Use the built-in linear and logarithmic sweep
function, supporting up to 201 sweep points, to
conveniently display, analyze and store
primary and secondary parameters of a
component. Sweep test frequency, AC source
voltage and current levels, DC bias source
voltage and current levels. A delay can be
programmed after each sweep point. The list
sweep can be triggered internally, manually or
externally and executed in sequence or step
mode.
Programmable List sweep
Quickly sort components using the instrument’s 9
primary BINs, a secondary BIN and
out-of-specification BIN. The results can be
displayed in a table on-screen or output via
the handler interface. High and low limits for
each bin can be set up in absolute, tolerance or
sequential mode with Pass/Fail indicator.
Bin sorting function
Integrate your LCR meter into an automated test
system and control it from a PC using SCPI
commands via the RS232, USB, LAN, or
GPIB (895 only) interface.
Remote PC control
Flexible test accessories
Standard accessories shipped with each unit are Kelvin clip test leads for 4-wire measurements, a test fixture, and shorting bar. The optional transformer test
fixture allows users to measure transformer parameters.

Transformer test xture (TL89T1)
Test xture (TL89F2)
Shorting bar (TLBSB)

Using optional test fixture TL89T1, the 894
and 895 can test the primary and secondary
inductance L1, L2, turn ratio (N, 1/N), mutual
inductance (M), and primary and secondary
direct-current resistance (R2) of a transformer
directly. Additionally, the two common
transformer parameters winding equivalent
capacitance C
o
and leakage inductance L
k
can
be characterized indirectly.
