Important safety information

To avoid ﬁre or personal injury

Ground the prod uct . This product is indirectly grounded through the

grounding conductor of th e mainframe power cord. To avoid electric shock, the grou nding conductor must be connected to earth ground. Before making connections to the input or output terminals of the product, make sure that the product is properly grounded.

Do not disable the power cord grounding connection.

Connect and disconnect properly. Do not connect or disconnect prob es

or test leads while they are connected to a voltage source.

Use o nly 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 av o id ﬁre or shock hazard, observe all

ratings and markings on the product. Consult the produ ct 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 transm itted to the p rod uct.

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 measuring terminals on this pro duct are not rated for connection to mains Category III or IV circuits, or to mains Category II circuits greater than 100 V.

When connected to circuits other than mains, the maximum transient overvoltage rating is 400 V peak.

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.

Important safety information

Do not operate with susp ecte d failures. If you suspect that there is damage

to this product, have it inspected by qual iﬁed service personnel.

Disable the produ ct if it is dam a ged . Do not use the p ro duct 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 dam aged , if there is exposed metal, or if a wear indicator shows.

Examine the exterior of the product before yo u use it. Look for cracks or missing pieces.

Pollution degree descriptions

A measure of the contaminants that could o ccur in the environment around and within a product. Typically the internal environment insid e a product is considered to be the same as the external. Products should be used only in the environment for which they are rated.

Pollution degree 1. No po llution or only dry, nonconductive pollution occurs. Products in this category are generally encapsulated, hermetically sealed, or located in clean rooms.

Pollution degree 2. Normally only dry, nonconductive pollution occurs. Occasionally a temporary conductivity that is caused by condensation must be expected. T his location is a typical ofﬁce/home environment. Temporary condensation occurs only when the product is out of service.

Pollution degree 3. Conductive pollution, or dry, nonconductive pollution that beco mes conductive due to condensation. These are sheltered locations where neither temperature nor humidity is controlled. The area is protected fro m direct sunshine, rain, or direct wind.

Pollution degree 4. Po llution that generates persistent conductivity through conductive dust, rain, or snow. Typical outdoor locations.
