SAFETY SUMMARY

The following general safety precautions must be observed

during all phases of operation, service, and repair of this

instrument. Failure to comply with these precautions or with

specific warnings elsewhere in this manual violates safety

standards of design, manufacture, and intended use of the

instrument. Agilent Technologies assumes no liability for the

customer’s failure to comply with these requirements.

Before Applying Power

Verify that the product is set to match the available line

voltage.

Ground The Instrument.

This product is a Safety Class I instrument (provided with a

protective earth terminal). To minimize shock hazard, the

instrument chassis and cabinet must be connected to an

electrical ground. The instrument must be connected to the

ac power supply mains through a three-conductor power

cable, with the third wire firmly connected to an electrical

ground (safety ground) at the power outlet. Any interruption of

the protective(grounding) conductor or disconnection of the

protective earth terminal will cause a potential shock hazard

that could result in personal injury. If the instrument is to be

energized via an external autotransformer for voltage reduc-

tion, be certain that the autotransformer common terminal is

connected to the neutral (earthed pole) of the ac power lines

(supply mains).

Do Not Operate In An Explosive Atmosphere

Do not operate the instrument in the presence of flammable

gases or fumes.

Regulatory Information for Canada

This ISM device complies with Canadian ICES-001.

Cet appareil ISM est conforme à la norme NMB-001 du Can-

ada.

KEEP AWAY FROM LIVE CIRCUITS.

Operating personnel must not remove instrument covers.

Component replacement and internal adjustments must be

made by qualified service personnel. Do not replace compo-

nents with power cable connected. Under certain conditions,

dangerous voltages may exist even with the power cable

removed. To avoid injuries, always disconnect power, dis-

charge circuits and remove external voltage sources before

touching components.

SAFETY SYMBOLS

Instruction manual symbol; the

product will be marked with this

symbol when it is necessary for

the user to refer to the instruction

manual.

Indicate earth(ground) terminal.

The WARNING sign denotes a

hazard. It calls attention to a proce-

dure, practice, or the like, which, if

not correctly performed or adhered

to, could result in personal injury.

Do not proceed beyond a WARN-

ING sign until the indicated con-

ditions are fully understood and

met.

The CAUTION sign denotes a haz-

ard. It calls attention to an operating

procedure, or the like, which, if not

correctly performed or adhered to,

could result in damage to or destruc-

tion of part or all of the product. Do

not proceed beyond CAUTION sign

until the indicated conditions are fully

understood and met.

GENERAL INFORMATION

Description

This operating and service manual covers three dual range

Agilent power supplies, E3610A, E3611A, and E3612A. All

models are compact, general purpose bench supplies that

are particularly useful for powering developmental IC circuits,

both linear and digital. Unless stated otherwise, all informa-

tion in this manual applies equally to all three models. The

desired output range is selected by the front panel RANGE

push button. The output can be continuously adjusted for volt-

age and current throughout either output range.

The front panel VOLTAGE control can be used to establish

the voltage limit when the supply is used as a constant cur-

rent source and the CURRENT control can be used to estab-

lish the output current limit when the supply is used as a

constant voltage source. The CC SET push button allows the

current limit value to be conveniently set using the CURRENT

control without shorting the output.

The front panel includes a digital voltmeter/ammeter. A 3 1/2

digit (E3611A 3 digit) voltage display and 3 digit current dis-

play accurately show the output voltage and current respec-

tively. The output ratings for each model are shown in the

Specifications Table.
