[1] Visual Connection Management Terminals. The appropriate terminals light up in green when E
is pushed, whether in STANDBY or OPERATE. The terminals offer visual guidance for cable
connections for specific functions, protect the user by indicating which terminals are active, and
protecting the calibrator from damage from incorrect connections.

Connection points for ac and dc current and voltage output, and resistance. The
function of each OUTPUT binding post is defined below:
LO
The common binding post for all output functions including 5725A amplified voltage
output, but not Option 5730A/03 or 5730/05 Wideband AC or other auxiliary
amplifier output.
HI
The active binding post for all output functions including 5725A amplified voltage

output, but not Option 5730A/03 or 5730/05 Wideband AC or other auxiliary
amplifier output.
AUX CURRENT OUTPUT
An optional active binding post for current. It is convenient to use the AUX
CURRENT OUTPUT binding post when calibrating a UUT with a separate current
input terminal. Refer to "Connect the Calibrator to the UUT" in Chapter 4 for
instructions for use of this binding post.
The SENSE binding post is used with resistance and voltage functions for sensing
at the UUT after the external sense has been selected by the touch of External
Sense or by remote command.
External sensing should be used in the dc voltage function when the UUT draws
enough current to produce a significant voltage drop in the cables, and in the
resistance function when the UUT has a four-wire ohms input and the Calibrator is
set to 100 kΩ or less. External sensing can also be used in the two-wire ohms
function to allow the two-wire compensation circuitry to the UUT terminals. Refer to
"When to use External Sensing," "Four-Wire Vs. Two-Wire Resistance
Connections," and "Cable Connection Instructions" in Chapter 4 for external
sensing instructions and illustrations of SENSE connections.
