Normal Self Test Indications

If the supply passes the self test, the display will first show all segments of the LCD display with annunciators on as illustrated in Figure 3-2.

Figure 3-2. Test Pattern of all Display Segments at Power-on

After all segments are displayed, the supply's HP-IB address will appear for approximately 2 seconds as shown in Figure 3-3. As shipped from the factory, the power supply's address is set to 5. You must know this address before you can remotely program your supply (see Reading the HP-IB Address, page 39).

Figure 3-3. Typical Address Display During Power-On

When self test is successfully completed, the output voltage and current readings (both approximately 0) for output 1 will appear in the display as shown in Figure 3-4. Note that the CV annunciator will also indicate that the output is in the constant voltage mode.
