How much do you know about the common sense of automatic capacitance and inductance tester?


Darui Electric recommends for you





Automatic capacitance and inductance tester adopts a high-precision 50mm clamp-type CT for current detection, combined with a digitally isolated voltage detection circuit, featuring stable performance and high measurement accuracy. The instrument uses a backlit large-screen LCD display, which can be clearly observed both day and night. It uses a Chinese menu and is very simple to operate. The instrument can store 128 sets of measurement data and comes with a built-in thermal printer to print measurement data. Its main functions are to measure the per-phase capacitance value and total capacitance value of compensation capacitors, the resistive component of the test object, dielectric loss angle, loss factor, reactive power, and active power. It adopts a new generation of high-speed hybrid microprocessors and is highly integrated.

　　Automatic capacitance and inductance tester related introduction:


　　1. Testing without disconnecting wires: The instrument is equipped with a large-current high-precision current clamp, allowing on-site measurement of capacitors without removing connecting wires, simplifying the test process, effectively improving work efficiency, and avoiding damage to power equipment;


　　2. Highly intelligent: After completing three-phase testing, it automatically calculates parameters such as per-phase capacitance value, total capacitance value, and reactive power, which is simple and intuitive, reducing the burden on test personnel;


　　3. Four-terminal measurement: Adopts four-terminal measurement technology, ensuring accurate measurement and good test repeatability;


　　4. Automatic compensation: Current is automatically compensated in segments, making the current full-scale linear, improving the instrument's measurement accuracy;


　　5. Storage function: The instrument can store up to 400 data records and has a historical data query function;


　　6. USB communication: USB communication function, combined with PC software, enables data analysis, saving, printing, and generation of complete test reports, facilitating centralized data management;


　　7. Large touch screen: 7-inch large true-color touch LCD display, Chinese display, intuitive interface, and simple operation;


　　8. Temperature monitoring: Monitors ambient temperature, facilitating the recording of capacitance values of capacitors at different temperatures;


　　Automatic capacitance and inductance tester testing precautions:


　　1. Before use, the grounding terminal on the panel of the capacitance and inductance tester must be grounded to avoid the risk of electric shock!


　　2. During measurement, the test voltage output switch must be set to the "ON" position.


　　3. To obtain the correct capacitance value, the same voltage value as on the capacitor nameplate must be set before measurement.


　　4. If accuracy is suspected to be problematic, use the reference capacitor provided with the capacitance and inductance tester for checking.


　　5. When measuring small capacitance and large inductance, the position of the clamp meter affects the measurement value. Please place the clamp meter in the center of the tested wire and keep the jaws fully closed.
