Introduction

Successful tests in this chapter provide a high degree of confidence that the dc source is operating properly. For verification tests, see appendix B. Complete performance tests are given in the Service Guide.

NOTE: This chapter provides a preliminary introduction to the dc source front panel. See chapter 5 for more details.

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 shift key. Release the key after you press it. The Shift annunciator will be on, indicating that you have access to any key's shifted function.

These keys let you scroll up and down through the choices in the presently selected function menu. All menu lists are circular; you can return to the starting position by continuously pressing either key.

These keys let you select the previous or the next parameter for a specific command. If the command has a numeric range, these keys increment or decrement the existing value. In meter mode, these keys can be used to adjust the magnitude of the output voltage or current. Only the flashing digit is changed by these keys. Use the á and

âkeys to move the flashing digit.

These Entry keys move the flashing digit in a numeric entry field to the right or left. This lets you increment or decrement a specific digit in the entry field using the ã and ä keys or the RPG knob.

The backspace key is an erase key. If you make a mistake entering a digit and have not yet pressed Enter, you can delete the digit by pressing Backspace. Delete more digits by repeatedly pressing this key.

Executes the entered value or parameter of the presently accessed command. Until you press this key, the parameters you enter with the other keys are displayed but not entered into the dc source. After pressing Enter, the dc source returns to Meter mode.
