Three phase capacitance inductance tester DYDR-III

1、 Product characteristics

1. Internal battery, automatic digital synthesis generates three-phase high-power test power supply, which can be used without external power supply;

2. The instrument can measure the single single-phase capacitance of a group of parallel capacitors and simultaneously measure the three-phase capacitance of various connection types without removing wires;

3. Three phases can be measured simultaneously or three parallel capacitors can be measured simultaneously;

4. The instrument can measure the inductance of various reactors;

5. The instrument can measure the amplitude of power frequency current and the content of 2-32 harmonics in the current;

6. The instrument can display the voltage, current, power, phase angle, impedance and other data measured in the process of measuring capacitors or reactors, so as to better analyze the problem;

7. The instrument has two current sampling methods: measurement without clamp meter (high precision, preferred measurement method) and measurement with clamp meter (the instrument is equipped with a clamp meter with a diameter of 50mm, which is used to measure the capacitance and capacitance of any capacitor of the capacitor bank connected in parallel).

8. Instrument test power overcurrent protection function: short circuit of power output will not damage the instrument.

9. The instrument adopts 800 × 480 large screen high brightness true color LCD, which can be clearly displayed in the sun;

10. Graphical menu, full Chinese operation prompt, friendly interface and easy operation;

11. The conductive silicone touch button makes the operation easier and the button life longer.

12. The built-in large capacity nonvolatile memory of the instrument can store 200 groups of measurement data;

13. The built-in high-precision real-time clock function of the instrument: date and time can be calibrated;

14. The instrument has its own high-speed micro thermal printer: the user can print the test data through the micro printer at any time;
