80:Adhesion Wng
–
Slight adhesion to
electrodes.
Clean and check the electrodes.
Refer to parameter K13.
82:Auto Zero Wng
–
Results of automatic zero
adjustment are higher than
the rated values.
Carry out adjustment as follows:
• Check if the flowtube is filled with
fluid.
• Check if the flow velocity is
completely zero.
• Check the condition of grounding.
83:Fix Cur Wng – The current value is fixed.
Confirm whether the flow rate is in
excess of the upper limit (108%) or
below the lower limit (-8%), or
whether upon entry to the Test Mode
or not.
90:Disp SW Wng
(only for display unit)
–
Display unit switches are not
operating.
Investigate whether the display unit
cover is fitted or whether the cover’s
glass surface is dirty.
84:Disp Over Wng
(only for display unit)
–
Overflow in the display digits during
instantaneous flow rate display.
Check whether parameter C43 is
correct.
