4.7.9 Saving Transient List Programs
When the AC source is turned off, the transient list that was programmed is not automatically retained
Thus, if you turn the unit off, you will loose your programmed transient list. However, transient
programs may be saved in nonvolatile memory for later recall. This allows multiple transient list
programs to be recalled quickly without the need to enter all parameters each time. Transient lists are
setup in any of the ava
.
ilable setup registers.

er-on Initialization Values
The power source is shipped with default factory settings when the unit is powered up. The factory
settings are:
Parameter Factory default setting
Voltage 0.0 Volt
Voltage Range 150 Volt Range
Frequency 60 Hz
Current limit Maximum available current for selected V Range.
Output state OFF
Local / Remote State Local. Front panel unlocked.
Table 4-3: Factory Default Power on Settings
It is possible to change the power on initialization values in one of two ways:
1. Using the IEEE-488, LAN or USB bus interface.
2. Using the front panel.
To change the power on initialization values from the front panel, proceed as follows:
1. Set the AC power source output parameters from the front panel as you want to power up the
unit.
2. Save this setting to setup register 0 from the REGISTERS menu.
3. Select the CONFIGURATION menu and move to the POWER ON field.
4. Change the POWER ON field to REG0.
5. This will recall the settings contained in register 0 at power up.

4.9 Remote Inhibit Function
The remote inhibit input available on the DB9 connec
output of the AC source.
tor at the rear panel can be used to disable the
This input takes either a low level TTL signal or a contact closure. The mode
of operation can be programmed over the remote control interface using the OUTP:RI:MODE
command. See 6005-961 programming manual for details.
The following modes are supported.
MODE OPERATION
LATCHING A TTL low at the RI input latches the output in the
protection shutdown state, which can only be cleared
by an OUTPut:PROTection:CLEar command or by
manually resetting the output.
LIVE The output state follows the state of the RI input. A TTL
low at the RI input turns the output off; a TTL high
turns the output on. This mode is equivalent to using
the Output On/Off button on the front panel.
Default mode. This mode is active at power up.
OFF The instrument ignores the RI input.
Table 4-4: Remote Inhibit Modes.
The RI output state is saved as part of an instrument setup using the REGISTERS menu. It can be
made part of the power on setting if needed. The default state is LIVE.
