Punch Tape Recording Rain Gage
Inspection and Preventative
Check List |
The routine inspection of the Punch Tape Recording Rain
Gage is the key to maximizing gage availability. Time spent
during periodic site visits performing preventive maintenance
(PM) will result in a marked decrease in time spent on future
emergency visits and gage repairs. A standard PM routine is also
one of the most effective means of maximizing productivity during
your station visit. Every visit to Punch Tape Gage should include
documented PM service.
The purpose of this module is to provide an overview of the PM
services that you should cover during your site visits. At the
end of this lesson you may download a sample checklist which can
used to document individual Preventative Maintenance visits to a
gage. You can use the checklist as is or modify it to suit your
needs. It is also suggested that a PM log be maintained for each
gage as a ready troubleshooting tool for future visits.
