Description
描述
The SVM2 is a handheld static electricity meter used to measure the magnitude and polarity of static charge on objects or surfaces. It is typically held 1 (25 mm) from the test surface. On metallic or conductive surface, the meter measures the voltage on the surface. (As with any electrostatic voltmeter, the displayed reading depends somewhat on the size of the object being measured and the distance between the object and the sensor.) On insulating surfaces, voltage is not a well-defined number. In this case, the meter reads a number proportional to the static charge present.
这是一种手持式静电SVM2计用来测量的大小和物体或表面的静电荷极性。它通常举行1（25毫米）从测试表面。在金属或导电表面，测量表面上的电压。（如用任何静电计，所显示的读数在一定程度上取决于被测物体的大小和物体与传感器之间的距离），在绝缘表面，电压不是一个定义良好的数字。在这种情况下，该表读取静态电荷的比例。
The SVM2 has high sensitivity (resolution), and can detect even a 1 volt charge anywhere within its full range of 29,999 to -29,999 volts. Thus it is easy to measure whether a given process is increasing or decreasing the static electricity present, even if the increase or decrease is by a tiny fraction. The meter reads the actual static signal, but it also captures and stores the highest positive and highest negative signals that were experienced since the last time that the Reset button was pressed. These peak and can be displayed at any later time. The peak function has a window time of 0.005 seconds (which is much faster than the display) so even very quick peaks are captured and stored. There is also a user-settable alarm. The alarm will sound if the signal (whether or -) ever exceeds the value set by the user for at least 0.005 seconds. The alarm can be reset or muted at any time.
该SVM2具有很高的灵敏度（分辨率），并且能检测到1伏充电全范围内的任何地方29999 – 29999伏特。因此，很容易衡量一个给定的过程是增加或减少静电的存在，即使增加或减少是由一个小部分。该表读取实际的静态信号，但它也捕获和存储的最高积极的和最高的负信号，自上次经历的重置按钮被按下。这些峰，可以显示在任何以后的时间。峰值函数有一个窗口的时间为0.005秒（这是远远快于显示），所以即使是非常快速的峰值捕获和存储。还有一个用户可设置报警。如果信号（无论是）是否超过了用户所设定的值至少0.005秒，则该警报将声音。该报警可以重置或静音在任何时间。
