High Voltage Insulation / Continuity / Earth High voltage insulation testers MI 3211 TeraOhmHP 10 kV The MI 3211 TeraOhmHP 10 kV is a high power, portable, battery or mains powered test instrument with excellent IP protection (IP65), designed for analysing insulation resistance by using high DC test voltages of up to 10 kV. Because of its robustness (CAT IV measuring category) and high immunity to radiated EM fields, it is best suited for demanding industrial environments. Touch screen or key manipulation via menudriven LCD enables easy and transparent selection of different measurement methods and easy entry of data. Newly designed test leads have coded banana connectors for proper connection and locking to protect them against unwanted or accidental removal. MEASURING FUNCTIONS • • • • • Insulation resistance measurement; Diagnostic test (PI, DAR, DD); Step voltage test; Withstanding voltage test (DC) up to 10 kV; Voltage and frequency measurement up to 999 V TRMS; • Capacitance measurements. KEY FEATURES • Insulation resistance measurements of up to 20 TΩ. • Safety rated category up to CAT IV 600 V to 3000 m. • Dual-case design. • Coded banana connectors with locking feature. • Newly designed HV crocodiles with a better grip. • Li-ion battery 4400 mAh. • Adjustable test voltage (50 V...10 kV) 50 V and 100 V step. • Maximum short circuit/charge current: > 4 mA (mains supply) or >2.4mA (battery supply). • Charging rate for capacitive load <2.7s / μF at 10 kV. • Discharging rate for capacitive load < 0.24 s / μF at 10 kV (mains supply). 8 GB memory SD card for data saving.
