To avoid potential hazards, use the instrument in the manner specified in this user’s guide.

The instrument should be serviced only by qualified personnel.

To Avoid Fire or Personal Injury

Use proper power line. Only the special power line of the products approved by

the State should be used.

Insert or draw properly. Do not insert draw when the probe and the testing lead are connected with the power.

Ground the instrument. This generator is grounded through the protective terra conductor of the power cord. To avoid electric shock, the grounding conductor must be connected to the earth ground. Make sure that the instrument is properly grounded before connecting the input or output terminals.

Connect the probe properly. Connect the output terminal of the signal properly, make sure that the potential difference between the output terminal of the signal’s terra line and the earth is lower than 40V DC. The probes’ ground terminals are at the same voltage level with the earth terminal of the instrument. Do not connect the ground terminals to a high voltage.

Observe All the Ratings of the Terminal. To avoid fire or shock, observe all the ratings and symbols that marked on the instrument. Read the user’s guide carefully before making connections to the instrument.

Do not operate without Covers. Do not operate your generator without covers or panels.
