WARNING
USE PROPER FUSES. For continued protection against fire
hazard, replace the line fuse(s) only with fuses of the same
current rating and type (such as normal blow, time delay, etc.).
Do not use repaired fuses or short-circuited fuseholders.
CAUTION
Static electricity is a major cause of component failure. To prevent
damage to the electrical components in the multimeter, observe
anti-static techniques whenever working on the multimeter.
Multimeter
Description
The E1411 multimeter is an "instrument" in the slots of a VXIbus
mainframe. As such, it is assigned an error queue, input and output buffers,
status registers, and is allocated a portion of mainframe memory for reading
storage.
NOTE
Instruments are based on the logical addresses of the plug-in modules. See
the Agilent 75000 Series C Installation and Getting Started Guide to set the
addresses to create an instrument.
The instrument may consist of a multimeter only (stand-alone operation), or
can include relay or FET multiplexers (scanning multimeter operation). The
instrument is operated from a computer using Standard Commands for
Programmable Instruments (SCPI) language.
In stand-alone operation, input signals are connected to the multimeter’s
external (faceplate) terminals. In scanning multimeter operation, input
signals are connected to the multiplexer channels. The multimeter is linked
to relay multiplexers via an analog bus cable. The multimeter is linked to
FET multiplexers via an analog bus cable and a digital bus cable.

Specifications
Multimeter specifications are listed in Appendix A of the E1326A/E1411A
User’s Manual or the E1326B/E1411B User’s Manual. These specifications
are the performance standards or limits against which the instrument may be
tested.
