OPERATION
The Special Conditions for Safe Use detailed in section 9 ATEX APPENDIX must be observed
and followed at all times.
3.1.
TURN ON SEQUENCE
To turn the unit on simply press and hold the control
button until the company logo appears on the display
and then release, this takes approximately 5 seconds.
The next screen shows the product logo. This screen
will be displayed for 5 seconds as shown by the
counter at the bottom left corner of the display.
When the countdown indicator at the bottom left of
the screen reaches zero, or the control button is
pressed, the next screen will appear.
The next screen shows the time and date currently
set in the unit.
The next screen indicates that the unit is trying to
detect the pipe diameter. While this screen is visible
the unit is shooting ultrasound into the pipe several
hundred times per second and from the received
reflections is calculating the diameter. A switch press
at this stage will have no effect. After the unit is
finished it will display the DETECTED DIAMETER
screen.
The distance in the centre of this screen shows the
average diameter which the unit detected. The next
line gives an idea of the quality of this signal path
between 00-99%. The measured diameter should be
very close to the external diameter of the pipeline but
will vary slightly due to pipe wall thickness and the
type of fluid in the pipe. Factors which could cause a
poor signal quality include how well the transducer is
coupled to the pipe surface, foreign particles within
the pipe fluid, gas bubble within the pipe fluid or non-
uniform pipe wall material.
While on the DETECTED DIAMETER screen, to re-
detect the pipe diameter, the switch can be pressed
before the counter reaches zero. If the counter
reaches zero the unit will enter DETECTION MODE 0.
See section 3.2 DETECTION MODE 0.
