Series 2600A System SourceMeter® Instruments Reference Manual
Input/output connectors
The Keithley Instruments Series 2600A System SourceMeter
®
Models 2601A, 2602A, 2611A, and
2612A use screw connectors for input and output connections to devices under test (DUTs). The
Model 2602A/2612A uses two connectors as shown in
unit (SMU) channel). The Model 2601A/2611A has only one connector for a single SMU. Models
2635A and 2636A use triax connectors as shown in
A connector 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
) to 12 AWG
(2.5mm
2
) conductors.
After making the wire connections from a connector to a DUT, reinstall the connector onto the rear
panel and tighten the two captive screws.
WARNING
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 2600A
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 instrument 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
later in this section for details
on floating the SMUs.
The input/output connectors of the SourceMeter instruments are
rated for connection to circuits rated Installation Category I only,
with transients rated less than 1500V peak. Do not connect the
Series 2600A terminals to CAT II, CAT III, or CAT IV circuits.
Connections of the 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
instrument, when connecting to a source with a greater current
capability than the Series 2600A, a fuse should be provided in-line
with the Series 2600A input/output connectors rated no more than
3A.
