CCW-R-2**B INSTRUCTION MANUAL 6 FUNCTIONS OF THE OPERATION SCREENS

* The weighing time means the minimum time that a weigh head can participate in combination
weighing.
Even if interlock signals are input at a shorter interval than the weighing time shown in “Table 6-68 Filter
Number List”, the head cannot participate in weighing every time. The weighing time in “Table 6-68
Filter Number List” is based on the calculation below.
(Weighing time)
= (WH - PH delay time) + (Combination weighing time) + (Stable time) + (Filtering time)
= 130+20+360+(Filtering time)
4 [Stable Count] key Sets the number of times to check the stable judgment weight from the
[Numeric Keypad] screen.
5 [Auto Zero Tolerance] key Sets the tolerance weight to cause no zero error from the [Numeric Keypad]
screen.
The auto zero tolerance value can be set in increments of 0.1g.
6 [Auto Zero Interval] key Sets the interval of auto zero correction from the [Numeric Keypad] screen.
The auto zero interval is set to “5” in normal operation.
If the auto zero interval is set to “0”, no auto zero correction is performed.
7 [Filter No.] drop-down key Sets the digital filter number.
In selecting the filter, consider the cut-off frequency and the weighing time.
If a lower cut-off frequency value is set, influence of vibration decreases but
the weighing time increases, resulting in lower weighing speed.
In selecting the filter number, refer to “Table 6-68 Filter Number List”.
8 [AFV] radio button Selects [Off] or [Auto] on the AFV function for each filter number.
Sets up each item for Filter 0 - Filter 4. (Only for the models with the function)
9 [Output] key Outputs the set information to a printer or as a file.
