TH2825A high-speed LCR meter is new-generation component
parameter measurement instrument. It offers high measurement
speed up to 20times/second, 10 frequencies from 40Hz to
100kHz, programmable signal level from 0.01V to 1.0V with step
of 10mV, 5-digit resolution, multi source resistance selections, and
strong measurement functions. So it is suitable for quality control
on production line, incoming inspection, and component design.


High measurement speed

This instrument, using the most advanced technology in the
field, has the strong measurement function which is compatible
with advanced products in the world. It provides incomparable
measurement speed up to 20 times/second, which solves the
problem of slow measurement speed at low frequency. So it
is ideal instrument to perform high-speed measurement for
electrolytic capacitor, ceramic capacitor, and transformer.


Multi selectable signal source impedance modes

Different LCR meters get different measurement results
because of different impedances. TH2825/TH2825A provides 5
selectable impedance modes to meet different needs, to ensure
the consistency of measurement results between different meters.
Constant-voltage mode suitable for measurement of multilayer
ceramic capacitor(MLCC)
Constant-voltage mode suitable for measurement
of multilayer ceramic capacitor (MLCC)


MLCC is rather sensitive to signal test level. And TH2825/
TH2825A can measure large-amount MLCC with constant highlevel
signal. It is allowed to measure MLCC of 30μF at constant
1kHz/1Vrms, and MLCC pf 300μF at constant 100Hz/1Vrms.
Powerful transformer measurement function


TH2825A has the function of measuring transformer. Using
special transformer test fixture, turns ratio (N, 1/N), mutual
inductance (M), primary and secondary inductances (LA, LB),
primary and secondary DC resistances (DCR2) can be measured
without changing test cable mode. With adjustable DC bias
current up to 200mA (TH2825/TH2825A both have), the meter can
conveniently measure communication transformer and choke with
small power.
Interface being compatible with famous meters


HANDLER, GPIB interfaces and GPIB interface command
are completely compatible with Agilent 4263B, which help build
conversion with 4263B.
