Safety Precautions

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 specifications or if the product is modified.

NOTICE • 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.

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.

	•	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

NOTICE	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.

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).
