Atec Chroma-11022-11025 - Manual

LCR Meter
The Chroma 11022 and 11025 LCR Meters are
passive component testers that can give you
the most cost effective alternative equivalent
to the high priced meters. They are designed
for the demanding applications in production
test, incoming inspection, component design
and evaluation. Programmable test signal level
settings are from10mV to 1V in a step of 10mV,
and the VM/IM signal level monitor functions
allow you to evaluate your devices at the level you
specify. Ten test frequencies of 50Hz, 60Hz, 100Hz,
120Hz, 1kHz, 10kHz, 20kHz, 40kHz, 50kHz, and
100kHz, can be used to evaluate passive compo-
nents and transformers/ LF coils.
The low cost LCR meters on the market have
shortcomings when used for low impedance
components evaluation such as large capacitance
of electrolytic capacitors and low inductance of
coils. As the 11022/11025 equipped with high
resolution (0.01mΩ) in low impedance and high
accuracy (0.3%) till 100mΩ range, it can be used
to evaluate low impedance components to meet
the measurement requirements.
The 11025 LCR Meter can also measure DC resis-
tance, turn ratio and mutual inductance of trans-
former. It is suitable for pulse transformer or LF
coil evaluation. Chroma A110207 Transformer
Test Fixture used with the 11025, can measure
both the primary and the secondary parameters
automatically by changing the internal relays of
11025. So there is no need to change the connec-
tions required for measuring transformer param-
eters. Adjustable internal DC bias current source
can be up to 200mA(constant 25Ω) which is a
standard function, as the right tool for inductance
inspection of telecom transformers and small
power chokes under DC bias current.
The 11022/11025 LCR Meter provides a powerful
combination of features designed to maximize
the productivity in all testing environments. The
measurement speed in the SHORT integration
time mode is 21mS(≧100Hz). Handler interface
and pin-out are compatible with 4263B. GPIB
Interface and IEEE 488 commands are compatible
with 4263B.
In addition, the 11022/11025 have built in a
comparator, 8 bin sorting, trigger delay functions
and handler interface trigger function, which
make them easy for system integration, and
improve the measurement throughput as well as
reliability.
