Safety Information for the SK-1000 series
Warming up
Leave the SK Series about 30 minutes after turning on the power.
The circuit is not stable immediately after the power turns on, so the display value
may gradually fluctuate.
Abnormal Conditions
Precautions for Use
Installation environment
To use this product normally and safely, do not install this product in the following
locations. Product failure may occur.
• High-humidity, dusty or poorly-ventilated locations
• High-temperature locations where the unit is exposed to direct sunlight
• Locations where there is corrosive or combustible gas
• Locations where the unit may be directly subjected to vibration or impact
• Locations where water, oil or chemicals may splash onto the unit
• Locations that cause the unit to discharge its static electricity
Influence of dirt
Measurement errors may occur due to dust, water, oil, etc.
Anti-noise prevention
When the unit is installed near electric noise source such as a power source or
high-voltage line, operational errors or product failure may occur. Take adequate
measures such as using a noise filter, separating cables or insulating the sensor
amplifier and the sensor head.
WARNING
• This product is only intended to detect the charge on object(s).
Do not use this product for the purpose to protect a human body
or a part of human body.
• This product is not intended for use as explosion-proof product.
Do not use this product in hazardous location and/or potentially
explosive atmosphere.
NOTICE
If the following conditions occur, turn OFF the power immediately.
Continuing to use this product under abnormal conditions may
cause product failure.
• When water or foreign matter enters the SK Series
• When the SK Series is dropped or the case is damaged
• If smoke or unpleasant odor is present.
CAUTION
• Use with the correct power source and voltage. Otherwise, fire,
electric shock or product failure may result.
• Do not attempt to open or modify the SK Series. Doing so may
cause fire or electric shock.
NOTICE
• Before disconnecting the cables, make sure to turn off the main
unit and devices connected to the main unit. Otherwise, the unit
may be damaged.
• Do not turn off the power while modifying settings. Some or all
of the setting data may be lost.
• The measurement area is basically a guide for measurement. A
proper size of target with respect to the measurement area is
recommended to ensure a more accurate measurement.
Power ON Reset
After the power is turned ON, it will take approx. 3.5 seconds for the measurement
to start. The judgment results will be output after the sampling rate has elapsed.
Other Precautions
Power source
• Noise superimposed on the power supply may cause malfunction. Use a direct
current stabilized power source which uses an insulation transformer.
• When using a commercially available switching regulator, make sure to ground
the frame ground terminal.
 Grounding precautions
A grounding wire is present in the I/O cable of the SK-1000 Series.
