INTRODUCTION
1. INTRODUCTION.
The AUDIT 207 is a Precision Ultrasonic Thickness
handheld gauge for fast and accurate metric or Imperial
measurement of the thickness of a wide range of metals
and plastics materials, performed with access to only one
side of the material being measured.
This handbook describes the instrument and how to
use it to its best advantage.
1.1 Cautionary information.
The AUDIT 207 is intended to satisfy a wide range of
applications, including corrosion monitoring.
However, the user should be aware that corrosion in a
pipeline or vessel is not uniform and thickness readings
taken on a sampling basis, example testing to a grid
pattern may not indicate the most severely corroded
areas.
It is therefore important that inspection schedules
should be developed by competent engineers and that
measurement of the integrity of a pipeline or vessel
should take account of this factor. In addition, users
should be properly trained in the use of ultrasonic
thickness gauges and be made aware of the limitations
of the equipment and the proposed testing schedule.

SERVICE & MAINTENANCE
8.3 Service Repairs and Maintenance
Repairs not covered by the guarantee or carried out
after the guarantee period will be charged at the current
hourly service rate, plus the cost of materials.
Goods for repair must be sent at the Purchaser's
expense and be accompanied by the Purchaser's
written order describing the defect and authorising the
company to invoice the purchaser for labour, materials
and return delivery costs.
No guarantee or service work will be undertaken until a
written order is received.
Baugh & Weedon undertakes to offer repair and
maintenance services to the AUDIT 207 thickness
gauge for a period of not less than five (5) years from
the date of original dispatch.
The Company cannot make any such undertaking after
that period although it will use its best endeavours in
every case.
