Punch Tape Recording Rain Gage

Inspection and Preventative Maintenance

Introduction | Check List | Download | Review Questions


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.
