Agilent Technologies 5951-2826, 5951-2827 manual Connect The Power Cord, Turn-On/Selftest, Error

Connect The Power Cord

Your Agilent Electronic Load was shipped with a power cord for the type of outlet used at your location. Connect the power cord to the ac input socket.

SHOCK HAZARD The power cord provides a chassis ground through a third conductor. Be certain that your power outlet is of the three-conductor type with the correct pin connected to earth ground (see Figure 3-1).

Turn-On/Selftest

Turn on the Electronic Load using the LINE switch on the front panel and observe the display. Immediately after turn-on, the Electronic Load undergoes a selftest that checks the GPIB interface circuitry as well as the input circuitry of the unit. All of the front panel LCD segments are momentarily activated. When selftest completes, the display should appear about the same as the one shown in Figure 3-5 with the CC annunciator being on.

Figure 3-5. Front Panel Display

After the Electronic Load has passed selftest, connect a power supply to the Electronic Load to test the input circuits as described under "Power Test".

If the unit fails any portion of the selftest, one of the following error numbers may briefly appear on the display:

	GPIB Errors		Input Errors
Display	Description	Display	Description
ERROR 4	GPIB failure	ERROR 100	Self test error
ERROR 5	Internal trigger failed	ERROR 101	Secondary RAM failure
		ERROR 102	Secondary ROM failure, power board
			disconnected or thermistor open
		ERROR 103	Secondary timer trigger failed
		ERROR 104*	Calibration EEprom failed
		ERROR 105	Main DAC high
		ERROR 106	Main DAC low
		ERROR 107	Transient DAC high
		ERROR 108	Transient DAC low
* Requires calibration.

Another indication that the Electronic Load has failed selftest is if the ERR annunciator on the display remains on after selftest completes. If the Electronic Load has failed selftest, return the unit to the nearest Agilent Sales and Service Office for repair.
