Product features

• 7‑inch high‑resolution LCD shows real‑time voltage, current, time, system status and prompts.
• Localized on‑screen interface for in‑field operation.
• Tactile push‑button controls for secure configuration and operation.
• Digital calibration replaces potentiometers for repeatable field adjustments (password protected).
• Programmable test transformer ratios (button‑configurable) to support multi‑voltage testing with one console.
• Guided workflow with status prompts enables intuitive operation without consulting manuals.
• Auto‑Timing mode: automatic timing at target voltage, result display and auto‑reset.
• Manual Timing mode: operator‑initiated timing with auto‑reset on test completion.
• Manual voltage ramp control with automatic limit detection and overvoltage protection; ramp speed configurable (default 1 kV/s).
• Hybrid hardware/software noise suppression for industrial stability and EMI immunity.
