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. |
