Start-up (power-on) configuration
You can specify the 2606B start-up (power-on) configuration. Use the
setup.poweron
attribute to
select which setup to return to upon power-up. To set the
setup.poweron
configuration attribute:
setup.poweron =
n
-- Select power-on setup.

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 or 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. 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 2606B System SourceMeter
®
instrument uses screw terminal connectors for
input and output connections to devices under test (DUTs).
You can remove a screw terminal connector 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
) to 12 AWG
(2.5 mm
2
) conductors.
Basic connection sequence:
1. With the output off and the connector uninstalled from the 2606B 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.
