Suitable for SF6 switches, GIS combination devices, vacuum switches, oil switches, vacuum contactors, and special circuit breakers (train circuit breakers) produced domestically and internationally.

At the same time, it can measure 12 metal contact fracture surfaces, 6 main fracture surfaces, and 6 auxiliary fracture surfaces. Once the circuit breaker is activated, data and waveforms such as time, bounce frequency and time, speed, coil current, and coil resistance are obtained.

It has functions such as energy storage, automatic and manual low jump tests, circuit breaker life tests, and (optional locking power supply and dry contact control). Equipped with a high-speed thermal printer, it is convenient to print test data on site.

7-inch color high brightness screen (adjustable brightness), clear and visible even when operated under the sun. Menu based operation, quick testing interface, one click operation, supports both Chinese and English input. The 12 channel fracture status is displayed in Chinese, with time, travel, speed, and waveform displayed on the same screen, without the need to flip pages to view data. Analyze the average speed of the specified section and mark it on the travel curve for easy viewing. Built in 21 conventional types of circuit breaker speed definitions, simply select the switch type and measure with one click.
 
Integrated operation power supply inside the machine, no need for on-site secondary power supply, easy and fast to use. Can provide adjustable power supply of DC20-270V with a current of 20A. It has a short-circuit protection function. In case of a short circuit, the voltage and current output will be stopped for 1ms, and a beep alarm sound will be emitted to prompt the operator to check the circuit. Dual circuit power supply design, if one circuit of the closing or opening control circuit is damaged, the other circuit can also be used to test the closing and opening.
 
Equipped with linear sensors, rotation sensors, and dedicated fixed multifunctional connectors, easy and simple to install. The length of the linear sensor can be set from 30-1000mm, just equip the sensor, and the instrument does not need to be returned to the factory to change the program.

The host can store 100 sets of current test data, with a real-time clock inside for easy archiving.

Equipped with USB and R232 interfaces, data can be saved to a USB drive and uploaded to a computer for analysis, saving, and printing. The R232 interface can be connected to a computer for online operation (optional function).

The internal anti-interference circuit can meet the reliable use in a 500KV substation.

LCD screen with adjustable contrast.

High speed thermal printer.

Can store 100 sets of measurement data.
