Lithium Battery Recycling
The 53220A/53230A counters contain a 3 V “coin cell” lithium battery. Keysight
recommends that this battery be replaced every year at the instrument’s 1-year
calibration interval. Replacement procedures are provided in the 53220A/53230A
Service Guide.
Option 300 provides battery operation of the 53220A/53230A using a 12 lithium
battery. Performance of this battery will degrade over time as a function of the
number of battery charge/discharge cycles.
Refer to local, state, or Federal regulations when disposing of, or recycling either
battery.
Safety Symbols
The following symbols on the instrument and in the documentation indicate
precautions which must be taken to maintain safe operation of the instrument.

disconnected from AC mains when
power switch is in standby position.
Frame or chassis (ground) terminal
Caution, risk of danger (refer to this
manual for specific Warning or Caution
information)

Safety Information
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 or operating instructions in the product manuals 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
Do not use this product in any manner not specified by the manufacturer. The
protective features of this product may be impaired if it is used in a manner not
specified in the operation instructions.
Before applying power
Verify that all safety precautions are taken. Note the instrument's external
markings described under Safety Symbols.
Ground the instrument
The Keysight 53220A/53230A is provided with a grounding-type power plug. The
instrument chassis and cover 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
protective (grounding) conductor or disconnection of the protective earth terminal
will cause a potential shock hazard that could result in personal injury.
Fuses
The Keysight 53220A/53230A is provided with an internal line fuse appropriate for
the line voltages listed on the instrument. This fuse is not user accessible.
Do not operate in an explosive atmosphere
Do not operate the instrument in the presence of flammable gases or fumes.

Keysight 53220A/53230A User’s Guide 7
Do not operate near flammable liquids
Do not operate the instrument in the presence of flammable liquids or near
containers of such liquids.
Do not remove the instrument cover
Only qualified, service-trained personnel 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.
Do not modify the instrument
Do not install substitute parts or perform any unauthorized modification to the
product. Return the product to a Keysight Sales and Service Office for service and
repair to ensure that safety features are maintained.
In case of damage
Instruments that appear damaged or defective should be made inoperative and
secured against unintended operation until they can be repaired by qualified
service personnel.
Cleaning the instrument
Clean the outside of the instrument with a soft, lint-free, slightly-dampened cloth.
Do not use detergents or chemical solvents.
WARNING
Do not connect the input channels of the 53220A/53230A to AC line-voltage
mains or to circuits derived from AC mains. The instrument must be used in
CAT I (isolated from mains) applications only. Do not use in other IEC
Measurement Category (CAT II, CAT III, or CAT IV) applications. Failure to
observe these precautions may result in electric shock and serious
personal injury.

Protection limits
The Keysight 53220A/53230A 350 MHz Universal Frequency Counter/Timer
provides protection circuitry to prevent damage to the instrument and to protect
against the danger of electric shock, provided the Protection Limits are not
exceeded and the instrument is properly grounded. To ensure safe operation of
the instrument, do not exceed the Protection Limits defined on the front panel:
WARNING
The BNC shells of the input terminals are connected to the instrument
chassis. Verify signal polarity before making any connections to the input
terminals.
1 Watt Max into 50W
!
Channel / Setup
WARNING
During battery operation, the maximum measured signal supplied by the
user is +42 V.
WARNING
Product Options 201/202 add parallel Channel 1 and Channel 2 inputs to the
rear panel of the instrument. Signals on the center conductor of either
panel’s channel BNCs are also present on the corresponding center
conductor of the BNC on the opposite panel.

Keysight 53220A/53230A User’s Guide 9
Installing the instrument
The Keysight 53220A/53230A operates in the following line-voltage ranges:
100 V to 240 V, 50 Hz to 60 Hz
100 V to 127 V, 440 Hz
90 VA Max
Instrument ventilation is through the sides and rear. Do not obstruct the
ventilation holes in any of these locations.
Battery operation
When operating the 53220A or 53230A under battery power (Option 300), failure
to observe the following warnings may result in damage to the instrument,
electric shock, and serious personal injury:
WARNING
Connect the instrument chassis to earth ground during battery operation to
minimize shock hazard. Any interruption or disconnection of the protective
earth terminal will cause a potential shock hazard that could result in
personal injury.
WARNING
Under battery power, the instrument chassis may float to the potential of the
measured signal supplied by the user.
