(2)
Enter 0 in M29
§5.3 Other Problems and Solutions
(1)
Q: Why does the instrument display 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:
(a)
The entered offset value might be wrong. Enter ‘0’offset in window M44.
