1. Time measurement: 12 fracture intrinsic points, closing time, with the same period, phase with the same period.
2. Reclosing measurement: each fracture closing - minute, minute - closing, minute - closing - minute process time, one minute time,one closing time, two closing time, gold short time, no current value.
3. Bounce measurement: closing bounce time, bounce times, bounce waveform of each fracture, rebound amplitude of each fracture.
4. Velocity measurement: stiffness, maximum velocity, time-travel characteristic curve.
5. Current measurement: the current value of the closing coil and the closing coil, the current waveform
6. Action voltage measurement: digital adjustable circuit breaker action power supply, automatic completion of low voltage circuit breaker action test, measurement of circuit breaker action voltage value.

• Multi-Channel, Intelligent Detection

  • Equipped with 12 independent measurement channels that automatically identify and display the real-time status (open/close) of each breaker contact.

  • Provides clear wiring verification prompts, significantly reducing setup errors and enhancing test reliability.

• Advanced Display & Intuitive Operation

  • Features a large, sunlight-readable grayscale touchscreen that eliminates glare for clear visibility in any environment.

  • User-friendly graphical menu interface (in English) with step-by-step operation guides ensures straightforward and efficient testing.

• Comprehensive Testing Capabilities

  • Performs complete timing and travel analysis for vacuum, SF6, oil, and other high-voltage and medium-voltage circuit breakers.

  • Supports reclosing sequence tests (e.g., O-C, C-O, O-C-O) and minimum operating voltage determination for both opening and closing coils.

  • Specialized function for testing single-coil vacuum contactors.

• Integrated Data Management & Analysis

  • Capable of storing up to 50 complete test reports directly on the device for record-keeping and comparison.

  • Powerful graphical analysis tools display synchronized waveforms and numerical results on one screen for in-depth diagnostics and reporting.

• Built-in Safety & Protection

  • Incorporates automatic time-delay protection, which safely cuts off the coil supply voltage immediately after breaker operation to protect both the instrument and the equipment under test.
