Input/Output Connectors - Keithley 2601 Reference Manual

Section 3: DUT Test Connections

Input/output connectors

The Keithley Instruments Series 2600 System SourceMeter
use screw connectors for input and output connections to DUTs (devices under test). The Model
2602/2612 uses two connectors as shown in
channel). The Model 2601/2611 has only one connector for a single SMU. Models 2635 and 2636
use triax connectors as shown in
A connectors can be removed from the rear panel by loosening the two captive retaining screws
and pulling it off the rear panel. Each screw can accommodate from 24 AWG (0.2mm
(2.5mm
After making the wire connections from a connector to a DUT, reinstall the connector onto the rear
panel and tighten the two captive screws.

) conductors.
Hazardous voltages may be present on the output and guard
terminals. To prevent electrical shock that could cause injury or
death, NEVER make or break connections to the Series 2600 while
the output is on. Power off the equipment from the front panel or
disconnect the main power cord from the rear of the SourceMeter
before handling cables connected to the outputs. Putting the
equipment into standby does not guarantee the outputs are not
powered if a hardware or software fault occurs.
Maximum floating (common mode) voltage for a SMU is 250V.
Exceeding this level could damage the instrument and create a
shock hazard. See
on floating the SMUs.
The input/output connectors of the SourceMeters are rated for
connection to circuits rated Installation Category I only, with
transients rated less than 1500V peak. Do not connect the
SourceMeter terminals to CAT II, CAT III, or CAT IV circuits.
Connections of the SourceMeter input/output connectors to
circuits higher than CAT I can cause damage to the equipment or
expose the operator to hazardous voltages.
To prevent electric shock and/or damage to the SourceMeter, when
connecting to a source with a greater current capability than the
Series 2600, a fuse should be provided in-line with the SourceMeter
input/output connectors rated no more than 3A.
