Scale Interval
D:
The lowest scale interval d indicates
the weighing instrument’s resolution.
The scale intervals possible are: 1, 2,
5, 10, 20, 50, etc. If you have
selected the “trade” setting with
accuracy class l or m, the lowest
scale interval is not prompted because
it is equal to the verification scale
interval.
Verification Scale Interval
E:
The smallest verification scale interval
e indicates the resolution of this
weighing instrument in legal metrology.
With accuracy class l or m, the
verification scale interval e is the
same as the scale interval d. Thus
with classes l and m, the lowest
scale interval d is not prompted.
Minimum Capacity
Min. cap.:
The minimum capacity indicates the
minimum weight with which a
weighing instrument may be used in
legal metrology (legal-for-trade use).
The minimum capacity for weighing
instruments of accuracy class l is
20e, and for class m, 10e.
Note: Minimum capacity limits have
the function of warning the equipment
operator that loads below these limits
lead to cumulative addition of toleran-
ces, which can result in significant
errors of measurement. In Germany,
for example, weighing below the
minimum capacity is not permitted.
Range 1, Range 2,
Range 3:
Enter the limits for each range.
When a given limit is exceeded,
the accuracy changes.
The following applies for all limits:
Range 1 ≤ Range 2 ≤
Range 3 ≤ Max. cap.
Thus you can divide the weighing
range into 4 ranges. The display
resolution changes in intervals of 1,
2, 5, 10, 20, 50, etc. The lowest
resolution is the lowest scale
interval d. Ranges you do not
require should be set to 0.
Maximum capacity
Max. cap.:
The maximum capacity is the
maximum load that may be placed
on the weighing instrument. If the
weight exceeds this capacity, the
weighing instrument will display
H.
The scale intervals are calculated
from the maximum capacity and the
lowest scale interval d. In legal
metrology, the value of the scale
intervals in a multiple range weighing
instrument may attain up to 6000e
per range. In the »standard«
weighing mode, as opposed to
»trade«, you can define a
“SuperRange” to increase the
permitted intervals. For example, a
maximum capacity of 60.000 kg
combined with a smallest interval d of
0.001 kg yields 60,000 scale
intervals. These parameters,
however, may be influenced by
physical limitations.
Lock units:
With this function, you can make
particular weighing units inaccessible
during weighing (e.g., for legal
metrology). Accessible units are
marked by “*” in the display.
Calibration/Adjustment
Unit
:
The calibration unit defines the weight
unit with which calibration must be
performed. This unit will be used
even if a different unit has been
selected for the weighing mode.
Adjustment without
weights
:
The parameters for nominal capacity
in kg (specification of the strain-
gauge beam), resolution in kg and
sensitivity in mV/V are converted to
internal quantities. Once the A/D
converter configuration data has
been stored, these parameters can
no longer be read out.
Save data:
Save the configuration settings and
exit the menu.
Once these parameters have been
configured, the A/D converter in
conjunction with the weighing cell 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.
Important Note:
Please do not forget to relock the
menu access switch when you have
finished configuring the A/D
converter.
In addition, the weight unit must be
defined and the weighing platform
adjusted (calibration, adjustment and
linearization). For detailed
instructions, see the next section:
“Adjustments in Service Mode”.
Weighing results can no longer be
influenced by the industrial terminal
after the A/D converter has been
configured. The range of available
weighing instrument functions is
defined in the A/D converter. The
following functions, for example,
can be activated:
– Read weighing results
– Display metrological data
– Tare
– Calibrate/adjust
– Read tare value
– Save/delete tare input
