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.
這是一種手持式靜電SVM2計用來測量的大小和物體或表面的靜電荷極性。它通常舉行1（25毫米）從測試表面。在金屬或導電表面，測量表面上的電壓。（如用任何靜電計，所顯示的讀數在一定程度上取決于被測物體的大小和物體與傳感器之間的距離），在絕緣表面，電壓不是一個定義良好的數字。在這種情況下，該表讀取靜態電荷的比例。
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.
該SVM2具有很高的靈敏度（分辨率），并且能檢測到1伏充電全范圍內的任何地方29999 – 29999伏特。因此，很容易衡量一個給定的過程是增加或減少靜電的存在，即使增加或減少是由一個小部分。該表讀取實際的靜態信號，但它也捕獲和存儲的最高積極的和最高的負信號，自上次經歷的重置按鈕被按下。這些峰，可以顯示在任何以后的時間。峰值函數有一個窗口的時間為0.005秒（這是遠遠快于顯示），所以即使是非常快速的峰值捕獲和存儲。還有一個用戶可設置報警。如果信號（無論是）是否超過了用戶所設定的值至少0.005秒，則該警報將聲音。該報警可以重置或靜音在任何時間。
