Add to Cart
ZX-CHA Capacitance and inductance tester (with imported clamp) adopts bridge circuit structure, with standard capacitor and tested capacitor as two arms of bridge circuit. When the capacitance value of the capacitor is measured, the test voltage is applied to the standard capacitor and the tested capacitor at the same time. The processor collects the current signal flowing through the sensor and processes to obtain the capacitance value of the tested capacitor.
Features
1. The instrument can measure the single capacitance of a group of parallel capacitors without disconnecting the wire (both single-phase capacitance and three-phase capacitance can be measured). At the same time, the instrument can also measure the inductance of various reactors, and can also be used as the power frequency current tester is used, one machine and three uses, to meet a variety of uses on site.
2. During measurement, the instrument can display the measured capacitance or inductance value, as well as the measured voltage, current, capacity, power, frequency, impedance, phase angle and other data, so as to better analyze the quality of the test sample.
3. The instrument adopts a 240 × 128 large screen with backlit LCD display, which can be clearly observed during the day and night, with English menu prompts and easy operation.
4. The instrument has a built-in large-capacity non-volatile memory, which can store 50 sets of measurement data.
5. The instrument has a built-in high-precision real-time clock function, which can calibrate the date and time.
6. The instrument comes with a high-speed micro thermal printer, which can print measurement and historical data.
7. Instrument test power supply over-current protection function, short circuit of power supply output will not damage the instrument.
8. The instrument also has an automatic measurement function, which can automatically identify the type of sample (capacitance, inductance, resistance).
