Data Sheet
Bench LCR Meter
Model 891
The 891 is a compact, precise, and versatile LCR
meter capable of measuring inductors, capacitors,
and resistors at DC or from 20 Hz to 300 kHz.
The instrument’s 2U half-rack form factor is
suitable for the bench or rack mount installation.
A large color display with all important parameters
and measurements visible on one screen makes
this meter easy to operate.
Model 891
Best accuracy 0.05%
Test frequency 20 Hz - 300 kHz
Test levels 0.5 Vrms and 1 Vrms selectable
Measurement parameters
The instrument’s convenient bin sorting function
enables quick sorting of components in different
bins defined by the user. A linear and logarithmic
sweep function is also provided to characterize
components over any range of frequencies from
20 Hz to 300 kHz.
Standard USB, GPIB, and LAN interfaces
enhance your productivity by providing remote
control capabilities to perform daily operations
in production, quality control, and laboratory
environments.

Bin comparator sorting function
Quickly sort components with the instrument’s
9 primary BINs, 1 secondary BIN, and 1
out-of-spec BIN. The results can be displayed
on a table or histogram and saved to a USB flash
drive. High and low limits for each bin can be set
up in absolute or tolerance mode with Pass/Fail
beep.
Histogram display, Table display, and Bin display
Linear and logarithmic sweep function
Characterize components up to 300 kHz using a
300-point linear or logarithmic sweep. Measured
values for each frequency point can be read
directly on the display. Sweep results can be
displayed on a graph or table and then saved to
a USB flash drive or read out through the remote
interface.
Built-in web server and LAN interface
Configure and control basic instrument settings
and take measurements from a remote computer
using a web browser. The 891 can also be
controlled with SCPI commands using a socket
or Telnet connection via the LAN interface.
