the a layer of scale between the transducers and pipe inside wall).

Question

: Why is the CL output abnormal?

Answer

: Check to see if the desired current output mode is set in Window M55.

Check to see if the maximum and minimum current values are set properly in Windows M56 and M57.

Re-calibrate CL and verify it in Window M49.

Question

: Why is the flow rate still displayed as zero while there is fluid obviously inside the pipe and a symbol

of "R" displayed on the screen?

Answer

: Check to see if "Set Zero" was carried out with fluid flowing inside the pipe (Refer to Window M42).

If it is confirmed, recover the factory default in Window M43.
