HEALTH AND SAFETY
Some organic materials may attack plastic parts and
cause early degradation. Contact with such materials
should be avoided.
7. HEALTH AND SAFETY
AUDIT 207 thickness gauge and accessories are
NOT
intrinsically safe or flameproof, and should not be used
in hazardous areas without the necessary local
precautions being enforced for the use of non-
intrinsically safe equipment.
Always adhere to site rules and guidelines concerning
Health & Safety when using the AUDIT Instrument.
Always wear safety equipment appropriate to the area
where the measurement is to be made.
There are no user serviceable parts inside the
instrument case of the AUDIT 207 Service work should
only be carried out by qualified personnel.
Care should be taken that the couplant used is neither
harmful to the operator nor will it attack the probe. For
advice please contact Baugh & Weedon.

PRINCIPLE OF OPERATION
EC Declaration of Conformity
UNIT Audit 207 Ultrasonic Thickness Gauge
WEE compliance Registration No WEE/FK0103WV
The equipment is supplied in a single commercial
carton, containing the items previously detailed, ensure
that all the items of equipment are accounted for when
unpacking.
Equipment should be examined for signs of transit
damage. Damaged equipment
SHOULD NOT BE
USED
.
Retain the carton in the event the equipment
has to be returned to the manufacturer for period
certification.
3. PRINCIPLE OF OPERATION
AUDIT 207 measures thickness by injection of a short
burst of high frequency sound (ultrasound) into the
work piece and measuring the time taken for the burst
to travel through the material and be reflected back
from the far surface. As the velocity at which the sound
travels is constant for a given material the thickness
can be computed and displayed.
Thickness readings are held for 5 Minutes after the
probe is removed from the work piece.

TECHNICAL SPECIFICATION
Backlight is operated by the
UNIT
key, selectable on/off
Low battery is indicated by the battery symbol located
at the top right of the display.10 hours use available. In
normal use battery life will be much greater than the
above specification. This is due to the intermittent use
of the instrument rather than a continuous test ,
detailed above.

CARE AND MAINTENANCE
6. CARE & MAINTENANCE
This equipment is protected against hostile
environments as defined in section 2.5 and is designed
for prolonged use in the field without any special
maintenance other than routine cleaning.
All connectors should be kept free of foreign matter and
the transducer face regularly cleaned with soft material
such as tissue paper.
To ensure trouble free operation, when not in use the
AUDIT 207 thickness gauge should be returned to the
carrying case in a clean condition.
This equipment should only be operated by qualified
personnel.
Transducers and leads are consumable items and are
subject to wear and deterioration during use. The life
of these parts can be much extended by keeping them
in a dry, clean condition, and storing them in suitable
protective containers. During use avoid 'scrubbing' the
probe face on the work piece. Only take spot
measurements at the selected locations.
