To avoid fire or personal
injury Use proper power cord. Use only the power cord specified for this product and
certified for the country of use.
Use proper power cord. Use only the power cord specified for this product and
certified for the country of use. Do not use the provided power cord for other
products.
Use proper voltage setting. Before applying power, ensure that the line selector is
in the proper position for the source being used.
Ground the product. This product is grounded through the grounding conductor of
the power cord. To avoid electric shock, the grounding conductor must be
connected to earth ground. Before making connections to the input or output
terminals of the product, ensure that the product is properly grounded. Do not
disable the power cord grounding connection.
Ground the product. This product is indirectly grounded through the grounding
conductor of the mainframe power cord. To avoid electric shock, the grounding
conductor must be connected to earth ground. Before making connections to the
input or output terminals of the product, ensure that the product is properly
grounded. Do not disable the power cord grounding connection.
Power disconnect. The power switch disconnects the product from the power
source. See instructions for the location. Do not position the equipment so that it
is difficult to disconnect the power switch; it must remain accessible to the user at
all times to allow for quick disconnection if needed.
Power disconnect. The power cord disconnects the product from the power
source. See instructions for the location. Do not position the equipment so that it
is difficult to operate the power cord; it must remain accessible to the user at all
times to allow for quick disconnection if needed.
Use proper AC adapter. Use only the AC adapter specified for this product.
Connect and disconnect properly. Do not connect or disconnect probes or test
leads while they are connected to a voltage source. Use only insulated voltage
probes, test leads, and adapters supplied with the product, or indicated by
Tektronix to be suitable for the product.
Observe all terminal ratings. To avoid fire or shock hazard, observe all rating and
markings on the product. Consult the product manual for further ratings
information before making connections to the product. Do not exceed the
Measurement Category (CAT) rating and voltage or current rating of the lowest
rated individual component of a product, probe, or accessory. Use caution when
using 1:1 test leads because the probe tip voltage is directly transmitted to the
product.
Observe all terminal ratings. To avoid fire or shock hazard, observe all rating and
markings on the product. Consult the product manual for further ratings
information before making connections to the product.
Do not apply a potential to any terminal, including the common terminal, that
exceeds the maximum rating of that terminal.
Do not float the common terminal above the rated voltage for that terminal.
The measurement terminals on this product are not rated for connection to mains
or Category II, III, or IV circuits.

power is present.
Do not operate with suspected failures. If you suspect that there is damage to this
product, have it inspected by qualified service personnel.
Disable the product if it is damaged. Do not use the product if it is damaged or
operates incorrectly. If in doubt about safety of the product, turn it off and
disconnect the power cord. Clearly mark the product to prevent its further
operation.
Before use, inspect voltage probes, test leads, and accessories for mechanical
damage and replace when damaged. Do not use probes or test leads if they are
damaged, if there is exposed metal, or if a wear indicator shows.
Examine the exterior of the product before you use it. Look for cracks or missing
pieces.
Use only specified replacement parts.
Replace batteries properly. Replace batteries only with the specified type and
rating.
Recharge batteries properly. Recharge batteries for the recommended charge
cycle only.
Use proper fuse. Use only the fuse type and rating specified for this product.
Wear eye protection. Wear eye protection if exposure to high-intensity rays or
laser radiation exists.
Do not operate in wet/damp conditions. Be aware that condensation may occur if a
unit is moved from a cold to a warm environment.
Do not operate in an explosive atmosphere.
Keep product surfaces clean and dry. Remove the input signals before you clean
the product.
Provide proper ventilation. Refer to the manual's installation instructions for
details on installing the product so it has proper ventilation.
Slots and openings are provided for ventilation and should never be covered or
otherwise obstructed. Do not push objects into any of the openings.

Important safety information
WFM2300 and WFM2200A Waveform Monitors User Manual xiii

WARNING. The product is heavy. To reduce the risk of personal injury or damage
to the device get help when lifting or carrying the product.
WARNING. The product is heavy. Use a two-person lift or a mechanical aid.
Use only the Tektronix rackmount hardware specified for this product.
Probes and test leads Before connecting probes or test leads, connect the power cord from the power
connector to a properly grounded power outlet.
Keep fingers behind the finger guards on the probes.
Remove all probes, test leads and accessories that are not in use.
Use only correct Measurement Category (CAT), voltage, temperature, altitude,
and amperage rated probes, test leads, and adapters for any measurement.
Beware of high voltages. Understand the voltage ratings for the probe you are
using and do not exceed those ratings. Two ratings are important to know and
understand:
■The maximum measurement voltage from the probe tip to the probe reference
lead.
■The maximum floating voltage from the probe reference lead to earth ground.
These two voltage ratings depend on the probe and your application. Refer to the
Specifications section of the manual for more information.
WARNING. To prevent electrical shock, do not exceed the maximum measurement
or maximum floating voltage for the oscilloscope input BNC connector, probe
tip, or probe reference lead.
Connect and disconnect properly. Connect the probe output to the measurement
product before connecting the probe to the circuit under test. Connect the probe
reference lead to the circuit under test before connecting the probe input.
Disconnect the probe input and the probe reference lead from the circuit under
test before disconnecting the probe from the measurement product.
Connect and disconnect properly. De-energize the circuit under test before
connecting or disconnecting the current probe.
Connect the probe reference lead to earth ground only.
Do not connect a current probe to any wire that carries voltages above the current
probe voltage rating.
Inspect the probe and accessories. Before each use, inspect probe and accessories
for damage (cuts, tears, or defects in the probe body, accessories, or cable jacket).
Do not use if damaged.
