4.10. Application operation of parameter
4.10.1. Setting automatic 2 ranges
Description
z The function carries out a measurement while changing over the range
according to the flow rate.
z The current output changes with the action range as illustrated on the right.
z The hysteresis can be set to between 0 and 20% of the smaller range.
z Upon setting DO1, DO2 or DO3 to "FULL SCALE 2", a contact outputs "FULL
SCALE 2" action. Select “ACTIVE ON” or “ACTIVE OFF” separately. (See
4.10.5.)
z Settable range: 0.3 to 32 [m/s]; 0.984 to 105 [ft/s] in terms of flow velocity for
FULL SCALE1 and FULL SCALE2.
* Preset PIPE PARAMETER and FLOW UNIT.
* If a value beyond the settable range is inputted, "INPUT ERROR" appears
and then last setting is resumed.
* If "FLOW UNIT" has been changed after setting the range, redo the range
setting.
* When FULL SCALE2 is not used (in the case of single range), set “0” to
FULL SCALE2.
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 “AUTO 2” to “RANGE TYPE”, 10[m
3
/h] to “FULL SCALE1”, and 60[m
3
/h] to “FULL SCALE2”.
Set “RANGE HYS.” to 7%.
* Preset “PIPE PARAMETER” and “FLOW UNIT”.
