6. PARAMETER DESCRIPTION
IMPORTANT
(1) Test output has priority over flow rate mea-
surement signals. When carrying out flow
rate measurements, be sure to always return
to “Normal”.
(2) Upon entry to the Test Mode, all output
terminals will simultaneously adopt test
condition.
(3) “Normal” will be restored when the power is
turned off or when 30 minutes have elapsed
since entry to Test Mode.
(4) In Test Mode, the warning 83: Fix Cur Wng
will be displayed as a warning message. (For
more details, refer to Section 6.5 Alarm
Functions.)
[N11: Test Output Value] Setting for test output
values
During loop testing, current output (4 to 20mA),
totalization, and pulse will be output in accordance
with this parameter’s setting, and values can be set
when “Test” has been selected for N10: Test Mode.
With multiple ranges or when performing forward/
reverse flow measurements, setting should be done
using a percentage of the maximum range.
[N20: Test SO1] Setting for SO1 output terminal
condition during testing
This parameter sets the condition of the SO1 status
output terminal during loop testing. Setting is possible
when “Test” has been selected for N10: Test Mode.
Setting Function
SO1 output terminal in Open (Off) condition
SO1 output terminal in Closed (On) condition
Open (Off)
Closed (On)

[N21: Test SO2] Setting for SO2 output terminal
condition during testing
This parameter sets the condition of the SO2 status
output terminal during loop testing. Setting is possible
when “Test” has been selected for N10: Test Mode.
Setting Function
SO2 output terminal in Open (Off) condition
SO2 output terminal in Closed (On) condition

[N24: Test SI2] Display for SI2 status input terminal
condition during testing
This parameter is used to display the condition of the
SI2 status input terminal during testing.

(12) Menu P: Parameter Protection items
Menu P contains items that are relevant to write
protection and passwords.
[P10: Key Code] Parameter of the display restriction
This parameter restricts access to the Service Mode.
NOTE
Write Protect function
᭿ The parameters P20 through P23 are set
when using the write protect function. Specifi-
cally, this function responds to a hardware
switch or the setting of a software password,
and it protects parameters from being over-
written.
᭿ If the hardware switch is set to “Protect”, it will
not be possible to overwrite parameters;
furthermore, this condition will be maintained
until the switch is set to “Enable”.
᭿ For more details regarding hardware switch
settings, refer to Section 10.2.3: Setting of
Write Protect Switch.
