Inspection and Cleaning

General Care

This subsection describes how to determine whether the AWG2005 needs cleaning, and how to do the cleaning. Inspection and cleaning are preven) tive maintenance procedures. When done regularly, preventive maintenance may prevent AWG2005 malfunction and enhance reliability.

Preventive maintenance consists of visually inspecting and cleaning the AWG2005 and using general care when operating it.

How often to do maintenance depends on the severity of the environment in which the AWG2005 operates.

The cabinet helps keep dust out of the AWG2005 and is a major component of the instrument cooling system. The cabinet should normally be in place when operating the AWG2005. The AWG2005 front cover (optional accesso) ry) protects the front panel and display from dust and damage. Install it when storing or transporting the instrument.

Inspection and Cleaning Procedures

Inspect and clean the AWG2005 as operating conditions require. The collec) tion of dirt on components inside can cause them to overheat and break down. (Dirt acts as an insulating blanket, preventing efficient heat dissipa) tion.) Dirt also provides an electrical conduction path that can cause an instrument failure, especially under high)humidity conditions.

WARNING

To avoid personal injur! or death due to electric shock, unplug the power cord from the line voltage source before cleaning the AWG2005.
