1.6 Grounding
!
WARNING
Be sure to connect the tester to an electrical ground (safety
ground). If the output to a conveyer or peripheral device that is connected to
an earth ground or a nearby commercial power line is short-circuited without
grounding, the tester chassis is charged to an excessively high voltage,
resulting in extreme danger.
This tester is designed as a Class I equipment (equipment protected against
electric shock with protective grounding in addition to basic insulation).
Therefore, electric shock may occur without proper grounding.
To ensure safety, be sure to ground the tester.
