Safety Requirement
Safety specifications and safe use
General Safety Summary
Please review the following safety precautions carefully before putting the
instrument into operation so as to avoid any personal injury or damage to the
instrument and any product connected to it. To prevent potential hazards,
please follow the instructions specified in this manual to use the instrument
properly.
Use Proper Power Cord
Only the exclusive power cord designed for the instrument and authorized for
use within the local country could be used.
Connect the Probe Correctly
If a probe is used, do not connect the ground lead to high voltage since it has
isobaric potential as the ground.
Observe All Terminal Ratings
To avoid fire or shock hazard, observe all ratings and markers on the
instrument and check your manual for more information about ratings before
connecting the instrument.
