Evaluating the Test Results:
Calculate Xi for all of the three displayed values you wrote down
Xi = displayed value Gi - conventional mass W
Write down the calculated test values on the Balance Test Record.
Calculate the value X4 for all of the three displayed values you wrote down
Max. displayed value - min. displayed value
X4 = ———————————————————————
2
Write down the value X4 on the Balance Test Record.
Evaluation
The following conditions must be met:
1) At least two of the calculated values X1 to X3 must be less than or equal
to the sum SU.
2) X4 must be within the permissible tolerance of the span.
If these conditions are not met, you must proceed as follows:
Condition 1) is not met:
Adjust the internal linearity (with menu code >1 9 6<,) and repeat the test as
described in the section "Checking the Internal Span Adjustment".
After doing so, if the deviation is still more than SU, overwrite the internal
calibration / adjustment weight.
Condition 2) is not met:
Use a fine brush to clean the internal calibration / adjustment weight and
the areas on which the weights rest; but do not use a liquid.
Checking the Linearity
Check the linearity in increments.
The advantage of this test procedure is that the test and tare weights do not
have to be calibrated.
However, always make sure that you do not get the test weights mixed up
with the tare weights.
Test weights: (E2 - individual weights, nominal mass values)
Tare weights: (E2 - individual weights, nominal mass values)
