严格按照国际 “无线电干扰委员会 ”（CISPR）的规定，采用工 业波段27.12MHZ，并设计有高周波 稳定器和高周波漏磁抑制装置，对 外界设备的于扰极小。
u The industrial wave band of 27.12 / 40. 68MHZ is adopted in accordance with the "International Special Committee On Radio Interference (CISPR)". A frequency stabilizer and a long frequency magnetic leakage suppressor are provided, so the interference caused to other equipments is extremely low.
u The high sensitivity spark suppression circuit is used for testing unbalanced current of sparks. The oscillator circuit can be cut immediately if any spark is caused (The alarm light will be ON at this time) so as to ensure the lowest damage rate to moulds, materials and products.
u The high precision and widely used four-column positioning design is adopted, ensuring reliable operation. The overvoltage and over current protection is provided for disconnecting high voltage during abnormal conditions so as to protect the oscillator and rectifier and prevent frequency drift due to misoperation.
