The Cal Test CT4066 allows safe, accurate measurement between two voltage points where neither point is referenced to ground. The CT4066 offers both a 25 MHz bandwidth and a 15 MHz bandwidth. The 25 MHz bandwidth is for the 50x and 200x attenuation settings and the 15 MHz bandwidth is for the 20x attenuation setting.
Includes:
• (2) Pincer Clips, black & red
• (2) Alligator Clips, black & red
• (2) Sheathed 4 mm banana plug test leads, silicone jacketed, black & red
• Insulated BNC cable, 100 cm
• 9 V Power adapter included (CT3957)
