>Suitable for mechanical dynamic characteristics testing of various high voltage circuit breakers within 500KV voltage level
>Can measure actual stroke and custom stroke
>Can achieve single close, single open, close-open, re-close, re-open operations of circuit breakers
>Convenient wiring, simple operation, only one close (open) action is needed to obtain all data of close (open), can choose to save 50 sets of data, provide later query and upload to computer for permanent storage, also can on-site view and print all data and motion curve diagrams
>Built-in clock circuit, can display current year, month, day, hour, minute, second, even if power off, can automatically save setting data and test data
>Built-in delay protection function, after circuit breaker action, can automatically cut off the action power supply, well protecting the circuit breaker equipment and high voltage switch tester
>The instrument has built-in DC power supply, selectable range: 30-270V/10A, no voltage drop at the moment of output of conventional rectifier power supply, very accurate for testing switch action voltage
>Can dynamically analyze the relationship between stroke, speed of circuit breaker within every 1ms time
>Can be configured with upload software, to achieve computer archiving and online viewing, printing.
