Important safety information
This manual contains information and warnings that must be followed by the user for safe operation and to keep the product in a safe
condition.
To safely perform service on this product, see the Service safety summary that follows the General safety summary.
General safety summary
Use the product only as specified. Review the following safety precautions to avoid injury and prevent damage to this product or any
products connected to it. Carefully read all instructions. Retain these instructions for future reference.
This product shall be used in accordance with local and national codes.
For correct and safe operation of the product, it is essential that you follow generally accepted safety procedures in addition to the safety
precautions specified in this manual.
The product is designed to be used by trained personnel only.
Only qualified personnel who are aware of the hazards involved should remove the cover for repair, maintenance, or adjustment.
Before use, always check the product with a known source to be sure it is operating correctly.
This product is not intended for detection of hazardous voltages.
Use personal protective equipment to prevent shock and arc blast injury where hazardous live conductors are exposed.
While using this product, you may need to access other parts of a larger system. Read the safety sections of the other component manuals
for warnings and cautions related to operating the system.
When incorporating this equipment into a system, the safety of that system is the responsibility of the assembler of the system.
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. Do not use the
provided power cord for other products.
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.
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.
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.
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.
Important safety information
5 Series MSO Service Manual MSO54, MSO56, MSO58 7
Do not operate without covers Do not operate this product with covers or panels removed, or with the case open. Hazardous voltage
exposure is possible.
Avoid exposed circuitry Do not touch exposed connections and components when 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.
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 installation instructions in the manual 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.
Provide a safe working
environment
Always place the product in a location convenient for viewing the display and indicators.
Avoid improper or prolonged use of keyboards, pointers, and button pads. Improper or prolonged keyboard
or pointer use may result in serious injury.
Be sure your work area meets applicable ergonomic standards. Consult with an ergonomics professional to
avoid stress injuries.
Use care when lifting and carrying the product. This product is provided with a handle or handles for lifting
and carrying.
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.
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 protective barrier, protective finger guard, or tactile indicator 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:
Important safety information
5 Series MSO Service Manual MSO54, MSO56, MSO58 8
• 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 the probe reference lead to earth ground only.
Do not connect a current probe to any wire that carries voltages or frequencies 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.
Ground-referenced
oscilloscope use
Do not float the reference lead of this probe when using with ground-referenced oscilloscopes. The
reference lead must be connected to earth potential (0 V).
Service safety summary
The Service safety summary section contains additional information required to safely perform service on the product. Only qualified
personnel should perform service procedures. Read this Service safety summary and the General safety summary before performing any
service procedures.
To avoid electric shock Do not touch exposed connections.
Do not service alone Do not perform internal service or adjustments of this product unless another person capable of rendering
first aid and resuscitation is present.
