Digital I/O port
A digital input/output port that detects and outputs digital signals. The
port provides six digital I/O lines. Each output is set high (+5 V) or low
(0 V) and can read high or low logic levels. Each digital I/O line is an
open-drain signal.
USB Type B port
USB Type B connection for communication, control, and data
transfer.
LAN STATUS
LED indicator
Illuminates when the instrument is connected to a local area network
(LAN).
LAN port
Supports full connectivity on a 10 Mbps or 100 Mbps network. The
DMM7512 is a version 1.5 LXI Device Specification 2016 instrument
that supports TCP/IP and complies with IEEE Std 802.3 (ethernet
LAN). See
Setting up remote communications
(on page 7).

INPUT and
SENSE terminals
Use the INPUT HI and INPUT LO terminals for all
measurements except current. For current
measurements, use the AMPS connection with the
INPUT LO terminal.
Use the SENSE HI and SENSE LO terminals and the
INPUT terminals with the 4-wire resistance, 3-wire
and 4-wire RTD temperature, and DC voltage ratio
functions.
AMPS connection
3 A, 250 V current connector for DC current and digitize DC current
10 µA to 3 A ranges.
