1.Connect the power cord to the power source (for Series 668xA & 669xA, turn on the safety disconnect switch).

2.Turn the front panel power switch to ON (1).

3.The power supply undergoes a self-test when you turn it on. If the test is normal, the following sequence appears on the LCD:

a.Series 664xA/665xA - The GPIB address (factory default is 5).

b.Series 667xA/668xA/669xA - The GPIB address (factory default is 5). This is then followed by PWR ON INIT for approximately 10 seconds.

4.The display then goes into the meter mode with the Dis annunciator on and all others off. “Meter mode” means that the VOLTS digits indicate the output voltage and the AMPS digits indicate the output current. These values will be at or near zero.

5.Verify that the power supply fan is on by placing your hand near the rear grill to feel the air flow. You may also be able to hear the fan operating.

6.Press once. The Dis annunciator will go off and the CV annunciator will go on .

Note

If the power supply detects an error during self-test, the display will show an error message. Go to “In

 

Case of Trouble” at the end of this chapter.

Shifted Keys

Some of the front panel keys perform two functions, one labeled in black and the other in blue. You access the blue function

by first pressing the blue key, which is not labeled. When the Shift annunciator is on, you will know you have access to the key's shifted (blue) function.

Backspace Key

The key is an erase key. If you make a mistake entering a number and have not yet entered it (have not pressed

), you can delete the number by pressing . You may delete as many numbers as you wish by repeatedly pressing this key.

Output Checkout (All Models)

Important When the power supply is turned on, it asserts the state stored in EEPROM memory location 0. For a new supply, this is the factory default (*RST) state. The following procedures assume that the factory default state is still in location 0 (Turn-On Conditions in “Chapter 5 - Front Panel” for details).
