TROUBLESHOOTING
5.3 OTHER PROBLEMS AND SOLUTIONS
1) Q: Why the instrument displays 0.0000 flow
rate while the liquid in the pipe is actually flowing?
The signal strength is checked to be good (the
working status is “R”) and the signal quality Q has a
satisfactory value.
A:
The problem is likely to be caused by the incorrect
“Zero Point” setting. The user may have conducted the
“Zero Point” setup while the flow was not standstill.
To solve this problem, use the ‘Reset Zero’ function in
menu window M43 to clear the zero point.
2) Q: The displayed flow rate is much lower or much
higher than the actual flow rate in the pipe under
normal working conditions. Why?
A:
The entered offset value might be wrong. Enter ‘0’
offset in window M44.
Incorrect transducer installation. Re-install the
transducers carefully.
The ‘Zero Point’ is wrong. Go to window M42 and redo
the “Zero Point” setup. Make sure that the flow inside
the pipe is standstill. No velocity is allowed during this
setup process.
3) Q: Why the battery can not work as long as the
time indicated on M07?
A: The battery may have come to the end of its service
life. Replace it with a new one.
New battery is not compatible with the battery estimating
software. The software needs to be upgraded. Please
contact the manufacturer.
The battery has not been fully charged.
There is indeed a time difference between the actual
working time and the estimated one, especially when
the terminal voltage is in the range from 3.70 to 3.90
volts. Therefore, the estimated working time is for
reference only
