Product Description
Three-phase Energy Meter Field Calibrator Introduction
Three-phase energy meter field calibrator is an advantageous product among electric energy metering series products of the company, and is integrated with energy meter calibrator and low voltage metering device, with energy meter error calibration, error wiring judgment, measurement of transformation ratio, meter reading, harmonic measurement and other functions.
Basic Functions
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 three ways.
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.
Features of new functions:
1. Clock error calibration;
2. Broadcasting timing or command timing of the energy meter can be done (it will be subject to the calibrator time);
3. The rate and time period of the energy meter, demand register and others, and demand value error can be read and set.
4. With the function of small current detection, it is convenient for initial installation and no-load line inspection.
5. Support for bar codes and 2D code scanning input, and an external barcode scanner (USB or wireless way) can read the meter asset number and seal number, etc., convenient for field entry;(optional).
6. With bluetooth, WIFI and GPS interface, it can transmit data to mobile terminals and has the
functions of interaction and extension (optional).

Warning:
As this instrument belongs to electric working equipment, for the sake of your safety, please abide by the national regulations on production safety, and operate strictly according to the field calibration procedures of electric power metering devices.
Notes:
Do not clip the pulse line clip onto the voltage terminal of the energy meter; please do not insert the voltage terminal line into the current terminal;
Do not insert the current terminal into the voltage terminal;Make a right choice of the work power supply (Note: the working voltage range of switching power supply is AC57.7 V ~ 440 V);
Choose the current range correctly, and the current range generally does not exceed 200% of the rating;
Each clamp meter has positive and negative ends: "+" end is the current input, and "-" end is the current output; please do not connect them reversely;
The clamp meter's color represents a different phase: yellow - A phase, green - B phase and red - C phase;
Do not mix different phases of clamp meter, or else it could affect the accuracy of measurement;
At the time of three-phase three-wire measurement, please do not connect B phase voltage line and current line to the instrument, lest affect the accuracy of measurement.
This instrument has a built-in power supply, which can supply power from the voltage terminal; It is used on the calibration console; please select the instrument's battery or external power supply, lest affect the voltage output of the calibration console.
