Introduction
The 8845A and 8846A are 6-1/2 digit, dual-display multimeters designed for bench-top,
field service, and system applications. Their full complement of measurement functions
plus its RS-232, IEEE 488, and Ethernet Remote Interfaces makes these multimeters
ideal candidates for precision manual measurements and use in automated systems. For
portability, these multimeters include a carrying handle that also serves as a bail for
bench top operation.
There are a few feature differences between these two multimeters, and some
specifications are tighter for the 8846A. Features that exist in only one multimeter will be
identified with the addition of “8846A Only” by each feature that is found only in that
model. Separate specification tables are also used to clarify the differences between these
two models.
The following is a list of some of the features and functions:
•
Bright, large-digit, wide-viewing-angle display
•
Dual display for displaying two properties of an input signal (e.g., ac voltage in one
display and frequency in the other).
•
Remote operation via IEEE 488, RS-232, and Ethernet interface.
•
Trigger in and measurement-complete out
•
Front panel USB port for optional memory (8846A Only)
•
6-1/2 digit resolution
•
Half-rack width
•
True rms ac
•
2 and 4-wire resistance measurements
•
Extended 10

ranges (8846A Only)
•
Frequency measurements to 300 kHz (8846A to 1 MHz)
•
Capacitance measurements (8846A Only)
•
Temperature measurement (8846A Only)
•
10 A current capability
•
Decibels (dB and dBm) with variable reference impedance and audio power
measurement capability
•
Input terminals on both front and rear panels of the meter
•
Closed-case calibration (no internal calibration adjustments)
Manual Set
The manual set for these multimeters consists of a Users Manual and Programmers
Manual on a CD ROM. The Users Manual contains information on specifications, setup,
and operating from the front panel. The Programmers Manual covers operating the Meter
from a PC or controller.
