Scale parameters and functions
8.3 DR 3 Calibration parameters
SIWAREX WP251
Manual, 12/2015, A5E37203357A

8.3.5
Code for regulations
If the parameter is set to "OIML", WP251 performs a check to determine whether the entered
parameters conform to the requirements of the OIML Recommendation. For scales not
requiring official calibration, the parameter can be left deactivated (no check).
8.3.6
Minimum weighing range
For scales requiring official calibration, logging is not permitted below the minimum weighing
range. The minimum weighing range is specified in the unit "d" (numerical increments) for
verification.
The setting ex factory is 0 d and can thus be left for a scale not requiring official calibration.
For scales requiring official calibration, "20" is generally entered.
8.3.7
Maximum weighing range
For scales requiring official calibration, further logging is not permitted above the maximum
weighing range (+9d). The maximum weighing range is specified in weight unit for calibration
acceptance.
The maximum weighing range depends on the number and type of load cells used, and for
scales requiring official calibration additionally on the scale interval and the resulting
resolution of the scale.
For scales not requiring official calibration, the maximum weighing range corresponds to the
nominal load of all load cells (number of cells multiplied by the nominal load of one cell)
minus the dead load (mechanical setup).
The correct parameter assignment is important because various zero setting and taring limits
are specified as a percentage of it.
8.3.8
Calibration weights 0, 1, 2 and calibration digits 0, 1, 2
The calibration weights with the associated calibration digits define the scale characteristic.
A detailed description of this can be found in section "Calibration procedure" (page 73).
The calibration weights must be specified in ascending order. Normally, it is sufficient to
calibrate the scale with two calibration points (0 and 1). The setting of a third interpolation
point (calibration weight 2) is thus optional.
Typically, calibration weight 0 = 0, because the calibration point 0 is normally set with the
scale empty.
If a scale has been modified and the current content is known, this value can be entered and
set as the calibration weight. A larger calibration weight 1 is then specified and set.
