Maximum Initial Zero Setting Range

Parameter #
1285
Initial Zero Setting - The scale indication is set to zero automatically when the scanner is powered on, and before it is ready for use.
The default Initial Zero Setting range is set to -5% to +15% of the maximum capacity of the scale (i.e.: -1.5 lb to 4.5 lb, -0.75 kg to 2.25 kg).
When an object is left on the scale, and within this weight range at scale power up, it automatically zeroes the weight.
When the object is removed, the scale is in a negative weight condition, and an indication is present on the display (i.e.; dashes ------, or a blank display).
There are two ways to clear this condition, depending on the weight of the object that was initially on the scale.
  • After removal of a light weight object, the scale can be zeroed by touching the Zero button on the scanner front panel which zeros from -2% to 2% of the maximum capacity (i.e.: -0.6 lb to 0.6 lb, -0.3 kg to 0.3 kg). The allowable zeroing weight limit of 0.6 lb and 0.3 kg is configurable (see Maximum Scale Zeroing Weight Limit).
  • After removal of a heavy weighted object, the scale can only be zeroed by power cycling the scanner to reset the scale. (Ensure no objects remain on the scale. If so, remove and reapply power.)
This parameter allows a user to reduce the overall range of Initial Zero Setting by scanning a parameter which adjusts the positive limit from 2% to 15% in 1% increments. In addition, this parameter is intended to compensate for scale life time drift.
  • Higher values may cause the scale to fail more frequently at power on, making removal of the item from the platter and rebooting necessary.
  • Lower values may require more frequent scale calibrations.
If you frequently leave items on the platter during periods of non-use (like a cash drawer) you should set this value to 2 (0.9lb or 0.45kg). This prevents the need to reboot the scanner due to exceeding this maximum power on weight limit (see Parameter Value Settings).
For example, if the maximum initial zero setting range is programmed for +2% then if a weight greater 2% (i.e.: 0.6 lb, 0.3 kg) is left on the weighing surface at power up and then removed, the scale automatically finds zero with no intervention required by the user. In most all scenarios, a user would only want to program this setting for +2%, or leave the default setting of +15%.
A lower setting may result in more frequent legal scale calibrations.
Regardless of this parameter value, items above 4.5 lb or 2.25 kg also cause a u13 7-segment display message, but in this case the user can simply remove the items to clear the fault. A power cycle is not required.

, followed by two numeric barcodes from Numeric Barcodes, that correspond to the desired percent (e.g., 2% = 02, 3% = 03, 4% = 04, 10% = 10, 15% = 15). The range is 2% to 15% (i.e.: 02 to 15). The default setting is 15% maximum weight capacity (i.e., 4.5 lb, 2.25 kg).
