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.
