RCD/LOOP/PAT TESTER
เครื่องทดสอบ RCD TESTER เป็นมิเตอร์ที่ใช้วัดค่า RCD (ELCB) โดยจะวัดค่าเวลาในการตัดวงจร (RCD Trip Time) ได้ ณ จุดจ่ายไฟโดยตรง เช่น ที่เต้าเสียบ ในมิเตอร์รุ่น 5406A จะควบคุมการทำงานด้วยระบบไมโครโปรเซสเซอร์ ทำให้กระแสที่ใช้ในขณะทดสอบมีค่าคงที่ แม้ว่าแรงดันของแหล่งจ่ายจะเปลี่ยนแปลงไปก็ตาม จึงทำให้ค่าที่วัดได้มีความถูกต้องยิ่งขึ้น
