产品详情
斯泰科STC-001 表面电阻测试仪是通过测量防静电产品表面的电阻，从而检测防静电产品的防静电能力，本仪器遵循ASTM标准D-257测试方法，测试时通过测试仪底部的两根平行铜电极快捷地测试物体表面的电阻，只需放置在需要测量的物体表面及按下红色的按键，仪器上的十个103-1012LED将其中一个测试数值亮起，亮起的LED灯即为所测物体的表面电阻。

The measurements of both surface resistivity and resistance to ground. Giving simple repeatable measurements of conductive, static dissipative and insulative surface. The checker employs the ASTM standard D-257 method of parallel bar sensing. Ranging is automatic due to the use of high speed OP-AMP integrated circuits being linear, with changeover points + or – 1/2 decade on a logarithmic scale ( 1 or 10% from mean value per unit).

Operation
Remove the battery compartment and panel and check that a good quality PP3 alkaline battery has been fitted. Hold the checker away form any surface and press the test button, the insulative red LED light.
Place the checker onto the surface that requires testing, again press the test button and hold. The LED that illuminates constantly is the decade measured.
10/3=1 kilohm Green LED 10/9 = 1,000 meg ohms Yellow LED
10/4=10kilohms Green LED 10/10=10,000megohms Yellow LED
10/5=100kilohms Green LED 10/11=100,000megohms Yellow LED
10/6=1megohm Yellow LED 10/12=1,000,000megohms Red LED
10/7=10megohms Yellow LED >10/12=Insulative Red LED
10/8=100megohms Yellow LED
Checking Resistance to ground
Insert the ground/earth leakage lead into the ground/earth leakage socket. This is lates the test probe ont the right side of the meter. (The same blue as the socket). Connect the croc clip to your ground connection.
Place the checker on to the surface to be tested, press and hold the test button. The LED that illuminates constantly is the decade measured. The
Measurement will be resistance to ground in ohms instead of ohms per square.
