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.
1. To turn your instrument on, press the front panel
POWER
switch to place it in the on (I) position.
2. To turn your instrument off, press the front panel
POWER
switch to place it in the off (O) position.
Placing the 2606B in standby
Hazardous voltages may be present on all output and guard terminals. To prevent electrical
shock that could cause injury or death, never make or break connections to the 2606B while
the instrument is powered on. Turn off the equipment from the front panel or disconnect the
main power cord from the rear of the 2606B before handling cables. Putting the equipment
into standby does not guarantee that the outputs are powered off if a hardware or software
fault occurs.
When the instrument is on, you can place the output in an active output state (output on) or a standby
mode (output off).
To place the output in standby, send the command:
smu
X
.source.output = 0
Even though the instrument is placed in standby, the output may not be actually off.
Warmup period
The 2606B must be turned on and allowed to warm up for at least two hours to achieve rated
accuracies.
