SAFETY PRECAUTIONS

The following safety precautions should be observed before using this product
and any associated instrumentation. Although some instruments and accessories
would normally be used with non-hazardous voltages, there are situations where
hazardous conditions may be present.

This product is intended for use by qualified personnel who recognize shock haz­ards and are familiar with the safety precautions required to avoid possible injury.
Read the operating information carefully before using the product.

Exercise extreme caution when a shock hazard is present. L
present on cable connector jacks or test fixtures. The American National Stan­dards Institute (ANSI) states that a shock hazard exis
er than 30V RMS, 42.4V peak, or 60VDC are present. A good safety practice is

to expect that hazardous voltage is present in any unknown circuit before
measuring.

Before operating an instrument, make sure the line cord is connected to a proper­ly grounded power receptacle. Inspect the co
jumpers for possible wear, cracks, or breaks before each use.

For maximum safety, do not touch the product, test cables, or
ments while power is applied to the circuit under test. ALWAYS remove power
from the entire test system and discharge any capacitors before: connecting or
disconnecting cables or jumpers, installing or removing switching cards, or mak­ing internal changes, such as installing or removing jumpers.

Do not touch any object that could provide a current path to the common side of
the circuit under test or power line (earth) ground. Always make measurements
with dry hands while standing on a dry, insulated surface capable of withstanding
the voltage being measured.

Do not exceed the maximum si
