Precautions during measurement
WARNING
If the instrument is used in locations where the rating
indicated on the instrument or probes is exceeded,
the instrument may be damaged resulting in personal
injury. Do not use the instrument in such locations.
See “Measurement categories” (p. 9).
• With regard to the 10 A range, the maximum input
current is 10 A DC/10 Arms AC. Supplying a current
in excess of the maximum input may damage the
instrument and result in personal injury. Do not
supply current in excess of the specied limit. (Only
the DT4282)
Observe the following to avoid electric shock and/or
short circuits.
• Hazardous voltage may be generated in a free
measurement terminal. Do not touch the free
terminal.
• Use only test leads and optional equipment
specied by our company.
• Do not allow the metal part of the test lead to touch
any exposed metal, or to short between 2 lines.
Never touch the metal end.
• When connecting the clip-type test lead to the
active terminal, do not allow the lead to touch any
exposed metal, or to short between 2 lines.
• When the clamp-on probe is opened, do not allow
the metal part of the clamp to touch any exposed
metal, or to short between 2 lines, and do not
