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
use the instrument only specified by this manual.
Use Proper Power Cord.
Only the power cord designed for the instrument and authorized by local country
could be used.
Ground the Instrument.
The instrument is grounded through the Protective Earth lead of the power cord.
To avoid electric shock, it is essential to connect the earth terminal of the power
cord to the Protective Earth terminal before connecting any inputs or outputs.
Connect the Probe Correctly.
If a probe is used, do not connect the ground lead to high voltage since it has
isobaric electric 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.
Use Proper Overvoltage Protection.
Make sure that no overvoltage (such as that caused by a thunderstorm) can reach
the product, or else the operator might be exposed to the danger of electrical
shock.
Do Not Operate Without Covers.
Do not operate the instrument with covers or panels removed.
