Safety Information
The following general safety precau-
tions must be observed during all
phases of operation of these instru-
ments. Failure to comply with these
precautions or with specific warnings
or operating instructions in the product
manuals violates safety standards of
design, manufacture, and intended use
of the instruments. Keysight Technolo-
gies assumes no liability for the cus-
tomer's failure to comply with these
requirements.
General
Do not use these instruments in any manner
not specified by the manufacturer. The pro-
tective features of these instruments must
not be impaired if it is used in a manner
specified in the operation instructions.
Before Applying Power
Verify that all safety precautions are taken.
Make all connections to the instruments
before applying power. Note the external
markings described under "Safety Symbols".
Ground the Instrument
Keysight instruments are provided with
a grounding-type power plug. The
instruments must be connected to an
electrical ground to minimize shock
hazard. The ground pin must be firmly
connected to an electrical ground
(safety ground) terminal at the power
outlet. Any interruption of the protec-
tive (grounding) conductor or discon-
nection of the protective earth terminal
will cause a potential shock hazard
that could result in personal injury.
Unless otherwise noted in the specifi-
cations, these instruments or system is
intended for indoor use in an installa-
tion category II, pollution degree 2
environment per IEC 61010-1 and 664
respectively. They are designed to
operate at a maximum relative humid-
ity of 5% to 80% at 40 °C or less (non-
condensing). These instruments or sys-
tem are designed to operate at alti-
tudes up to 3000 meters, and at
temperatures between 0 and 55 °C.Do
Not Operate in an Explosive Atmo-
sphere Do not operate in the presence
of flammable gases or fumes.
iv
Do Not Operate Near Flammable
Liquids
Do not operate the instruments in the
presence of flammable liquids or near
containers of such liquids.
Cleaning
Clean the outside of the Keysight
instruments with a soft, lint-free,
slightly dampened cloth. Do not use
detergent or chemical solvents.
Do Not Remove Instrument Cover
Only qualified, service-trained person-
nel who are aware of the hazards
involved should remove instrument
covers. Always disconnect the power
cable and any external circuits before
removing the instrument cover.
Keep away from live circuits
Operating personnel must not remove
equipment covers or shields. Proce-
dures involving the removal of covers
and shields are for use by service-
trained personnel only. Under certain
conditions, dangerous voltages may
exist even with the equipment
switched off. To avoid dangerous elec-
trical shock, DO NOT perform proce-
dures involving cover or shield removal
unless you are qualified to do so.
DO NOT operate damaged
equipment
Whenever it is possible that the safety
protection features built into these
instruments have been impaired, either
through physical damage, excessive
moisture, or any other reason,
REMOVE POWER and do not use the
instrument until safe operation can be
verified by service-trained personnel. If
necessary, return the product to a Key-
sight Technologies Sales and Service
Office for service and repair to ensure
the safety features are maintained.
DO NOT block the primary
disconnect
The primary disconnect device is the
appliance connector/power cord when
an instrument used by itself, but when
installed into a rack or system the dis-
connect may be impaired and must be
considered part of the installation.
Do Not Modify the Instrument
Do not install substitute parts or per-
form any unauthorized modification to
the product. Return the product to a
Keysight Sales and Service Office to
ensure that safety features are main-
tained.
In Case of Damage
Instruments that appear damaged or
defective should be made inoperative
and secured against unintended oper-
ation until they can be repaired by
qualified service personnel.
Measurement Limits
The Truevolt Series DMMs provide pro-
tection circuitry to prevent damage to
the instrument and to protect against
the danger of electric shock, provided
the Measurement Limits are not
exceeded. To ensure safe operation of
the instrument, do not exceed the
Measurement Limits shown on the
front and rear panel.
The DMMs comply with EN/IEC 61326-
2-1, for sensitive test and measure-
ment equipment.
When subjected to transient radiated
and/or conducted electromagnetic
phenomena, the DMMs may have tem-
porary loss of function or performance
which is self-recovering. Recovery may
take longer than 10 seconds.
When subjected to continuously pres-
ent electromagnetic phenomena, some
degradation of performance may
occur.
