Scale interval d
Scale interval d indicates the resolution of the weighing instrument.
The scale interval d can be entered only in increments of 1, 2, 5, 10, 20, etc.
When using verifiable or verified weighing platforms, the scale interval d is the same as
the verification scale interval e.
Verification scale interval e
The verification scale interval e indicates the resolution of the weighing instrument in
legal metrology. The verification scale interval e can be entered only in increments of 1, 2,
5, 10, 20, etc. For weighing instruments of accuracy class l or m, e = d. This is why
the scale interval d does not need to be entered separately.
When “Standard configuration” is used, this menu item is not displayed.
Minimum capacity (min. cap.)
When “Standard configuration” is used, this menu item is not displayed. The minimum
load of the connected weighing platform is entered under this menu item.
The minimum load for scales of accuracy class l is 20 e and 10 e for class m.
Important Note: The function of the minimum load setting is to warn operators that
below this limit, the summation of tolerances might lead to significant measurement
errors. In Germany, for example, initial weights below the minimum load are not allowed.
Maximum capacity (Max. cap.)
The maximum capacity is the maximum load that may be placed on the weighing
instrument. When heavier weights are used the weighing instrument displays overload
“H.” The scale intervals of the weighing instrument are calculated using the maximum
load and the scale interval d (e.g. max. capacity = 15.000 kg, smallest scale interval
d = 0.005 kg yields 3000 scale intervals).
In legal metrology the total number of intervals must be no more than 3000 e, and when
using multi-interval scales there must not be more than 3000 e intervals per range.
In standard operation, as opposed to legal metrology, you can define a “Super Range”
weighing instrument of over 3000 intervals. These parameters, however, may be
influenced by physical restrictions.
Range 1, Range 2, Range 3
The range limits are entered for the individual ranges. The accuracy changes when these
limits are exceeded. The following applies when entering limits: range 1 < range 2
< range 3 < maximum capacity.
This means that the weighing range can be divided into a maximum of 4 ranges. The
resolution changes at intervals of 1, 2, 5, 10, 20 etc., where the lowest resolution is the
smallest scale interval entered. Set ranges that are not required for use to zero.
Available units
With this function, you can make particular weight units (weight unit x, x=1, 2)
inaccessible during weighing. Available units are indicated by a * on the display (more
than one can be selected).
To enable or disable a unit, select the unit by pressing the “
Q" or “q" soft key, and then
press the “l" soft key (toggle function).
Saving parameters
To save the ADC configuration, use the “
O" soft key to select “Yes" and confirm with
the “l" soft key. The device software is reset, and the scale returns to the normal
weighing mode. To exit the menu without saving configuration changes, press the “
o"
soft key.
Once these parameters have been configured, the A/D converter in conjunction with the
load cell(s) is defined as a weighing instrument. The A/D converter, in conjunction with
the weighing platform, can now be used like any standard weighing platform. In addition,
the weight unit must be defined and the weighing platform adjusted (calibration,
adjustment and linearization must be performed). For a detailed description of these
procedures, see the “Adjustment in Service Mode" section.
