Safety Summary
The following general safety precautions must be observed during all phases of operation 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. Keysight Technologies assumes no liability
for the customer's failure to comply with these requirements.
GENERAL
This product is a Safety Class 1 instrument (provided with a protective earth terminal). The protective features of
this product may be impaired if it is used in a manner not specified in the operation instructions.
Any LEDs used in this product are Class 1 LEDs as per IEC 825-1.
This ISM device complies with Canadian ICES-001. Cet appareil ISM est conforme à la norme NMB-001 du Canada.
ENVIRONMENTAL CONDITIONS
This instrument is intended for indoor use in an installation category II, pollution degree 2 environment. It is
designed to operate at a maximum relative humidity of 95% and at altitudes of up to 2000 meters. Refer to the
specifications tables for the ac mains voltage requirements and ambient operating temperature range.
BEFORE APPLYING POWER
Verify that the product is set to match the available line voltage, the correct fuse is installed, and all safety
precautions are taken. Note the instrument's external markings described under "Safety Symbols".
GROUND THE INSTRUMENT
To minimize shock hazard, the instrument chassis and cover must be connected to an electrical ground. The
instrument must be connected to the ac power mains through a grounded power cable, with the ground 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.
ATTENTION: Un circuit de terre continu est essentiel en vue du fonctionnement sécuritaire de l'appareil.
Ne jamais mettre l'appareil en marche lorsque le conducteur de mise … la terre est d‚branch‚.
FUSES
Only fuses with the required rated current, voltage, and specified type (normal blow, time delay, etc.) should be
used. Do not use repaired fuses or short-circuited fuseholders. To do so could cause a shock or fire hazard.
DO NOT OPERATE IN AN EXPLOSIVE ATMOSPHERE
Do not operate the instrument in the presence of flammable gases or fumes.
DO NOT REMOVE THE INSTRUMENT COVER
Operating personnel must not remove instrument covers. Component replacement and internal adjustments must be
made only by qualified service personnel.
Instruments that appear damaged or defective should be made inoperative and secured against unintended
operation until they can be repaired by qualified service personnel.

Safety Considerations
This dc source is a Safety Class 1 instrument, which means it has a protective earth terminal. That
terminal must be connected to earth ground through a power source equipped with a ground receptacle.
Refer to the Safety Summary page at the beginning of this guide for general safety information. Before
installation or operation, check the dc source and review this guide for safety warnings and instructions.
Safety warnings for specific procedures are located at appropriate places in the guide.

Description
Both the Keysight 66312A Dynamic Measurement DC Source and the Keysight 6611C, 6612C, 6613C
and 6614C System DC Power Supplies combine two instruments in one unit. They include a dc source,
which produces dc output with programmable voltage and current amplitude, and a highly accurate
voltage and current meter, with the capability to measure very low-level currents. Additionally, the
Keysight 66312A Dynamic Measurement DC Source has the ability to measure and characterize output
voltage and current of pulse or ac waveforms.
Capabilities

Output Voltage and Current control with 12-bit programming resolution

Extensive measurement capability:
dc voltage and current.
rms and peak voltage and current (Keysight 66312A only).
16-bit measurement resolution (low range accurate down to 2 microamperes).
Triggered acquisition of digitized current and voltage waveforms (Keysight 66312A
only).

Front panel control with 14-character vacuum fluorescent display, keypad, and rotary control for
voltage and current settings.

Built-in GPIB and RS-232 interface programming with SCPI command language.

Non-volatile state storage and recall with SCPI command language.

Over-voltage, over-current, over-temperature, and RI/DFI protection features.

Extensive selftest, status reporting, and software calibration.
Front Panel Controls
The front panel has both rotary (RPG) and keypad controls for setting the output voltage and current. The
panel display provides digital readouts of a number of output measurements. Annunciators display the
operating status of the dc source. System keys let you perform system functions such as setting the GPIB
address and recalling operating states. Front panel Function keys access the dc source function menus.
Front panel Entry keys let you select and enter parameter values. Refer to chapter 5 for a complete
description of the front panel controls.
Remote Programming
NOTE: When shipped, all units are set to the SCPI programming language. The language setting
is saved in non-volatile memory.
To change the programming language from SCPI to Compatibility language, press the
front panel Address key, use to scroll to the LANG command, press to select
SCPI, then press Enter. Refer to the Programming Guide supplied with your dc source
for further information about remote programming.
The dc source may be remotely programmed via the GPIB bus and/or from an RS-232 serial port. GPIB
programming is with SCPI commands (Standard Commands for Programmable Instruments), which make
the dc source programs compatible with those of other GPIB instruments. Compatibility commands are
also included to make the dc source compatible with the Keysight 6632A, 6633A, and 6634A Series dc
power supplies (refer to appendix D in the the Programming Guide). Dc source status registers allow
remote monitoring of a wide variety of dc source operating conditions.
