Precautions in Use
(1)
Before starting the measurement
When turning on the power, don’t connect DUT.
Before starting the measurement, check to see the output power level.
(2)
Removing of case
Do not open the case to one except service man of our company.
The R3267 Series has a high temperature part and a high pressure part.
(3)
When abnormality occurs
When smoke rises from the R3267 Series, smell nastily, or rear unusual sound feel, turn off the
power switch. Pull out power cable from the outlet. And contact to our company.
The address and the telephone number of our company are in the end of this manual.
(4)
Electromagnetic interference.
Electromagnetic interference may be caused to the television or the radio.
If the R3267 Series power is turned off and the electromagnetic interference is reduced, then the
R3267 Series has caused the problem.
Prevent electromagnetic interference by the following procedure.
•
Change the direction of antenna of the television or the radio.
•
Place the R3267 Series the other side of the television or the radio.
•
Place the R3267 Series away from the television or the radio.
•
Use another line of power source for the television or the radio than the R3267 Series.

Prevention of Electrostatic Buildup
To prevent damages to semiconductor parts from electrostatic discharge (ESD), the precautions
shown below should be taken. We recommend that two or more measures be combined to provide
adequate protection from ESD. (Static electricity can easily be built up when a person moves or an
insulator is rubbed.)
Countermeasure example
Human body:
Use of a wrist strap (see Figure 1-4).
Floor in the work area:
Installation of a conductive mat, the use of conductive shoes, and
grounding (see Figure 1-5).
Benchboard:
Installation of a conductive mat and grounding (see Figure 1-6).
