Note

power supply is unregulated (the channel output mode displayed as UR). In this mode, the output is not predictable. The unregulated condition may be caused by the fact that the AC line voltage is below the specifications. This condition may occur temporarily. For example, when the output voltage is programmed for a large change, the output capacitor or a large capacitive load will charge up until the current reaches the setting value. During the ramp-up of the output voltage, the power supply will be in the unregulated mode. During the transition from CV to CC (e.g. transition caused by a short circuit on the output), the unregulated condition may occur temporarily.

Use the 9-pin RS232 cable (female-to-female, straight) to connect the power supply to the PC through the RS232 interface on the rear panel.

2. Set the parameters for the RS232 interface

Press System, and then select the "Inter." tab. Set the parameters (baud rate and parity) for the RS232 i nterface based on the set t ing descriptions in "RS232

Interface Setting".

3. Add the device resource

DP700 User’s Guide 3-1

Start Ultra Sigma, and then click "RS232". A window is displayed as shown in

RIGOL Chapter 3 Remote Control

Figure (a).

(a)

As shown in Figure (a), in the "R S232 Setting " tab, set Baud Rate, Parity, Data Bits, and Stop Bit that match the current parameters of the RS232 interface of the instrument (Note: You must select "None" under the "Fl ow C ont rol " option, and select "\n" under the "End Mark" option). After completing the set tings, click "Test". If the test succeeds, a dialog box, as shown in Figure (b), is displayed.

(b)

Note: If the test fails, check whether the instrument can com municate with th e PC via the RS232 cable normally, and whether the current RS232 settings in Ultra Sig ma match those of the instrument.

In the dialog box shown in Figure (b), click "OK". Then the "Add" button in the "RS232 Setting" tab in Figure (a) will be enabled. Click "Add", and then the currently selected instrument resource will be displayed on the right section of the window, as shown in Figure (c). Then, click "OK" to add the instrument resource.

position, whether the fuse conforms to the fuse rating, and whether the fuse is intact. For fuse replacement, refer to "Fuse Replacement".

(4) If the problem still persists, contact RIGOL.

2. The constant volta ge output is abnormal.

(1) Check whether the max output power meets the load requirement. (2) Check whether there is a short across the cable that connects the l oad and

the power supply, and check whether the connection is in good condition. (3) Check whether there is a problem with the load. (4) Check whether the current setting value is proper. If the value is too low,

increase the value appropriately. (5) If the problem still persists, contact RIGOL.

3. The constant current output is abnormal.

(1) Check whether the max output power meets the load requirement. (2) Check whether there is a broken circuit across the cable that connects the

load and the power supply, and check whether the connection is in good

condition. (3) Check whether there is a problem with the load. (4) Check whether the voltage setting value is proper. If the value is too low,

increase the value appropriately.
