ASOS MAINTENANCE (pictures)
Course Number: S1003
Type of Course: Residence
Objectives:
To provide NWS Electronic Technicians with the knowledge and
skills necessary to calibrate, perform preventive maintenance,
and perform corrective maintenance on the ASOS system including
all sensors. Corrective maintenance will be taught to the Field
Replacement Unit (FRU) level consistent with the current ASOS
maintenance philosophy. Students will understand both the diagnostic
and operational levels of ASOS communications software. Students
will leave the course with an understanding of the overall concept
of the ASOS system.
Contents:
This course will cover organization and use of system manuals;
hands-on use of diagnostic firmware for the detection of failed
sensors and assemblies, and testing of replaced units; hands-on
use of built-in test equipment; removal and replacement
instructions for failed assemblies; preventive maintenance
requirements and procedures; the running of remote maintenance
monitoring and diagnostic systems test; maintenance alignment of
sensors; system interconnections; firmware installation and
trouble-shooting; and an introduction to all aspects of ASOS software.
Information on current ASOS problem areas as identified by field
technicians and specialists which will be of interest to technicians
until the problems have been corrected.
Length: 104 Hours (13 working days)
Suggested Review:
1) DataComms CBIs DC-BAS-1, DC-TRM-1, DC-TEL-1, DC-PRO-1 & DC-MOD-1
