– Constant voltage (CV) or constant current (CC) operation
– Overvoltage protection (OVP)
– Five storage locations (1 to 5) for user-defined operating states
– Automatic turn-on self-test
– Remote sense at rear panel terminals
– User calibration from the front panel or over the remote interfaces
Front panel operations
– Easy-to-use control features
– Output range selection
– Enabling or disabling OVP
– Setting the OVP trip levels
– Clearing the OVP conditions
– Setting and displaying the voltage and current limit values
– Storing or recalling the operating state
– Resetting the power supply to the power-on state
– Returning the power supply to the local mode from the remote mode
– Retrieving or scrolling error messages on the display
– Viewing the calibration message or system firmware revision
– Calibrating the power supply, including changing the calibration secure code
– Configuring the remote interfaces
– Enabling or disabling the output
Keysight E364xA User’s and Service Guide 27
1 Getting Started
When operated over the remote interface, the E364xA power supplies can be both
a listener and a talker. Using an external controller, you can instruct the power
supply to set the output and to send the status data back over the GPIB or
RS-232 interface. Capabilities include the following features:
– Voltage and current programming
– Voltage and current readback
– Present and stored status readback
– Programming syntax error detection
– Complete self-test
The front panel Vacuum-Fluorescent Display (VFD) includes:
– Displaying the actual values of the output voltage and current (meter mode)
– Displaying the limit values of the voltage and current (limit mode)
– Checking the operating status from the annunciators
– Checking the type of error from the error codes (messages)
Front panel binding posts are available to connect load wires for bench operation.
Connections to the power supply’s output and to chassis ground are made to the
rear output terminals.

WARNING
Floating the power supply output at more than ±60 Vdc from the chassis
presents an electric shock hazard to the user.
Do not float the outputs at more than ±60 Vdc when uninsulated sense wires
are used to connect the (+) output to the (+) sense and the (–) output to the
(–) sense terminals on the back of the unit.

NOTE
Preparing the Power Supply
Checking the power supply
1 Check the shipped items.
Verify that you have received the items listed in “Standard Shipped Items” on
page 30. If anything is missing or damaged, contact your nearest Keysight
Sales Office.
2 Connect the power cord and turn on the power supply.
The front panel display will light up briefly while the power supply performs its
power-on self-test. The GPIB address is also displayed. To review the
power-on display with all annunciators turned on, hold down as you turn
on the power supply. If the power supply does not turn on properly, refer to
“Connecting power to the power supply” on page 33.
3 Perform a complete sel f-test.
The complete self-test performs a more extensive set of tests than those
performed at power-on. Hold down as you turn on the power supply and
hold down the key until you hear a long beep. The self-test will begin when
you release the key following the beep.
If the self-test fails, refer to Chapter 8, "Service and Maintenance" for
instructions on returning the power supply to Keysight for service.
The power supply is shipped from the factory with a power-line cord that has a
plug appropriate for your location. Your power supply is equipped with a 3-wire
grounding type power cord; the third conductor being the ground. The power
supply is grounded only when the power-line cord is plugged into an appropriate
receptacle. Do not operate your power supply without adequate cabinet ground
connection.
