YOKOGAWA ATK4A-00 terminal

Auto Tare The IND780 can be configured so that tare is automatically taken (auto tare) after the weight on the scale exceeds a programmed tare threshold weight. Auto tare can be configured in Setup as enabled or disabled. When auto tare is enabled, the display changes to a zero net weight indication after the weight exceeds the threshold value. The previous weight on the scale is stored in the Alibi Table as the tare value. Auto tare operations involve: • Tare Threshold Weight—When weight on the scale platform exceeds the tare threshold value, and there is no motion, the terminal automatically tares. • Reset Threshold Weight—The reset threshold weight must be less than the tare threshold weight. When the weight on the scale platform falls below the reset threshold value, such as when a load has been removed, the terminal automatically resets the auto tare trigger. • Motion Check—A motion check is provided to control the re-arming of the auto tare function. If disabled, the auto tare trigger will be reset as soon as the weight falls below the reset value. If enabled, the weight must settle to nomotion below the reset threshold before the next auto tare can be initiated

Several conditions could inhibit the auto tare function: • Motion—Auto tare cannot be taken when the scale is in motion. If motion is detected after the weight on the scale exceeds a preset tare threshold weight, the IND780 will wait for a no-motion condition. If a stable (no motion) weight condition occurs within three seconds, the auto tare command is executed. • Auto Tare Disabled—Auto tare can be configured in Setup as enabled or disabled.

Clearing Tare

 Tare values can be cleared manually or automatically. Manual Clear Manually clear tare values by pressing the CLEAR key on the numeric keypad when the IND780 is in the net mode and has completed the weighing operation. Motion on the scale will not impact a manual clear. If configured in Setup, pressing the ZERO scale function key will first clear the tare before issuing a zero command (see the IND780 Technical Manual, Chapter 3.0, Configuration, the Scale section, Auto Clear). Auto Clear The IND780 can be configured to automatically clear tare when the weight returns to a value below a programmable threshold or by the print command. Once the tare is cleared, the display returns to the gross weighing mode. Auto clear is disabled or enabled in Setup. If auto clear is enabled, the following parameters as configured in Setup affect the auto clear operation: • Clear Threshold Weight—The clear threshold weight is the gross weight value below which the IND780 will automatically clear a tare after settling to a value. • Motion Check—A motion check is provided to control the automatic clearing of tare. If the motion check is disabled, the tare value is cleared as soon as the weight drops below the threshold weight (auto clear threshold), regardless of the motion status. If Auto Clear and Motion Check are enabled in the Tare Auto Clear screen, once the Auto Clear Threshold Weight value is passed and the then weight falls below the threshold (i.e. a load to be weighed is placed on the scale and then removed), the IND780 will wait for a no-motion condition then automatically clear the tare.
