IM 01E30D01-01EN
[M13: Flow Zero(IEM)] Display of the result of
automatic zero adjustment (excitation current
(Middle))
This parameter is used to display the result of
automatic zero adjustment (excitation current
(Middle) at B50(M10): Auto Zero Exe. It is possible
to set parameters as coefficient value directly.
[M14: Flow Zero(IEH)] Display of the result of
automatic zero adjustment (excitation current (High))
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
parameters as coefficient value directly.
[M15: Flow Span Adjust] Setting of adjustment
factor of flow span
This parameter is used to set the adjustment of flow
span. The adjustment is not acted when the value
is set to “1” as its default. Use this default value for
typical use.
[M20: Adjustment 4mA] Setting of adjustment for
4 mA output
This parameter is used to set the adjustment of 4
mA output. Use this default value for typical use.
[M21: Adjustment 20mA] Setting of adjustment for
20 mA output
This parameter is used to set the adjustment of 20
mA output. Use this default value for typical use.
CAUTION
The output adjustment function can match the
4mA and 20mA output to the reference meter
such as a voltmeter. In the output adjustment, it
is necessary to use the calibrated voltmeter and
resistance.
(11) Menu N: Loop Test Setting items
Menu N contains items that are relevant to loop
testing.
[N10: Test Mode] Setting for loop test execution
Setting Function
Normal No execution of loop testing.
Test Loop testing is started
IMPORTANT
(1) Test output has priority over flow rate
measurement signals. When carrying out flow
rate measurements, be sure to always return
to “Normal.”
(2) Upon entry to the Test Mode, current
output, totalization and DO terminal will
simultaneously adopt test condition.
(3) “Normal” will be restored when the power is
turned off or when the time set at N15: Test
Time have elapsed since the last operation in
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.
[N12: Test DO] Setting for DO terminal condition
during testing
This parameter sets the condition of the DO
terminal during loop testing. Setting is possible
when “Test” has been selected for N10: Test Mode.
Setting Function
Open (Off) DO terminal in Open (Off) condition
Closed (On) DO terminal in Closed (On) condition
Pulse
Outputs pulses as were specified with Menu E.*
*: If the pulse scale is 0 pps or there is a pulse setting error, the
DO terminal is “Open (Off).”
