Loop check of output signal
Introduction
The converter is provided with a function of a constant current generator. As the magnitude of
a current that can be generated, an arbitrary value of 0 to 100% of the flow rate signal can be
set. A loop check can be made using this function.
Used when
Use this function to check the connection status or the operation of devices connected to the
converter in the measured loop.
Operation
This function is operated from the SFC. Use the following procedure.
Step Key Procedure SFC screen
1
CLR
( No )
Make sure that the SFC is set to
“READY”.
If a screen other than the one as shown
on the right is displayed,
press the

3 Press numeric keys to enter the value of
a signal current to be generated in
percentage.
The example to the right shows a case
where a current equivalent to 25% flow
rate is generated.

ENTER
( Yes )
NON-VOL
Press the
ENTER
( Yes )
NON-VOL
key.
This generates a constant current output
from the converter. A “#” mark is
displayed on the screen during the
output.

INPUT
CLR
( No )
To cancel the constant current output,
press
OUT- J
PUT
INPUT
and then press the
CLR
( No )
key.
When the constant current output is
canceled, the “#” mark on the screen
disappears.
Be sure to perform this operation at the
end of the loop check.
However, even if the instrument is left
without performing this operation, the
current output is automatically canceled
after 10 minutes.
