Five Advantages Of Products

  • Digital bridge is suitable for measuring the impedance parameters of capacitors, inductors, cores, resistors, transformers, chip components and network components, etc. It can also be used for the impedance evaluation of printed circuit boards, relays, switches, cables, batteries, etc. Digital bridge is a common measuring instrument used by electronic engineers.

  • Digital bridge A bridge using digital technology to measure impedance parameters. Digital technology is to transform the traditional analog quantity into digital quantity, and then carry out digital operation, transmission and processing.

  • The digital bridge is measured at a frequency of about 100 KHZ. The basic measurement error is 0.02%, generally around 0.1%.

  • Digital bridge can provide stable 6-bit test resolution, 10Hz-300kHz frequency range, 0.01V-2.0V programmable signal level, up to 30 times/SEC measurement speed, 9 level fine range, constant 30ω or 100Ω source resistance and flexible human operation mode, can meet the quality assurance of production line, receiving inspection and laboratory.

  • Digital bridge with English and Chinese operation interface, simple operation, some models can provide data recording function.

Product Details

Brief introduction of digital bridge:

   Digital bridge, also known as LCR tester, LCR bridge, LCR Meter, LCR meter, etc., is used to detect passive components: capacitors, inductors, magnetic cores, resistors, piezoelectric devices, transformers, chipsets; Balancing devices: impedance parameter evaluation of common-mode filters, balancing capacitors, integrated resistance voltage dividers and network components; Other components: Impedance evaluation of printed circuit boards, relays, switches, cables, batteries, etc. Digital bridge is a commonly used measuring instrument for electronic engineers, which is widely used in incoming material inspection, PCB production, failure analysis and so on.


   Digital bridge can provide stable 6-bit test resolution, 10Hz-300kHz frequency range, 0.01V-2.0V programmable signal level, up to 30 times/SEC measurement speed, 9 level fine range, constant 30ω or 100Ω source resistance and flexible human operation mode, can meet the quality assurance of production line, receiving inspection and laboratory.

Working principle of digital bridge:

The earliest impedance measurement of digital bridge is the bridge method. With the development of modern analog and digital technology, the modern impedance measurement mostly uses the automatic balanced bridge method, which can not only measure the impedance, but also directly display the value parameters of L-Q, C-D, R-D and Z-Q inductors and capacitors.

The use of digital bridge:

    Digital bridge test inductance and capacitance, the measurement steps are as follows:

   

1. Set the test frequency

2. Test the voltage or current level

3. Select test parameters, such as Z, Q, LS, LP, CS, CP, D, etc

4, instrument calibration, calibration is mainly open and short circuit calibration.

5. Select the test fixture

6. Fixture compensation

7. Put the DUT on the fixture to start the test.
