• Resistance measurement capability up to 10 PΩ (10¹⁶ Ω)
• Built-in ±1,000 V voltage source for bias testing
• Battery operation eliminates AC power line noise for ultra-clean measurements
• 4.3-inch color LCD with graphical viewing modes (Meter, Graph, Histogram, Roll View)
• High-speed reading rate up to 20,000 readings/second
• Less than 20 μV burden voltage in lowest current range
• Input impedance exceeding 200 TΩ for up to 20 V voltage measurement
• Charge measurement capability from 2 nC with 6.5-digit resolution
• Temperature and humidity measurement support via compatible sensors
• Interfaces: USB 2.0, LAN, GPIB, LXI Core
• Real-time noise monitoring and optional Setup Integrity Checker for noise isolation
