891

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. 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.

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. Linear sweep function, Logarithmic sweep function, and Linear & Logarithmic sweep function table 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. Built-in web server interface 3 Display options Users have the option to display up to 4 digits resolution on primary and secondary measurements in decimal or scientific notation. Large display mode is also available for easy viewing from a distance. Large display mode Remote PC control Integrate your LCR meter into an automated test system and control it from a PC using SCPI commands via the standard USB, GPIB, or LAN interface.
