To Connect to Power Supply

Two kinds of AC power inputs are supported by DL3000 series electronic load. When the DL3000 series is connected to different power sources, the AC selector setting on its rear panel is different, as shown in Table 1.

Table 1 AC Input Power Specification and AC Selector Setting

Please strictly follow the steps below to connect the DL3000 electronic load to the power supply.

1. Check the input power
   Ensure that the AC power to be connected to the load conforms to the AC input power requirement specified in Table 1.

2. Check the AC selector
   Ensure that the AC selector setting (115 or 230) on the rear panel of the load matches the actual AC input power (For the match relationship, refer to Table 1).

3. Check the fuse
   When leaving the factory, the load has installed a fuse that conforms to the destination country standard. Please refer to the “fuse rating” on the rear panel of the load to ensure that the fuse matches the actual AC input power.

4. Connect the AC power
   Plug the specified power cord available in the accessories into the AC power supply connector of the instrument, and then connect the instrument to the properly grounded AC power.

To Power on the instrument

After the instrument is connected to the power source, press the Power key at the left bottom of the front panel to power on the instrument. When the instrument is turned on, it will undergo a self-test. If the instrument passes the self-test, the welcome interface is displayed; otherwise, self-test failure information will be displayed. At this time, please contact RIGOL distributors.

Tip
After powering off the electronic load, please wait for at least 1 s before you power it on again.

To Use the Built-in Help System

The built-in help system provides help information for any key on the front panel (except parameter input area) and menu keys, which are convenient for you to get the descriptions of the function keys or menus, as shown in Figure 4.

Figure 4 Help Information Interface

1. Get the built-in help information
   Press , and then “Help” will be displayed at the top of the interface, being highlighted. At this time, press the corresponding function key or menu key to enter the corresponding help information interface.

2. Page up/down operation
   If the help information is displayed in several pages, press Previous to go to the previous page or press Next to go to the next page. You can also use the arrow keys or the knob to page up/down the help information.

3. Exit the current help information interface
   When the help information is displayed, press OK to exit the current help information interface and return to the previous interface.

Parameter Setting Method

Most parameters can be set by operating the keys on the front panel. The common setting methods are listed below. The setting method for certain parameters is different from the methods below, refer to the relevant chapters of this manual for the further explanation.

Method 1: Use the numeric keys

1. In the main interface, press the specified menu key to switch the parameter focus; in the guide interface, use the arrow keys to switch the parameter focus.
2. Enter a value by using the numeric key. While entering a name, press to delete the unwanted character if necessary.
3. When setting resistance, press the specified menu key and select “Ω” or “kΩ” to be the unit.
   When setting period/width, press the specified menu key and select “ms” or “s” to be the unit.
   When setting frequency, press the specified menu key and select “Hz” or “kHz” to be the unit.
   When setting other parameters, press OK to confirm the input.

Method 2: Use the knob or the arrow keys

1. In the main interface, press the specified menu key to switch the parameter focus.
2. Press the Left/Right arrow key to move the cursor to a desired position.
3. Press the Up/Down arrow key or rotate the knob to modify the value.

Remote Control

DL3000 electronic load can be connected to the PC via the USB, LAN, GPIB, or RS232 interface to build communication and realize remote control. The remote control can be realized by using SCPI (Standard Commands for Programmable Instruments) commands. DL3000 electronic load supports two ways of remote control: user-defined programming and PC software (e.g. RIGOL Ultra Sigma).

When the instrument is in remote control, the icon is displayed on the interface. The keypads on the front panel are locked. At this time, you can press Local to exit the remote mode.
