6.7.10 Counting accuracy
You can influence the counting accuracy of your scale in setup mode in Program Settings /
Counting.
•
Standard reference quantity
The factory default for the reference quantity is 10.
This quantity can be specified between 1 and 99.
For small parts, it makes sense to use a larger quantity of parts to determine the reference
weight.
•
Minimum reference weight
The counting scale checks whether the total weight of the reference parts falls short of a
minimum reference weight. The basis of the calculation is the smallest number increment of
the scale multiplied by a value stored in setup mode. The factory default is a factor of 10,
e.g. 10 number increments. Values can range between 1 and 50.
The determined quantity is marked with a star in the display as information for the user if
the minimum reference weight is not met or when the calculated reference weight is
smaller than the number increment of the scale (the smallest number increment for multi-
range scales).
If a reference parts falls 10% short of the smallest number increment of the enabled scale,
the reference weight cannot be determined for these parts and
"Error 04 Reference Weight Tool Small" is shown in the display. These parts need to
counted by a scale
with a smaller number increment.
Example for a scale with 1 g number step:
Factory default is 10 d = 10 g for the total reference weight of the reference parts.
By reducing the factory default to 5 d, the scale accepts 5 g as the minimum weight for the
total weight of the reference parts. By increasing the factory default to 20 d, the scale
requires 20 g as the minimum weight for the total weight of the reference parts.
•
ADD Mode
If the minimum reference weight has not been met, the unit prompts for parts until the
minimum reference weight has been reached.. The scale calculates the reference weight
after the required parts have been placed (add xx units).
Example for determining the reference weight in ADD mode:
Smallest number increment of the scale:
1 g
Programmed minimum load:
10 d
Resulting minimum load for the determining the reference weight: 10 g
Example for the part weight:
0.8 g
Reference quantity:
10 pieces
Resulting weight reading for the determining the reference weight: 8 g
Difference to the programmed minimum load: 2 g
ADD mode requires more parts:
3 pieces
