The Testec TT-HV 200 and TT-HV 400 passive oscilloscope probes deliver precision high-voltage measurements for professional electronic design applications. With a 300MHz bandwidth and 100:1 attenuation ratio, these probes safely measure up to 2kV (TT-HV 200) or 4kV (TT-HV 400) DC + peak AC, making them ideal for power electronics, automotive systems, and industrial equipment testing.
Key terms and their relevance:
- CAT II Safety: Certified for measurements on circuits directly connected to mains outlets (up to 1000Vrms), ensuring safe operation in common industrial environments [4][19].
- Pollution Degree 2: Designed for dry, non-conductive environments with temporary condensation, aligning with IEC 61010-031 standards for reliability [2][4].
- Input Impedance (100MΩ/5pF): Minimises circuit loading, preserving signal integrity during high-voltage tests [2][8].
Unique features include a ±2% DC accuracy, 8–25pF compensation range for precise waveform matching, and a rugged 1.2m cable rated for altitudes up to 3000m. Engineers should prioritise these probes for their compliance with EU RoHS2 and IEC safety standards, ensuring both measurement accuracy and user protection in demanding applications.
