Safety Considerations
Read the information below before using this instrument.
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 for design, manufacture, and intended use of the instrument. Keysight
Technologies assumes no liability for the customer’s failure to comply with these
requirements.
Whenever it is likely that the protection has been impaired, the instrument must
be made inoperative and be secured against any unintended operation.
If this instrument is to be energized via an autotransformer (for voltage reduction),
make sure the common terminal is connected to the earthed pole terminal
(neutral) of the power source.
Instructions for adjustments while covers are removed and for servicing are for use
by trained personnel only. To avoid dangerous electric shock, do not perform such
adjustments or servicing unless qualified to do so.
For continued protection against fire, replace the line fuse(s) with fuses of the
same current rating and type (for example, normal blow, time delay). Do not use
repaired fuses or short-circuited fuseholders.
WARNING Instructions for adjustments while covers are removed and for servicing are
for use by service-trained personnel only. To avoid dangerous electric shock,
do not perform such adjustments or servicing unless qualified to do so.
WARNING Any interruption of the protective grounding conductor (inside or outside the
product's circuitry) or disconnecting the protective earth terminal will cause
a potential shock hazard that could result in personal injury (grounding one
conductor of a two conductor outlet is not sufficient protection).

Safety Earth Ground
An uninterruptible safety earth ground must be maintained from the mains power
source to the product’s ground circuitry.
Acoustic Noise Emissions
LpA<47 dB at operator position, at normal operation, tested per EN 27779. All
data are the results from type test.
Geräuschemission
LpA<47 dB am Arbeits platz, normaler Betrieb, geprüft nach EN 27779. Die
Angagen beruhen auf Ergebnissen von Typenprüfungen.
Electrostatic Discharge Immunity Testing
When the product is tested with 8kV AD, 4kV CD and 4kV ID according to
IEC801-2, a system error may occur that may affect measurement data made
during these disturbances. After these occurrences, the system self-recovers
without user intervention.
WARNING When measuring power line signals, be extremely careful and always use a
step-down isolation transformer which output is compatible with the input
measurement capabilities of this product. This product’s front and rear
panels are typically at earth ground. Thus, never try to measure ac power
line signals without an isolation transformer.

Types of Service Available if Instrument Fails
If your Counter fails within one year of original purchase, Keysight will repair it free
of charge. If your instrument fails after your one-year warranty expires, Keysight
will repair it, or you can repair it yourself.
There are three types of repair services:
– Standard repair service—if downtime is not critical.
– Express Repair/Performance Calibration Service—if downtime is critical.
– Owner repair—repair the unit yourself using the Assembly-Level Service Guide.
Standard Repair Services (Worldwide)
Contact your nearest Keysight Service Center to arrange to have your Counter

If downtime is critical, you can receive your repaired Counter via overnight
shipment. Just call 1-800-403-0801 and ask for Express Repair/Performance
Calibration Service. When your Counter is repaired, it will be returned via
overnight shipment.
Repair Instrument Yourself
If you choose to repair the instrument yourself or would like more details on self
