INF-TN1FSC-E 123
(2) Analog output
It allows you to set the constant current output of analog
signal.
When setting the simulating output (test mode), each
output can be checked (LCD display, analog output).
With the output at the actuated time as an initial value,
the output changes up to the input value (simulated fl ow
rate target value) in a selected tracking time and, at the
input data, the analog output value becomes constant.
(1) Generate a fi xed value output; use when checking the
operation of a connected receiver and current output
circuit of the main unit.
Setting range: –20 to 120%
Move the cursor to ANALOG OUTPUT on the
CHECK screen and press the
ENT
key.
The cursor moves to ANALOG OUTPUT, prompting
you to set the constant current output value.
(2) When using the test mode to check for the measure-
ment status, move the cursor pointed to ANALOG
OUTPUT to TEST MODE and make the following
settings.
“TEST MODE”: USED/NOT USED
“INPUT DATA”: Simulated fl ow rate target (percent-
age of maximum fl ow rate).
“TRACKING TIME”: Time required to attain the
simulated fl ow rate target.
Setting range: Input data: 0 to ±120%
Tracking data: 0 to 900sec.
* For setting TRACKING TIME, 0sec is set to the
damping (See 10.1.4(4)).

• Be sure to return the setting to “NOT USED” after the
test is completed. Otherwise, the output will be held at
the input data value until power is turned off.
• For being started TOTAL, total value will also change.
• If you set the Thermal fl ow of “10.4.2(1) Type of Output
range”, test mode function will be disabled.
• When changing to the transit time difference on the
maintenance screen or the fl ow velocity profi le screen,
the test mode will be cancelled.
