Wide Compatibility & Multi-Channel Measurement: Suitable for SF6 switches, GIS, vacuum switches, oil switches, vacuum contactors, and special circuit breakers. Measures up to 12 contacts (6 main + 6 auxiliary) simultaneously. One operation captures time, bounce, speed, coil current/resistance, etc. Features low-voltage trip testing, circuit breaker life testing, and a high-speed thermal printer.
User-Friendly Display: 7-inch color screen, clear in sunlight. Menu-driven with one-key operation, supports Chinese/English input. Displays time, stroke, speed, and waveforms on one screen; average velocity marked on stroke curve.
Integrated Power Supply & Protection: Built-in DC 20-270V, 20A adjustable power supply. Short-circuit protection halts output within 1ms with audible alert. Dual-circuit design ensures testing continuity if one control circuit fails.
Easy Sensor Installation: Compatible with linear and 360 rotation sensors; multifunctional fixing joints simplify installation. Linear sensor length adjustable from 30-1000 mm without factory reprogramming.
Data Storage: Stores up to 100 test sets with built-in real-time clock for easy archiving.
Connectivity: USB and RS232 interfaces for data export to USB drive or computer; RS232 supports optional online operation.
Anti-Interference: Reliable operation even in 500 kV substations.
