1. A high brightness, high definition and high resolution TFT color LCD screen shows clearly and beautifully, with large information content and rich content, and the screen shows all the parameters measured on the site.
2. Single and three phase voltage, current, power, phase, active and reactive power factor, frequency and other parameters can be in real time measured.
3. The energy meter and terminal errors can be calibrated, and single-phase and three-phase electronic induction active and reactive energy meters can be inspected.
4. The pulse input modes include manual input, photoelectric input and electric pulse input threeways.
5. 100A, 500A and 1000A clamp meters are optional, and the transformation ratio of low voltage current transformer is directly measured; it is easy to find the open circuit and poor contact in the CT secondary circuit, internal turn-to-turn short circuit of CT and whether the transformation ratio on the CT nameplate is consistent with the actual transformation ratio of CT.
6. It can measure the content of the 2nd ~ 51st harmonics of single and three phase voltage and current.
7. The waveforms of A, B and C-phase voltage and current can be measured.
8. A wide range of working power supply is AC57 ~ 450V; the test line, adapter and battery power supply can be chosen respectively, and online charging is available.
9. With a large capacity memory card, it can store field calibration data of more than 10000 groups of energy meters, and U disk storage is supported; such data can be permanently saved upon non-human deletion.
10. The ground software system can connect with the marketing system, with a friendly interface, easy operation, complete functions and easy to upgrade; the test data cannot be changed, and the software has the functions such as statistics, query, and printing; the test report format can be set according to the requirements of users.
11. Read the record data of multi-function electronic energy meter including the reading data, pressure loss records and clock.
12. The calibrator has the function of clamp transformer self-correction and can not need to be returned to factory for calibration after replacing the clamp meter.
