Code M08 Display
Cause
Solution
*R
System Normal
* System normal
No errors
*J
SCPU Fatal Error
* Hardware defect
* Contact the factory
*I
Signal Not Detected
*Signal not detected.
*Spacing is not correct
between the transducers or
not enough couplant
applied to face of
transducers.
*
Transducers installed
improperly.
*
Scale is too thick.
*
New pipe liner.
*
Attach transducer to the
pipe and tighten it
securely. Apply a plenty
of couplant on transducer
and pipe wall.
*
Remove any rust, scale,
or loose paint from the
pipe surface. Clean it with
a file.
*
Check the initial
parameter settings.
*
Remove the scale or
change the scaled pipe
section. Normally, it is
possible to change a
measurement location.
The instrument may run
properly at a new site with
less scale.
*
Wait until liners
solidified and saturated.
*H
Low Signal Strength
*
Low signal strength.
*
Cause refers to
above-mentioned reasons.
* Solution refers to
above-mentioned
solutions.
*H
Poor Signal Quality
*
Poor signal quality
*
All reasons are included
in the above-mentioned
causes.
* Solution refers to
above-mentioned
solutions.
*E
Current Loop over 20mA
(No influence normally.
Ignore it if no current
output is being used.)
*
4-20mA current loop
over 120%.
*
Improper settings to
current loop output.
* Check settings
（
refer to
Window M56
）
and
confirm if actual flow is
too high.
*Q
Frequency output over set
value No influence
normally. Ignore it if no
frequency output is being
used.
*
Frequency output over
120%.
*
Improper settings to
frequency output or actual
flow are too high.
* Check settings
（
refer to
Window M66-M69
）
and
confirm if the actual flow
is too high.
