5.2.5
DR3 - Limit Frequency
Defining the limit frequency is critically important for suppressing interference.
The "speed" of the scale's reaction to the change in the measured value is
determined by specifying the limit frequency.
A value of e.g. 2 Hz leads to a relatively quick scale reaction to a weight change,
a value of e.g. 0.5 Hz makes the scale "sluggish".
5.2.6
DR3 - Depth of Average Value Filters
The average value filter is used to settle the weight value against interference.
The weight value is based on the average of the n weight values that the
SIWAREX FTC calculates every 10 msec, e.g. if n=10, 10 values are used for
calculating the average value. Every 10 ms, the oldest value drops out of the
calculation and the newest is considered in the calculation.
5.2.7
DR3 - Scale Name
The name consists of a maximum of 10 characters and can be freely selected.
Note
The scale name can no longer be changed after official calibration.
5.2.8
DR3 - Number of Weight Ranges
SIWAREX FTC can be defined as a scale with one, two or three different
measurement ranges. Depending on the construction type certification, the
numeral step can be defined separately for every range. Normally, only one
measuring range is used in the force measurement and continuous weighing (belt
scale, bulk flow measurement device) operating modes.
5.2.9
DR3 - Scale Type
If the number of ranges is greater than one then the scale type can be defined as a
multi-range scale or a multi-resolution scale.
Information on the function of a multi-range- or multi-resolution-scale can be found
in EN 45 501.
Note
If only one range is defined then this entry is meaningless.
5.2.10 DR3 - Activate Zero Setting upon Switching On
The scale can be set to zero automatically by switching the supply voltage on.
On verifiable scales, a weight value of +/- 10% of the max. measurement range
can be set to zero on start-up.
