DUT test connections

Hazardous voltages may be present on all output and guard terminals. To prevent electrical
shock that could cause injury or death, remove power from the instrument or test system and
discharge any energy storage components (for example, capacitors or cables) before
changing any connections that might allow contact with an uninsulated conductor.
On some sensitive or easily damaged devices under test (DUTs), the instrument power-up and
power-down sequence can apply transient signals to the DUT that may affect or damage it. When
testing this type of DUT, do not make final connections to it until the instrument has completed its
power-up sequence and is in a known operating state.
When testing this type of DUT, disconnect it from the instrument before turning the instrument off.
To prevent any human contact with a live conductor, connections to the DUT must be fully insulated
and the final connections to the DUT must only use safety-rated safety jack socket connectors that
do not allow bodily contact.

Input/output connectors

The Keithley Instruments Series 2600B System SourceMeter
connectors or triaxial connectors for input and output connections to devices under test (DUTs). The
Models 2601B, 2602B, 2604B, 2611B, 2612B, and 2614B use screw terminal connectors; Models
2634B, 2635B, and 2636B use triaxial connectors.
A screw terminal connector can be removed from the rear panel by loosening the two captive
retaining screws and pulling it off the rear panel. Each screw in the terminal connector cable
assembly (used with the SMU connector) can accommodate from 24 AWG (0.2 mm
2
(2.5 mm ) conductors.
Basic connection sequence:
1. With the output off and the connector uninstalled from the Series 2600B rear panel, make the
wire connections from a connector to the DUT.
2. Reinstall the connector onto the rear panel.
3. If using a screw terminal connector, tighten the two captive screws.
