PROSTAT静电场测试仪PFM-711A介绍
PFM-711A现场仪表是一种精确的静电场测量设备。PFM-711A电路是数字电子斩波器设计，可让该仪器在存在离子化空气的区域进行静电场测量。
为了获得准确，可重复的性能，PFM-711A必须在正常操作期间接地。PFM-711A单独使用，可以测量几乎任何平面或物体发出的静电场。
以1伏和10伏为增量进行测量
在KV / INCH范围内，PFM-711A会在距充电表面一英寸的距离内以10伏的增量指示从0到±20,000伏的静电场电压。
在V / INCH范围内，仪器在距充电表面一英寸的距离内以1伏为增量测量0至±1,999伏的场密度。该仪器易于使用，其控件专为单手操作而设计。
提供地面参考
PFM-711A表壳是导电的。它为其测量电路提供接地参考。为了进行准确的测量，必须将仪表的人员正确接地，或者将仪表的外壳上的金属搭扣与地面连接。
戴上正确接地的功能性腕带，使外壳接地。通过选择所需的范围打开仪表。向下按SAMPLE HOLD按钮，使其锁定在较低或SAMPLE位置，并且在仪表显示屏上不显示HOLD。通过旋转零位控件将显示调整为零（0）伏。
The PFM-711A Field Meter is an accurate electrostatic field measuring device. The PFM-711A circuitry is a digital, electronic chopper design, which allows the instrument to make electrostatic field measurements in areas where ionized air is present.
For accurate, repeatable performance, the PFM-711A must be grounded during normal operations. Used by itself, the PFM-711A will measure electrostatic fields emanating from virtually any flat surface or object.
Measure in 1 Volt and 10 Volt Increments
In the KV/INCH range, the PFM-711A will indicate electrostatic field voltage from 0 to ±20,000 volts in 10 volt increments at one inch distance from the charged surface.
In the V/INCH range, the instrument measures field density from 0 to ±1,999 volts in 1 volt increments at one inch 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-711A meter 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 metal snap on the case.
Ground the case by wearing a functional wrist strap that is properly grounded. Turn the meter on by selecting the desired range. Press the SAMPLE HOLD button down so that it latches in the lower or SAMPLE position, and HOLD is not indicated in the meter display. Adjust the display to zero (0) volts by rotating the ZERO control.
