4 - 20 MP6000 BAR CODE PROGRAMMING GUIDE

Maximum Initial Zero Setting Range

Parameter #1285

Initial Zero Setting - The scale indication is set to zero automatically when the device 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

MP6000 front panel which zeros from -2% to 2% of the maximum capacity (i.e.: -0.6 lb to 0.6 lb, -0.3kg to

0.3 kg).

•

After removal of a heavy weighted object, the scale can only be zeroed by power cycling the MP6000 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 require cause the MP6000 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 MP6000 due to exceeding this maximum

power on weight limit (see Table 4-2 on page 4-21).

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%.

Scan Set Scale Maximum Initial Zero Setting Range, followed by two numeric bar codes from Appendix D,

NUMERIC BAR CODES, 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).

NOTES 1,A lower setting may result in more frequent legal scale calibrations.

2.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.
