theProcessAlarm(SignalOverow)occurs.
Thepipemustbefullylledwithliquid.
• The instrument checks whether the pipe is
empty or not by measuring the resistance
between the electrode and the ground.
Therefore, it cannot check the status
depending on the conditions in the pipe,
electrode, and noise at the installation sites.
In this case, set this parameter to “No.” Make
sure that the check of the empty status may
failinthecaseofahighviscosityuidor
adhesiveuid.
• It takes 10 to 15 minutes to occur the Empty
Pipe Alarm. The Process Alarm (Signal
Overow)mayoccurduringtheperiodfrom
the empty status to the Empty Pipe Alarm.
• When using the empty check function, set
the appropriate parameters based on the
above table. The default setting is “No.”
• Each of the setting values has the following
features. Before using the instrument,
conrmwhathappensintheemptyandfull
status by checking the setting values in the
order:High→Middle→Low.
Example: In the case of High
1) Set the parameter to “High,” empty the pipe,
andconrmthatthealarmoccurs.Duetothe
Empty Pipe Alarm taking 10 to 15 minutes,
theProcessAlarm(SignalOverow)occurs
in this period. If the Empty Pipe Alarm
does not occur in the empty status, the
empty check cannot be carried out. Set the
parameter to “No” in this case.
2) If the alarm is not released after the pipe
isfullylledwithliquid,thesettingvalueis
incorrect. Set the parameter to “Middle” or
“Low” accordingly.

[K21: DC Voltage A] Display of the voltage level at
electrode A
This parameter is used to display the DC voltage
level at electrode A. The possibility of adhesion at
the electrode A is higher when this value becomes
high.
[K22: DC Voltage B] Display of the voltage level at
electrode B
This parameter is used to display the DC voltage
level at electrode B. The possibility of adhesion at
the electrode B is higher when this value becomes
high.
[K23: Empty Level] Setting of the voltage level for
empty pipe detection at the electrodes
This parameter is used to set the voltage level for
empty pipe detection. The parameter would be set
as default value without change for typical use.
This parameter is changed to smaller value when
the Empty Pipe Alarm occurs frequently even if the
lledsituation.
(10) Menu M: Various Adjustment Function
Setting items
Menu M contains items that are relevant to
automatic adjustments.
[M10: Auto Zero Exe] Execution of automatic zero
adjustment function
→ Refer to the description of parameter B50.
[M11: Autozero Time] Setting of execution time for
automatic zero adjustment
This parameter is used to set the execution time of
automatic zero adjustment.
Use the instrument with the default setting “450
seconds”. When the execution time is short, an
error may occur.
[M12: FL Zero(IEL)] Display of the result of
automatic zero adjustment (excitation current (Low))
This parameter is used to display the result of
automatic zero adjustment (excitation current (Low)
at B50(M10): Auto Zero Exe. It is possible to set
