§5.3 Other Problems and Solutions
(1)
When the actual flow inside the pipe is not standstill, but the instrument displays 0.0000 for
the flow rate, and ‘R’ displaying signal strength and the signal quality Q (value) has a
satisfactory value?
The problems are likely caused by the user who has used the ‘Set Zero’ function on this
non-standstill flowing pipe. To solve this problem, use the ‘Reset Zero’ function on menu
window M43.
(2)
The displayed flow rate is much lower or much higher than the actual flow rate in the pipe
under normal working conditions.
(a)
There is probably an offset value wrongly entered by the user in M44. Enter ‘0’ in
M44.
(b)
Problem with transducer installation.
(c)
There is a ‘Zero Point’. Try to ‘zero’ the instrument by using M42 and make sure that
the flow inside the pipe should be standstill.
(3)
The battery can not work as long as the time period as indicated by M07
(a)
Battery should be replaced due to the end of the service life.
(b)
Newly changed battery does not fit the battery estimating software. Customizing the
battery with the software should be taken. Please contact the factory.
(c)
The battery has not been fully recharged or the recharge has been stopped too many
