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 rating
Pollution Degree 2 (as defined in IEC 61010-1). Rated for indoor, dry location use only.

This product is intended for use in nonresidential areas only. Use in residential areas may cause electromagnetic interference.
2
Emissions which exceed the levels required by this standard may occur when this equipment is connected to a test object.
3
For compliance with the EMC standards listed here, high quality shielded interface cables that incorporate low impedance connection between the cable shield and
the connector shell should be used.
4
Equipment may not meet the immunity requirements of applicable listed standards when test leads and/or test probes are connected due to coupling of
electromagnetic interference onto those leads/probes. To minimize the influence of electromagnetic interference, minimize the loop area between the unshielded
portions of signal and associated return leads, and keep leads as far away as possible from electromagnetic disturbance sources. Twisting unshielded test leads
together is an effective way to reduce loop area. For probes, keep the ground return lead as short as possible and close to the probe body. Some probes have
accessory probe tip adapters to accomplish this most effectively. In all cases, observe all safety instructions for the probes or leads used.

当该设备与测试对象连接时，可能产生超过此标准要求的辐射级别。
3
为确保符合上面列出的 EMC 标准，应使用在电缆护套和连接器外壳间包含低阻抗连接的高质量屏蔽接口电缆。
4
测试导线和/或测试探头由于电子干扰耦合而发生连接时，设备可能无法满足所列适用标准的抗干扰能力要求。为了将电磁干扰的影响降
到最低，需最小化信号无屏蔽部分与关联返回导线之间的环路面积，同时尽量让导线远离电磁干扰源。将未屏蔽的测试导线缠绕在一起
是减小环路面积的有效方法。探头方面，需要使接地回路导线的长度尽可能得短，并靠近探头主体。为了最有效地达到这一目的，一些
探头配备了附件探头端部适配器。在一切情况下，都应遵守所用探头或导线的所有安全说明。
