4: Maintenance & Repair
This instrument does not contain any user-serviceable parts. The following notes are provided as a guide to
general equipment care
WARNING
Do not disassemble this unit unless advised by Greyline.
Return the unit to an approved service agent or place of purchase
for further advice.
1. Ensure the unit is switched off and disconnected from the mains, then wipe the exterior of the instrument with
a clean, damp cloth or paper towel. The use of a solvent may damage the surface.
2. The instrument contains a rechargable battery, dispose safely and in accordance with the local regulations in
force in the country of operation.
3. 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.
4. 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 guide rails using an
absorbent paper towel and a general purpose solvent cleaner.
5. 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.
6. Regularly check all cables/parts for damage. Replacement parts are available from Greyline.
7. Ensure the person who services your instrument is qualified to do so. If in doubt, return the instrument to
Greyline with a detailed report on the nature of any problem.
8. Ensure that suitable precautions are taken when using any materials to clean the instrument/sensors.
9. The instrument and sensors should be calibrated at least once every 12 months. Contact Greyline or your
local service agent for details.
10. When returning product to Greyline make sure it is clean and please notify Greyline if the instrument has
been in contact with any hazardous substances.
11. If the instrument was supplied with dust or dirt caps make sure they are re-fitted when the instrument is not in
use.
