Automatic zero calibration setting
Automatic zero
calibration
setting
Select “yES” when an external electric ball valve and a solenoid valve for
automatic zero calibration are installed.
Set to “no” when the automatic zero calibration function is not available or
to stop the function.
yES, no
Setting of
automatic zero
calibration start
method
Select the combined operation of the internal timer and the external
command for automatic zero calibration.

nor: Zero calibration is only started in response to the zero calibration
cycle defined by the internal timer without accepting an external
command. However, a transmission signal is held by an external
command.

or: Zero calibration is started in response to the internal timer or when
an external command is input.

And: Zero calibration is started in response to the internal timer only
while an external command is being input.

trg: Zero calibration is only started in response to an external
command (trigger for two seconds or longer) while the internal timer
function is disabled.

Automatic zero
calibration
cycle setting
Specify the calibration cycle (in hours) when the automatic zero
calibration function is available. 1 to 999
(h)
Transmission
hold time
setting after
completion of
automatic zero
calibration A transmission signal is held until the valve is returned to its original
position and the indication is stabilized after the completion of the
automatic zero calibration.
A transmission output is also held when the mode is returned to the meas
mode after the manual/automatic zero calibration, span calibration, or
valve operation from the user check menu.
60 to 600
(s)
Stability level
setting during
automatic
calibration
This value is used to compare the instantaneous and average values of
turbidity. Zero calibration is performed if the difference is constantly below
the zero stability level for the zero stability time.
0.01 to
0.05
Stability
duration setting
during
automatic
calibration
Zero calibration is performed if the difference between the instantaneous
and average values of turbidity is constantly below the zero stability level
for the zero stability time.

attempt error
E-43
Specify whether or not to display an automatic calibration attempt error
(E-43).

yES: Displays E-43 if zero calibration fails because the value is not
stabilized within the automatic zero calibration time.
Also specify this when outputting the contact.
Note, however, that the transmission output for the next measurement
is not held even when E-43 is displayed and the contact is output.
If the system judges that it is an error, measurement continues under
the condition of the latest zero calibration that has been performed
successfully. E-43 can only be cancelled next time the zero calibration
is performed successfully or zero calibration is completed manually.
An error is more likely to occur when a longer zero stability time is set.
If the time is too short, zero calibration is performed with a high
turbidity, which results in a lower measurement value.

no: No error processing is performed and measurement continues
under the condition of the previous zero calibration.
