Description
描述
The AlphaLab Voltage Touch Monitor enables personnel to identify voltage problems that usually remain hidden. The monitor reads the voltage on a finger (which is identical to the voltage at every other point on the body). It can detect as little as 1/10 volt in two modes: DC and AC/Spikes (ESD transients). In the DC mode, the displayed voltage is either positive or negative, and is usually very low if grounding is being worn and is functioning properly. Higher DC voltages (even while grounded) occur if a DC ionizer is blowing too close or if the person rubs against a high-static material or comes in contact with metal at a DC potential. If personal grounding is not being used, any DC signal can build up over time, and the DC mode continues to show the instantaneous body voltage as it changes. In the AC/Spikes mode, any transient voltage spike at least 1/2 millisecond long is temporarily displayed. If there are several consecutive spikes, only the highest is displayed, regardless of polarity. If the signal is a repetitive (AC) wave, the peak voltage is displayed, but always as a positive number. Even when proper grounding is worn, several tens of volts often occur with transients and AC. Maximum error for DC and AC is only 2 of the reading /- 0.1 volt.
的alphalab電壓觸摸監(jiān)視器使人員識(shí)別電壓的問(wèn)題，通常是隱藏的。顯示器讀取一個(gè)手指上的電壓（在身體的每一個(gè)點(diǎn)上都是相同的電壓）。它可以檢測(cè)為1 / 10伏在2種模式：直流和交流/尖峰（靜電放電）。在直流模式下，所顯示的電壓是正的或負(fù)的，通常是非常低的，如果接地被磨損和運(yùn)作正常。較高的直流電壓（即使是接地的）如果一個(gè)直流靜電是吹太近或如果人摩擦高靜電材料或在直流電位與金屬接觸發(fā)生。如果不使用個(gè)人的接地，任何直流信號(hào)都可以隨時(shí)間而生成，而直流模式則繼續(xù)顯示瞬時(shí)體電壓隨時(shí)間變化的變化。在交流/尖峰模式，任何瞬態(tài)電壓尖峰至少1 / 2毫秒長(zhǎng)的臨時(shí)顯示。如果有幾個(gè)連續(xù)的尖峰，只有最高的顯示，無(wú)論極性。如果信號(hào)是一個(gè)重復(fù)（交流）波，峰值電壓顯示，但始終作為一個(gè)積極的數(shù)字。即使正確的接地是否磨損，幾十伏常出現(xiàn)瞬變和AC的最大誤差為直流和交流是只有2的閱讀/ 0.1伏。
