The MT4080A/MT4080D LCR Meter is the first handheld meter of this type on the Market, with a wide range of test frequencies up to 10KHz (MT4080D) or 100KHz (MT4080A), and many measurement parameters including Z, L, C,DCR, ESR, D, Q, and q as well. The MT4080A/MT4080D is design for both component evaluation on the production line and fundamental impedance testing for bench-top applications. With a build-in direct test fixture you can test the lead components very easily. The 4-wire test clip can give a convenient connection to larger components and assemblies ith the accuracy of 4-wire testing. The LCR meter offers fast,reliable,and versatile testing at low cost.Furthermore, the optional RS232C interface (IrDA) is an attractive, cost-effective solution for quality assurance and incoming inspection operations,making the MT4080A/MT4080D is the most advanced handheld LCR meter available on the market today.
ESR measurement
In today's switching mode power supply design, higher frequency is reached everyday to take advantage of the size and output power barrier. To ensure the performance of the circuit, the Equivalent Serial Resistance (ESR) in a capacitor is the key element determining efficiency and performance. With mt4080a/Mt4080D the user can quickly check the ESR of a capacitor up to 100KHz or 10KHz without hesitation.
Built-in infrared Port
MT4080A/MT4080D comes with a bulit-in infrared port to allow communication with a personal computer.With the fully Remote Control Command (RCC) support,both units are able to act as an automatic LCR testing system-this is especially applicable in automatic Q.A and I.Q.C testing. The user is able to control the measurements and get the measured values through the IrDA port.Remote-Binning feature,easily sorting the components ,is combined with remote-binning software and infrared port.
SMD test probe(optional)
Surface_mount components are usually tiny and have no wire leads, making it more difficult to test surface_mount devices than conventional components. The TL08 SMD test probe gives users an easy way to conduct SMD component testing.The uniquely designed SMD test probe can also be used to test conventional components if the wire leads are too short to insert into the test terminals.
Open and short calibration
In the world of LCR meters,open and short calibrations are important procedures before making any measurements, especially when user changes the testing frequency and level. Therefore, very fast open and short calibrations are the key factors to the user. Within just 10 seconds, the user can perform open or short calibrations at any frequency and level that s/he desires.
Transfromer measurement
To qualify xDSL transformers, you can measure the primary inductance or coupling capacitance at 10KHz,and leakate inductance at 100KHz with lower test voltage. You can also measure the DC-resistance of primary and secondary with the standard DCR function. |
