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.
