NOTICE
Precautions for Use
When there is a possibility of an electric discharge occurring from
the measurement target to the main body, “ ” is displayed on
the screen along with an alarm sound to inform the user of the
abnormally high voltage. If a grounding wire is not connected,
WARNING
there is a risk of receiving an electric shock from the
measurement target, so make sure that a grounding wire is
connected. Also, measurement beyond the specified
measurement range can cause failure of the unit.
• Before and while operating this product, confirm that its
performance and functions operate correctly.
• Implement sufficient safety measures to prevent human and
property damage in case this product fails.
• Note that functions and performance cannot be guaranteed if
the product is used outside of the standards written in the
NOTICE
Warnings and cautions specific to the SK-H Series
The SK-H Series is a high-voltage device that is not designed to be explosion
proof. Before using the product, be sure to read the following warnings and
cautions carefully.

Safety precautions on laser products
• This product uses a semiconductor laser as its light source.
• Performance of procedures, controls or adjustments other than those specified
herein may result in hazardous radiation exposure.
• Follow the instructions mentioned in this manual. Failure to do so may result in
injury to the human body (eyes and skin).
specifications or if the product is modified.
• When this KEYENCE product is used in combination with other
devices, functions and performance may be degraded
depending on the operating conditions and environment.
• Do not use this product for the purpose of protecting a human
body or a part of the human body.
• This product is not intended for use as an explosion-proof
product. Do not use this product in a hazardous location and/or
potentially explosive atmosphere.
• To avoid electric shock and to ensure accurate measurement of
static electricity, be sure to completely ground the SK-H050/
055's ground terminal.
• Do not use the product in locations where it might catch fire or
explode due to flammable solvents or particles.
• High voltages are applied to the SK-H055, so ensure that fluids
such as water, oil, and flammable solvents do not splash onto
the SK-H055. Failure to do so may cause the electrical isolation
to be destroyed, which may lead to electric shock or product
breakdown.
• Keep metallic objects such as tools or wires away from the
metal plate of the SK-H055. Failure to do so may lead to electric
CAUTION
shock or product breakdown.
• Do not directly touch the metal plate of the SK-H055. Doing so
may lead to electric shock.
• Do not operate this product with wet hands. Doing so may lead
to electric shock.
• Be sure to turn the power off before performing maintenance or
inspections. Performing these operations with the power on
may lead to electric shock or product breakdown.
• If you observe any abnormality in this KEYENCE product,
immediately turn off the power and contact the nearest
KEYENCE office. Do not try to repair the product yourself. Doing
so may lead to electric shock or product breakdown.
• Do not touch the SK-H050's panel or operation keys with hard
objects such as tools. Doing so may lead to accidents or
product breakdown.
• Do not drop the SK-H050 or subject it to strong impacts. Doing
so may lead to accidents or product breakdown.
• Prevent objects from coming in contact with the sensing unit of
the SK-H050 during measurement.
Contact with objects prevents the sensing unit from performing
accurate measurements, which may lead to accidents or
product breakdown.
• Do not use the SK-H050 for any purpose other than measuring
static electricity.
Precautions on class 1 laser products
• Do not stare into the direct or specularly reflected beam.
• Laser emission from this product is not automatically stopped when it is disas-
sembled. Do not disassemble this product.

• Locations in which the product is directly subjected to breezes
from air conditioners or similar devices
• Locations in which there are volatile, flammable substances or
corrosive gases
• Locations in which a large amount of dust, salt, metal particles,
or soot is present
• Locations in which liquids such as water, oil, or chemicals
splash on the product
• Locations in which strong magnetic or electric fields are
generated
