Compliance Information
Pollution Degree Description
A measure of the contaminants that could occur in the environment around and within a product. Typically the internal environment
inside 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 pollution 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. This 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 becomes conductive due to condensation. These
are sheltered locations where neither temperature nor humidity is controlled. The area is protected from direct sunshine,
rain, or direct wind.
Pollution Degree 4. Pollution that generates persistent conductivity through conductive dust, rain, or snow. Typical outdoor
locations.
Pollution Degree
Pollution Degree 2 (as defined in IEC 61010-1). Note: Rated for indoor use only.
Installation (Overvoltage) Category Descriptions
Terminals on this product may have different installation (overvoltage) category designations. The installation categories are:

Measurement Category IV. For measurements performed at the source of low-voltage installation.
Measurement Category III. For measurements performed in the building installation.
Measurement Category II. For measurements performed on circuits directly connected to the low-voltage installation.

AC/DC Measurement capability
50 A peak pulse current (pulse widths
<10 μs)
5 A and 30 A range settings
1 mA sensitivity (on TekVPI oscilloscopes
that support the 1 mV/div setting)
1% DC Accuracy (typical)
One-button degauss/autozeroing
Probe control through the TekVPI
oscilloscope menus or remotely through
