SAFETY
Review the following safety precautions to avoid injury and prevent damage to this product or
any products connected to it. To avoid potential hazards, use the product only as specified.
WARNING: These statements identify conditions or practices that could result in personal
injury or loss of life.
CAUTION: These statements identify conditions or practices that could result in damage to
the equipment or other property.
Specific precautions
Use proper Fuse. To avoid fire hazard, use only the fuse type and rating specified
product, 10A / 600V Fast-acting (Cat. No. 22-89-0300). For fuse replacement, it is recommended
to return the tool to a factory Service/Sales Support Branch or authorized service station.
Do not operate without covers. To avoid personal injury, do not apply any voltage or current to
the product without covers in place.
Electric overload. Never apply a voltage to a connector on the product that is outside the range
specified for that connector.
Avoid electric shock. To avoid injury or loss of life, do not connect or disconnect probes or test
leads while they are connected to a voltage source.
Do not operate in wet/damp conditions. To avoid electric shock, do not operate this product in
wet or damp conditions.
