5: Maintenance & Repair

5.1 Introduction

This instrument does not contain any user-serviceable parts. The following notes are provided as a guide to

general equipment

5.2 General care

The following notes are provided as a guide to general equipment care.

1. Ensure the unit is disconnected from the mains, then wipe the exterior of the instrument with a clean, damp

cloth or paper towel. Do not use a solvent-based cleaning fluid on the instrument as it could damage the

instrument surface.

2. Ensure all cables and connectors are kept clean and free from grease or contaminants. Connectors may be

cleaned with a general purpose cleaner if necessary.

3. Avoid the use of excessive grease/ultrasonic couplant on the sensors as this may impair the performance of

the equipment. Excessive grease/couplant can be removed from the sensors and transducer holders using

an absorbent paper towel and a general purpose solvent cleaner.

4. We recommend that the ultrasonic couplant is replaced on the sensors every 6 months, especially on pipes

where the application is too hot to touch. If the signal level drops below 30% this is also an indication that the

sensors need re-greasing.

5. Regularly check all cables/parts for damage. Replacement parts are available from Dwyer.

6. Ensure the person who services your instrument is qualified to do so. If in doubt, return the instrument to

Dwyer with a detailed report on the nature of any problem.

7. Ensure that suitable precautions are taken when using any materials to clean the instrument/sensors.

8. If the instrument was supplied with dust or dirt caps make sure they are re-fitted when the instrument is not in

use.
