Functions

circuit breaker tester

1) Measurement of closing time, opening time, time spread between poles, time spread between units of one pole, bounces etc.

2) Measurement of closing speed, opening speed and average speed.

3) Measurement of clearance between open contacts, over travel, overshoot travel and total travel.

4) Measurement of closing coil current time curve, opening coil current time curve and the maximum coil current

5) Test travel time curve, speed time curve and acceleration time curve

6) Measurement of pre-insertion resistance value and pre-insertion ion time.

7) Test contact resistance

8) Measurement of dynamic resistance time curve and length for arcing contacts

10) Vibration test, including vibration fingerprint curve acquisition, management, and vibration fingerprint curve automatic matching.

11) CO-t1-CO,O-t-CO-t1-CO,CO rated operating sequence verification test.

12) Drawing Envelopes for reference travel curve and compare travel curve with envelopes

13) Mechanical travel curve automatic compare with saved travel curve

14) Measurement of CO time (close-open time) and OC time (Opening-Closing time)

15) Graphite contact closing time, opening time, dynamic resistance curve measurement

16) Zoom, editors, statistics and analysis for measurement curves.

17)12.1-inch touch screen for control and data input

18) Built-in micro printer for test result printout.

18) Generate WORD format test report automatically (all reports and data can be exported through Flash disk).
