The main functions and characteristics of capacitive and inductance measuring instrument
Power output: The power output adopts PID regulation algorithm for constant current and voltage limiting output, which strengthens the measurement accuracy and stability, and the output short circuit will not damage the instrument.
Single-phase test function: the instrument can measure single-phase capacitors, reactors, resistors, while single-phase measurement can also choose automatic test, by the instrument automatically judge the type of test.
Three-phase capacitance test function: The instrument has three-phase power output and interface, can be three-phase Y-type connection capacitor, three-phase Yn type connection capacitor, three-phase △ type connection capacitor, three-phase III type connection capacitor for a one-time connection, you can complete the three-phase capacitance test, and the separate phase capacitance test calculation, simple and convenient, Greatly improve the work efficiency of field users.
Capacitance measurement: accurately set the rated frequency and rated voltage of the capacitor test, and the instrument can automatically calculate the compensation capacity of the capacitor, reducing the calculation amount of on-site personnel.
Test reactance measurement: The instrument can automatically calculate the capacitive reactance, inductive reactance and impedance of the test according to the measurement results, which is convenient for further data analysis on site.
Current test function: The instrument clamp current transformer can be used for current detection alone, which can detect the basic wave RMS value, total harmonic distortion, signal frequency and the content rate of the third, fifth, seventh and ninth harmonics of the current signal, so as to carry out simple power quality analysis of the current signal.
The instrument adopts large screen LCD display, using Chinese menu, Chinese prompt, simple operation.
No power off clock and date display; Data storage is divided into local storage and flash disk storage, in which the local storage can store 200 test data, and the local storage can be transferred to the flash disk; The flash disk storage data format is Word format, which can be edited and printed directly on the computer.
Thermal printer printing function, fast, silent.
Human-computer interface is more friendly: the status bar at the top of the screen displays the flash drive insertion status, test status, storage status, etc., when the unconnected device is operated, the corresponding unconnected prompt information is displayed.
Small size, light weight, easy to carry and use.
