4.11.6. How to validate the test mode (simulated flow rate output)
Description
z Checks different outputs (LCD indication, analog output, DO output) upon simulating
flow rate outputs.
With the output at the actuated time as an initial value, the output changes up to the
input value (simulated flow rate target value) in a selected TRACKING TIME, and at
the input value, the output value becomes constant.
So long as the test mode is valid, "T" blinks on the left end of the 1st line of LCD on
the measurement mode screen.
Setting content
TEST MODE
: Enables or disables the test mode.
INPUT DATA
: Simulated flow rate target (percentage of MV full scale).
TRACKING TIME
: Time required to attain the simulated flow rate target
(above input value).
Settable range
TEST MODE validation : SETTING (valid), NOT USED (invalid)
INPUT DATA
: ±120%
TRACKING TIME
: 0 to 999 seconds
* For setting TRACKING TIME, 0sec is set to the damping (See 4.9.5).
z By performing the operation, the output of analog outputs, DO1, DO2, and DO3, varies depending on the setting.
Check beforehand whether each output can be changed or not.
z Be sure to resume "NOT USED" after the end of test.
Otherwise, the input value output status will be held until power is turned off.
z If “START/RESET” is selected as TOTAL MODE, the total value also changes. Select “STOP” to prevent the total value
change.
For actual keying, refer to the typical operation indicated below. Set the parameter protection to OFF beforehand. (See Section 4.4.1.)
Operation
(example)
Set the simulated flow rate target to 100%, and the tracking time to 100 [s].
