Sample quantity
Quantity of a product sample
Error value [- T]
Value of negative permissible error
–T
, set in
a weighing unit determined for the product.
Measurements below the
Qn-T
value will
be comprehended as defective.
Error value [+ T]
Value of positive permissible error
+T
set in
a weighing unit determined for the product.
Measurements above the
Qn+T
value will
be comprehended as defective.
Quantity of disqualifying
samples [Qn – 2T]
Number of recorded negative errors
-2T
in
a tested sample that disqualifies a control
Quantity of disqualifying
samples [Qn + 2T]
Number of recorded positive errors
+2T
in
a tested sample that disqualifies a control
Quantity of disqualifying
samples [Qn – T]
Number of recorded negative errors
-T
in
a tested sample that disqualifies a control
Quantity of disqualifying
samples [Qn + T]
Number of recorded positive errors

in
a tested sample that disqualifies a control
Average limit value
Mode for calculating the average limit value
(constant or automatic)
Average limit value [ - ]
Average limit value (negative) for a tested
sample (refers to average limit value as a
“constant”)
Average limit value [ + ]
Average limit value (positive) for a tested
sample (refers to average limit value as a
“constant”)
Factor value [- Wk]
Standard deviation multiplier for the average
limit value (negative) determined in the
automatic mode
Factor value [+ Wk]
Standard deviation multiplier for the average
limit value (positive) determined in the
automatic mode
