SAFETY
The following
safety precautions
PRECAUTIONS
the Model ~193A
should be observed before operating
This instrument is intended for use by qualified personnel who recognize shock huxds
.~nd are i,lmiliar
with the safety precautions required to avoid possible injury. Read WET the manual carefully before operating
this instrument.
Exercise extreme caution when a shock hazard is present at the instrument’s input. The American National
Standards Institute (ANSI) states that a shock hazards exists when voltage levels greater than 3OV rms or
42.4V peak are present. A good safety practice is to expect that a hazardous voltage is present in any unknown
circuit before measuring.
Ins ect the test leads for possible wear, cracks or breaks before each use. If any defects are found, replxe
wt .R test leads that have the same measure of safety as those supplied with the instrument.
For optimum safety do not touch the test leads or the instrument while power is applied to the circuit under
test. Turn the power off and discharge all capacitors, before connecting or disconnecting the instrunwnt.
Always disconnect all unused test leads from the instrument.
Do not touch any object which could provide a current path to the common side of the circuit under lest
or power line (earth) ground. Always make measurements with dry hands while standing on ‘1 dry, ill-
s&ted surface, capable of withstanding
the voltage being measured.
Exercise extreme safety when testing high energy power circuits (AC line or mains, etc). Refer to the t ligh
Energy Circuit Safety Precautions found in paragraph 2.6 (Basic Measurements).
Do not exceed the instrument’s
section.
