6. PARAMETERS
(8) Item J (TEST)
These items are for test of output.
A value in “( )” is the data corresponding to indicator.
[J10:OUT ANALOG] 4 to 20mA Current output.
This function allows you to select 4 to 20mA output for loop
test.
When this test is executed, transistor contact output (Pulse,
Alarm, Status) is fixed at ON or OFF (not determined).
Exiting this parameter item or stopping access after ten
minutes, this function will be reset automatically.
[J20:OUT PULSE] Pulse output
Output pulse output for loop test from 0Hz to 10000Hz.
Exiting this parameter item or stopping access after ten
minutes, this function will be reset automatically.
When this test is executed, current output is fixed at 0%
(4mA).
[J30:OUT STATUS] Status output test
Status output test can be executed (OFF(0) or ON(1)).
When this test is executed, current output is fixed at 0%
(4mA).
Exiting this parameter item or stopping access after ten
minutes, this function will be reset automatically.
[K26:N. B.RATIO] The ratio of Noise Balance.
When “NOISE BALANCE MODE (N. B. MODE)” is
“AUTO”, noise balance value is the indication only.
When N.B. mode is “MANUAL”, the noise balance can be
adjusted entering the setting values.
Note: Refer to “7.2 Adjustment for Manual Mode”.
[K30:VELOCITY] Flow velocity
Indication of flow velocity at the operating conditions.
[K32:SPAN V] Flow span velocity
Indication of flow span velocity.
When /MV is selected and “F10 : FUNCTION” is “Saturated
Steam” or “Superheat Steam” and “GAS : STD/Normal” or
“LIQUID : Mass”, the display of span velocity may differ
from an actual value.
[K34:VORTEX FREQ.] Vortex frequency.
Indication of voltex frequency at operating conditions.
[K36:SPAN F] Span vortex frequency.
Indication of span vortex frequency.
When /MV is selected and “F10 : FUNCTION” is “Saturated
Steam” or “Superheat Steam” and “GAS : STD/Normal” or
“LIQUID : Mass”, the display of span frequency may differ
from an actual value.
[K40:ERROR RECORD] Error record
The error record can be indicated.
• The error is recorded as history.
• The error history is not time-series data.
• The error history can be holded for 30 days.
In order to clear an error record, set the video inverse bar by
“< >” and press “ENTER”key twice.
[K50:SOFTWARE REV] Software revision
The software revision can be indicated.
(9) Item K (Maintenance)
These items are for maintenance.
A value in “( )” is the data corresponding to indicator.
[K10:TLA] TLA Adjustment
Trigger level (TLA) is adjusted upon shipment. Therefore,
TLA adjustment is nonnecessity. But set TLA adjustment
below as
• The measurement of Low flow rate area is required.
• Mechanical vibration and impact are applied to YEWFLO
and Zero point and low flow rate area is output.
Note: Refer to “7.2 Adjustment for Manual Mode”.
[K20:SIGNAL LEVEL]
Set the signal level.
[K25:N. B. MODE]
Set the Noise Balance Mode from “AUTO(0)” or
“MANUAL(1)” or “TUNING AT ZERO(2)”
