NOTE.
All measurements are at the terminals. If the wires used to connect the channels together are too small, too long,
or improperly tightened, accuracy of measurements will be adversely affected.

Recall the Power Supply ON/OFF Output State at Power On
This parameter determines the On or Off output state after the power supply is powered on. If you select
On
, the power
supply will restore the state of the output to that which was in use before the power was last turned off. If the output was
turned
On
when the power supply is turned off or loses power then the output will return to the
On
state when the power
supply is turned back on or power is restored.
Off
will disable this function and the output channel will always be set
to
Off
after the power supply is powered on.

Recall the Power Supply Operating Parameters at Power On
This parameter determines whether the power supply saves its most recent settings, such as voltage and current, and
restores these settings at power on. If you set this parameter to
Off
then the power supply returns to the default settings
at power on. If you select
On
, the power supply will restore the state to that which was in use before the power was
last turned off.
