Maximum Initial Zero Setting Range (Parameter #1285)
In 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% (‑1.5 lb to 4.5 lb, ‑0.75 kg to 2.25 kg) of the maximum capacity of the scale.
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 (that is, 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 removing a light weight object, the scale can be zeroed by touching the Scale Zero button on the NCR 7895 front panel. This zeros from -2% to 2% (‑0.6 lb to 0.6 lb, ‑0.3 kg to 0.3 kg)of the maximum capacity of the scale. The allowable zeroing weight limit of 0.6 lb and 0.3 kg is configurable (refer to Maximum Scale Zeroing Weight Limit (Parameter #1366)).
- After removing a heavy weighted object, the scale can only be zeroed by power cycling the NCR 7895 to reset the scale.Note
Ensure no objects remain on the scale. If so, remove and reapply power.
This parameter allows users to reduce the overall range of Initial Zero Setting by scanning a parameter to adjust 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, requiring users to remove an item from the Top Plate and then reboot.
- Lower values may require more frequent scale calibrations.
If users frequently leave items on the Top Plate during periods of non‑use (like a cash drawer), set this value to 2 (0.9 lb, 0.45 kg). This prevents the need to reboot the NCR 7895 due to exceeding this maximum power on weight limit. For more information on values for this parameter, refer to the table included in this section.
For example, the maximum initial zero setting range is programmed for +2% and a weight greater than 2% (0.6 lb, 0.3 kg) is left on the weighing surface at power up and then removed. In this scenario, the scale automatically finds zero with no intervention required from users. In most scenarios, users would only want to program this setting for +2%, or leave the default setting of +15%.
To set this parameter, scan Set Scale Maximum Initial Zero Setting Range below, followed by two numeric bar codes from Numeric Bar Codes that correspond to the preferred percentage. The range is 2% to 15% (parameter value 02 to 15). By default, the setting is 15% maximum weight capacity (4.5 lb, 2.25 kg).
Enter a leading zero for single digit numbers.
To set 2%, scan the bar code below, and then scan the 0 and 2 bar codes. To correct an error or change the selection, scan the Cancel bar code in Numeric Bar Codes.
| Percentage | Parameter Value | Pound | Kilogram |
|---|---|---|---|
| 2% | 02 (minimum) | 0.6 | 0.30 |
| 3% | 03 | 0.9 | 0.45 |
| 4% | 04 | 1.2 | 0.60 |
| 5% | 05 | 1.5 | 0.75 |
| 6% | 06 | 1.8 | 0.90 |
| 7% | 07 | 2.1 | 1.05 |
| 8% | 08 | 2.4 | 1.20 |
| 9% | 09 | 2.7 | 1.35 |
| 10% | 10 | 3.0 | 1.50 |
| 11% | 11 | 3.3 | 1.65 |
| 12% | 12 | 3.6 | 1.80 |
| 13% | 13 | 3.9 | 1.95 |
| 14% | 14 | 4.2 | 2.10 |
| 15% | 15 (maximum, default) | 4.5 | 2.25 |
Take note of the following:
- 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.
