I. Introduction
The kit can be used for testing various of electricity parameters at work site and inspecting electricity theft. Also this kit can test energy error at fast speed and have function of checking meter constant. In a word, this kit is special design for single phase electricity-use inspect.
II. Features & Functions
1. Parameter test
Can test voltage, current, frequency, phase, active power, reactive power, power factor, etc on-site.
2. Energy error test
Can test energy error by various methods including moving watt-second method (current method), stable watt-second method, optical sensor standard meter method and manual switch standard meter method.
3. Check constantCan check the accuracy of meter constant by three methods including moving wattsecond, stable wattsecond, and standard meter method.4. Data memory functionCan freeze current test data when testing in order to be easy to record. User can also take current test data as default value of error test.5. Over-limit protection of test signal
The kit will automatically go into overlimit protection with audible alarm and indication signal when test signal is over limit.6. CommunicationCommunication with PC by USB, also can upload saved test datum and user information to PC, and reserve communication agreement for user.Note: please don’t perform communication when test to avoid damage of kit.
7. Low consumption designAdopting low consumption design with longlife battery. The user can have continuous working for 25 hours by two pc battery.
