  • Page 19 SETTING WITH THE 16-DIGIT THUMBWHEEL SWITCH (SPF - 01 = 2) This method assigns an exclusive thumbwheel switch to each setpoint. Some setpoints are set with the front panel keys without using the thumbwheel switch. Assignment of the thumbwheel switch and the front panel keys differs depending on the weighing mode (CALF-14) Since the setpoint assigned to the thumbwheel switch is read in real time, it can be referred to by key operation, but it cannot be altered.

  • Page 53: Comparison Weight

    7-6 COMPARISON WEIGHT Although the weight compared with the setpoint is mainly the net, the gross is partially compared. Since the net assumes a negative value in loss-in-weight, setpoint is made with the polarity reversed. Setpoint of the weight with the setpoint allows you to select the display count and internal count. One graduation of the weight value appearing in the display section is the minimum graduation set with CALF-03.

    7-9 AUTOMATIC FREE FALL COMPENSATION Automatic free fall compensation is the capability to reduce a loading error in batch weighing. The following two kinds can be selected depending on the functioning of the automatic free fall compensation (SQF-03). 1) Automatically setting the “moving average of the last four actual free falls” as the free fall for the next weighing.

  • Page 59: Standard Serial Output (Ser. Out)

    8-3 STANDARD SERIAL OUTPUT (SER. OUT) The standard serial output is a 20 mA current loop. It is located on the rear panel of the indicator, and is used to connect a remote indicator or printer. This output does not have a power supply. Therefore, the external unit must supply the power.
