ECO 422
7–1
Maintenance
This section discusses the various options available for servicing the Tektronix
ECO 422. It also contains instructions for preventive maintenance, general
troubleshooting, and corrective maintenance. If the instrument does not function
properly, troubleshooting and corrective measures should be taken immediately
to circumvent additional problems.
Service Options
A number of servicing options are available. They range from returning the
instrument to Tektronix for repair and/or recalibration, to a major assembly
exchange, to full component level servicing by the customer (at the installation
site). Each of these options should be investigated as to which will be the most
time efficient and cost effective.
Tektronix maintains service centers around the world to provide quick turn-
around repair and recalibration services. When this service is used, even during
the warranty period, the instrument should be tagged and repackaged according
to the instructions at the end of this section.

Inspection and Cleaning
Preventive maintenance consists of cleaning, lubricating, visual inspection,
checking performance, and readjusting the ECO 422 on a regular schedule. The
Inspection and cleaning schedule should be established based on the amount of
use and the surrounding environment of the ECO 422. Under average conditions,
a preventive maintenance check should be performed on a one year interval
(severe environmental conditions may dictate a shorter time interval).
Clean the instrument often enough to prevent dust or dirt from accumulating.
Dust accumulating in the instrument acts as an insulating blanket, preventing
proper cooling, and possibly causing overheating and component breakdown.
