位，直至出现非0的数值）→

“保持”向上→稍等→ 出现H，读数值，乘以相应档位

Measure： "Balance" dial back "Measure" → At 10⁵A stalls → Check the value (if 0 occurs, gradually raise the gear every 3-5 seconds until non-0 occurs) → Keep it up → Half a moment! →H, read the values, multiply by the corresponding gear

5，测量结束：“保持”往下 →回到 .000档位 → 10^-5A档位 （此时可以更换样品或者结束）→ 关闭电源

End of measurement：Keep it down →Back to .000 gear →Gear 10^-5 A gear (Samples can be replaced or finished)→Power off

6，电阻 = 电压 ÷ 电流，电阻率 换算公式 请在说明书中查找

Resistance = Voltage ÷ Current，Resistivity Conversion formula Please find in the instruction manual
