6. PARAMETER DESCRIPTION
B41/H11: Display Select2 and B42/H12: Display
Select3 as described below. (For more details, refer to
Chapter 5: Basic Operating Procedures.)
CAUTION
It is not possible to set Display Select1 to “Off”.
[B41: Display Select2] Setting of the second line
for display unit
→ This setting is linked with that of parameter H11.
This parameter selects the display content of the
second line for display unit. When “Off” is selected,
one-line display will be adopted regardless of the
setting made for B42/H12: Display Select 3.
[B42: Display Select3] Setting of the third line for
display unit
→ This setting is linked with that of parameter H12.
This parameter selects the display content of the third
line for display unit. When “Off” is selected for this
parameter, two-line display is adopted.
[B50: Auto Zero Exe] Execution of the automatic
zero adjustment function
→ This setting is linked with that of parameter M10.
This parameter executes the automatic zero adjustment
function: If “Execution” is selected, this function will
be started. “Now Auto Zero Executing...” is indicated
while the Auto Zero function is being carried out. The
result of the automatic zero adjustment is confirmed
using M11: Magflow Zero, and if the result exceeds
the rated value, the warning 82: Auto Zero Wng will
be displayed. (For more details, refer to Chapter 9:
Operation.)

(2) Menu C: Basic Setting items
Menu C principally contains the basic setting items for
the flowtube.
NOTE
In order to ensure that correct flow rate data can
be acquired, it is crucial that the nominal size,
flow rate span, and meter factor of the combined
remote flowtube are set. In cases where a
remote flowtube is ordered at the same time as
the AXFA14, or where the AXF integral flowme-
ter is ordered, the nominal size and meter factor
will be set upon shipment from the manufactur-
ing plant, and these will not require additional
setting. If the AXFA14 is ordered separately, the
default value will be set for the meter factor;
accordingly, it will be necessary to set the meter
factor indicated on your remote flowtube data
plate.
If a flow rate span was specified upon ordering,
this will be set before shipment. If this is not the
case, however, it will be necessary for the
appropriate value to be set by the user.
[C10: Tag No] Setting of the tag number
→ The setting for this parameter corresponds to one of
the ordered items.
Up to a maximum of 16 characters can be entered for
the display unit. For more details regarding the actual
characters that can be used, refer to Section 5.2.2:
Setting Mode.
NOTE
If a tag number is specified upon ordering, this
parameter is set up before shipment; however, if
this is not the case, it will be necessary for the
appropriate value to be set up by the user.
[C11: Flow Damping] Setting of the damping time
→ Refer to the description of parameter B20.
[C20: Measure Mode] Selection of dual frequency
excitation mode
Item Description
T0618.EPS
Standard DF Standard dual frequency excitation
Enhanced dual frequency excitation Enhanced DF
Enhanced DF (i.e., enhanced dual frequency excitation)
is set to stabilize measurement for difficult applica-
tions, such as for high concentration slurries or low
conductivity fluid. Note that this parameter is only
valid when this product is used in combination with an
AXF flowtube, as only supports enhanced dual
frequency excitation. (Optional code HF1 or HF2)
