Should a fault be indicated at the ray passage test stage, the display will show ER instead of OK. After
4 seconds, automated probe cleaning procedure will start and last for 5 minutes. The display will then read
CLEAN.UTSP 5 MIN
11111111 …………...
On the second line is displayed step by step, the actual number of the minute of the cleaning procedure is
displayed. Every fourth seconds one numeral is added, the line will be filled up by 15 same numbers within 1 minute,
after elapsing this time the displayed numbers disappear and next new numbers start to display for a time 1 minute.
After the probe cleaning, another ray passage test is performed. Should even then the test result be negative, the
following message will appear on the display:
DEFECT
END OF TEST
The meter needs be put out of service and either sent for repair to the manufacturing plant or a service technician
be asked to come and repair the meter on site.
Should a fault be indicated at the ultrasonic wave propagation velocity measurement and the measured velocity lie
outside the range of physically defined limits (VUTS < 900 m/s, VUTS > 1700 m/s), the probe cleaning procedure will
be initiated (unless it has already been performed) and the velocity measurement will be repeated. Should even then
the test result be unsatisfactory, the display will read:
DEFECT
END OF TEST
and the test sequence will be terminated.
Should the measured velocity lie outside preset limits but within the range of physically possible values, the
following message will appear on the display
UTS RATE LIMITS
ADJUSTMENT
and the actual limits will automatically be re-adjusted with respect to the measured value. The display will in that case
read
RATE LIMITS OK
END OF TEST
and, after another 4 seconds, the meter will resume the normal measurement mode.
Should the meter function still be unsatisfactory, it is possible to repeat the tests. In the case of repeated failure to
set the meter right, contact the meter manufacturer.
