SENSE Binding Posts
Used in the resistance and voltage functions for
sensing at the UUT after you have selected
external sense by toggling the X key on, 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 the connection diagrams for examples of usage.
OUTPUT Binding Posts
Provide connection points for ac and dc current
and voltage output, as well as for resistance. The
function of each OUTPUT binding post is defined
below:
LO
HI
AUX
CURRENT
OUTPUT
The common binding post for all
output functions including Calibrator
amplified voltage output, but not for
Option -03 Wideband AC or auxiliary
amplifier output.
The active binding post for all output
functions, including 5725A amplified
voltage output; does not include
Option -03 Wideband AC or auxiliary
amplifier output.
An optional active binding post for
current. This output is convenient for
calibrating UUTs that have a
separate current input terminal.
