LINEARITY VERIFICATION SETUP
If you are using a MAX
®
4000XL, linearity
verification can be performed if desired.
With a few exceptions for certain
industries, this feature is not generally
used. This screen allows recording of the
weight kit information for the weight kit
that will be used for the linearity
verification.
The following options are available:
•
ENABLE REPORTING – When enabled, the linearity verification results are added to
the BALANCE CALIBRATION REPORT.
•
SN – Serial Number for the weight kit.
•
CERT DATE – Certification date of the weight kit.
•
SIZE – Individual size of the weights in the kit. All weights must be the same size if
NIST Class F weights are used. If ASTM Class 1 or 2 weights are used, then a
combination of different sized weights can be used to create equal weight increments.
See the examples below for clarification.
•
COUNT – The number of weight increments.
Depending on your specific needs, the linearity of the balance can be verified across the
full range of the balance to 40 grams or across any smaller range, such as from 0 to 2
grams or 0 to 10 grams. The range to be verified and the weights to be used will
determine the SIZE and COUNT values to be input.
For example,
•
To verify the linearity across the range 0 to 10 grams, using 5 2g weights, SIZE
would be 2g and COUNT would be 5.
•
ASTM Class 2 weights of 5g, 10g, and 20g can be used to create equal weight
increments of 5g from 0g to 35g, allowing linearity verification of the range from 0
to 35 grams. In this case, SIZE is 5g and COUNT is 7 since 5g x 7 = 35g. During
the verification, the MAX
®
4000XL will prompt for:
o
1 x 5g – use the 5g weight,
o
2 x 5g – use the 10g weight,
o
3 x 5g – use the 5g and the 10g weight
o
4 x 5g – use the 20g weight.
Continue in this manner until all three weights are used for 7 x 5g at 35 grams.
