Safety Precautions
The following safety precautions should be observed before using this product and associated
computer. Although some instruments and accessories would normally be used with non-haz-
ardous 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.
Lethal voltage may be present on cables, connector jacks, or test fixtures.
The American National Standard Institute (ANSI) states that a shock hazard exists when
voltage levels greater than 30V RMS, 42.4V peak, or 60 VDC are present. A good safety
practice is to expect that hazardous voltage is present in any unknown circuit before touching
or disconnecting the line cord. Before operating an instrument, make sure the line cord is
connected to a properly grounded power receptacle. Inspect the connecting cables and test
leads for possible wear, cracks, or breaks before each use.
For maximum safety, do not touch the product, test cables, or any other of the instrument parts
while power is applied to the circuit under test. ALWAYS remove power from the entire test
system before connecting cables or jumpers, installing or removing cards from the computer,
or making internal changes, such as changing card address. 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 keep dry hands while handling the instrument. If you are using test fixtures, keep the
lid closed while power is applied to the device under test. Safe operation requires that the
computer lid be closed at all times during operation.
Carefully read the Safety Precautions instructions that are supplied with your computer.
Instruments, cables, leads or cords should not be connected to humans. Before performing any
maintenance, disconnect the line cord and all test cables. Finally, maintenance should be
performed by qualified service personnel only. If you have no past experience in instrument
servicing, we strongly recommend that installation and initial tests on the instrument be done
by your dealer or by the factory itself.
