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
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 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.
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. It is important to know and understand he
maximum measurement voltage from the probe tip to the probe reference lead.
The voltage rating depends 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.
WARNING: To prevent damage to the alligator clip insulation, do not use in high A/m magnetic fields at high frequencies, which
can cause induction heating of the jaws.
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.
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.

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.
Disconnect power
To avoid electric shock, switch off the product power and disconnect the power cord from the mains power before removing any covers or
panels, or opening the case for servicing.
Use care when servicing with power on
Dangerous voltages or currents may exist in this product. Disconnect power, remove battery (if applicable), and disconnect test leads
before removing protective panels, soldering, or replacing components.
Verify safety after repair
Always recheck ground continuity and mains dielectric strength after performing a repair.
