Agilent Technologies 6812B, 6813B, 6811B manual Using the Keypad, Checkout Procedure

3 - Turn-On Checkout

Using the Keypad

	(shift)			Some of the front panel keys perform two functions, one labeled in black and
p		q		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.
	and			These keys let you scroll up and down through the choices in the presently
À			Ã	selected function menu. All menu lists are circular; you can return to the
				starting position by continuously pressing either key.
	and			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.

⊃

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 ↑. Delete more digits by repeatedly pressing this key.

Enter

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 ac source. After pressing Enter, the ac source returns to Meter mode in most cases. In Harmonic or List mode, the ac source displays the next point in the list.

Checkout Procedure

WARNING: LETHAL VOLTAGES. Ac sources can supply 425 V peak at their output. DEATH on contact may result if the output terminals or circuits connected to the output are touched when power is applied.

The output test requires that you connect light bulbs to the output of the unit and apply a potentially hazardous voltage of 120 Vac. Properly shield all connections and wires.

The test in this section checks for output voltage and current on the ac source by having you connect light bulbs to the output of the unit. The following equipment is recommended for performing this output checkout procedure:

♦1 - 100 W light bulb

♦1 - light bulb socket

♦wires for connecting socket to the unit

NOTE: When the ac source is turned on as shipped from the factory, it asserts the *RST state. You can subsequently program the unit to turn on according to the state stored in *RCL location 0, as explained in Chapter 4. The following procedures assume that the unit turns on in the *RST state.

Make sure that the unit is turned off, and make the following connections to the output.
