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coefcient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coefcientvaluedirectly.

[M15: Flow Span Adjust] Setting of adjustment

factorofowspan

Thisparameterisusedtosettheadjustmentofow

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owrate

measurementsignals.Whencarryingoutow

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/

everseow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speciedwithMenuE.*

*: If the pulse scale is 0 pps or there is a pulse setting error, the

DO terminal is “Open (Off).”
