2 With the EF-S series, constant checking of static electricity is possible while a production line is running. Managing static electricity is commonly a difficult task in workplaces where high-density, high-precision electrical equipment is being utilized. assembled. Static electricity cannot be seen with the eye, so measurement of surface potentials while the production line is running using the EF-S series provides a new way to assess its levels accurately so that it can be constantly managed. Ultra-thin type ionizer ER-VW EF-S Easy-to-read 2-color dual display The controller is equipped with a red and a green display. Current values and threshold values can be viewed at a glance. mm.94 in thickness Threshold value setting display Green LED, 4 digits Current measurement value display Red LED, 4 digits Large jog switch Large MODE key Suitable for measuring under severe conditions High-precision design with a repeatability precision of. % F.S. Even very slight differences in potential will not be skipped over. A variety of functions for a wide range of applications A large number of functions for a variety of applications are available, including -adjust, hysteresis setting, window comparator output, and potential / potential peak hold (external timing input) measurement. Lightweight and compact for easy setup in any location The sensor head only weighs 9 g. Installation can be carried out easily using just a bracket so that it is suitable for use in a wide variety of applications. In addition, power consumption is low so the devices can be utilized without concerns of high running costs mm.5 in Potential display Threshold value H (Hysteresis) 2 mm.472 in 58 mm 2.28 in Threshold value Potential display Window comparator mode OUT H (Hysteresis) ON OFF Easy data management using analog output A device such as a data logger can be used to collect and analyze data, which is useful when carrying out inspections of factors such as ionizer setup angle and the number of devices installed.
