Fluke 378 FC

מאפיינים מרכזיים

צבת זרם מדגם Fluke 378 FC True RMS עושה שימוש בטכנולוגיית ™FieldSense, המאפשרת להפוך בדיקות למהירות ובטוחות יותר, והכל ללא מגע עם מוליך חי (מחושמל). מתקבלות מדידות מתח וזרם מדויקות לסת הצבתות. כל מה מה שנדרש לעשות הוא לחבר את כבל הבדיקה השחור להארקה חשמלית כלשהי, לשים את המוליך בין הצבתות ולקבל בצג מדידות מתח וזרם מהימנות ומדויקות.

  • מדידת מתח וזרם בעזרת הצבת
  • בדיקה מהירה ובטוחה יותר – כל זה ללא צורך במגע במוליך "חי" – בעזרת שימוש ב FieldSense™ technology
  • אינדיקציה לאיכות חשמל – מציג באם הציוד או קו החשמל לא תקין.
  • בדיקות תלת פאזיות של מתח וזרם ב 3 שלבים מהירים.
