以 1 伏和 10 伏為增量

進(jìn)行測(cè)量 PFM-711B 使用雙量程來測(cè)量正極和負(fù)極電荷的表面電壓和靜電勢(shì)。在 kV/Inch 范圍內(nèi)，PFM-711B 將在距離帶電表面 1" (25mm) 處以 10 伏的增量指示從 0 到 ±20,000 伏的靜電場(chǎng)電壓。在 V/英寸范圍內(nèi)，場(chǎng)計(jì)測(cè)量場(chǎng)在距離帶電表面 1" (25mm) 處，密度從 0 到 ±1,999 伏，增量為 1 伏。該儀器易于使用，其控制裝置專為單手操作而設(shè)計(jì)。

提供接地參考

PFM-711B 場(chǎng)計(jì)外殼是導(dǎo)電的。它為其測(cè)量電路提供接地參考。為獲得準(zhǔn)確的測(cè)量結(jié)果，手持儀表的人員必須正確接地，或者儀表與安裝在外殼背面的 10 毫米按扣進(jìn)行接地連接。通過佩戴正確接地的功能性腕帶將外殼接地。打開儀表并選擇所需的范圍。按下 ZERO 控件將顯示調(diào)整為零 (0) 伏。

用于精確測(cè)量的靶心

測(cè)距燈有助于定位儀器以進(jìn)行精確測(cè)量。將 PFM-711B 場(chǎng)強(qiáng)計(jì)的前傳感器與被測(cè)表面或物體大約 1" (25mm) 對(duì)齊。將儀器移向或遠(yuǎn)離表面，直到測(cè)距燈聚焦在測(cè)試表面上。一旦場(chǎng)強(qiáng)計(jì)正確放置后，PFM-711B 將在其顯示屏上顯示測(cè)得的靜電場(chǎng)。

與記錄設(shè)備一起

使用 PFM-711B 是 ESD 控制市場(chǎng)中最靈活的現(xiàn)場(chǎng)儀表。結(jié)合各種附件，它可以執(zhí)行許多不同的測(cè)量來分析靜態(tài)敏感過程或環(huán)境。模擬輸出與 XY 繪圖儀、模擬數(shù)據(jù)記錄設(shè)備或 Prostat PGA-710B 自動(dòng)分析系統(tǒng)結(jié)合使用時(shí)可以記錄測(cè)量結(jié)果. （不包括錄音設(shè)備和電纜。）

持久耐用的電池

PFM-711B 使用 9 伏堿性電池（隨附），可提供大約 30 小時(shí)的使用壽命。顯示屏旨在指示電池電量不足時(shí)。低電量指示器可方便地編程為 7.2 直流電壓，這是準(zhǔn)確測(cè)量所需的最低電壓。

Product Overview：

Uses a Chopper-Stabilized Sensor

The PFM-711B is an accurate, portable electrostatic field measuring device that is easy to use and designed for one hand operation. The PFM-711B is a digital, electronic chopper design, which allows the instrument to make electrostatic field measurements in areas where ionized air is present. Used by itself, the PFM-711B will measure electrostatic fields emanating from virtually any flat surface or object.

Measure in 1 Volt and 10 Volt Increments

The PFM-711B uses a dual range for measuring surface voltage and electrostatic potentials in both positive and negative polarity charges. In the kV/Inch range, the PFM-711B will indicate electrostatic field voltage from 0 to ±20,000 volts in 10 volt increments at 1" (25mm) distance from the charged surface. In the V/Inch range, the field meter measures field density from 0 to ±1,999 volts in 1 volt increments at 1" (25mm) distance from the charged surface. The instrument is easy to use and its controls are designed for one hand operation.

Provides a Ground Reference

The PFM-711B Fieldmeter case is conductive. It provides the ground reference for its measuring circuit. For accurate measurements, it is necessary that the person holding the meter be properly grounded, or the meter has a ground connection made to the 10 mm snap fastener mounted on back of case. Ground the case by wearing a functional wrist strap that is properly grounded. Turn the meter on and select the desired range. Adjust the display to zero (0) volts by pressing the ZERO control.

Bulls Eye for Accurate Measurements

The ranging lights help position the instrument for accurate measurements. Align the front sensor of the PFM-711B Field Meter approximately 1" (25mm) from the surface or object being measured. Move the instrument toward, or away from the surface until the ranging lights are focused on the test surface. Once the field meter is properly positioned, the PFM-711B will indicate the electrostatic field measured on its display.

Use it with a Recording Device

The PFM-711B is the most flexible field meter in the ESD control marketplace. Combined with a variety of accessories, it can perform many different measurements to analyze the static sensitive process or environment.The analog output allows documentation of measurements when used in conjunction with X-Y plotter, analog data recording device, or the Prostat PGA-710B Autoanalysis System. (Recording device and cable not included.)

Long Lasting Battery

The PFM-711B uses a 9 volt alkaline battery (included), which provides an approximate life of 30 hours. The display is designed to indicate when the battery is low. The low battery indicator is conveniently programmed to come in at 7.2 DC volts, which is the minimum voltage required for accurate measurements.
