v Function Explanation:
q Total Flow Display Window: Displays present accumulated value and set value at setting
mode.
q Instantaneous Value Display Window: Displays the instant flow rate of input value.
q Explanation of Index Lamps:
HOLD: When External Input Control pauses the accumulation, the index lamp starts to blink.
ZERO : When Forced Zeroing is enabled, the index lamp will be turned on.
TEACH : When scaling setting inputs, the index lamp will be turned on. As the software starts
teaching function, the lamp starts to blink.
q Key Functions:
ESC
To switch parameter setting pages, cancel settings, or return to man display.
SET
To enter parameter setting or confirm setting.
To change value. Being pressed for 1 second can make the auxiliary display
window switch between set value or peak value.
To change currently set digit or change parameter directly.
