5−3−2. When the calibration is executed again.
When purchasing a new instrument and the combined inspection has executed at Minebea,
however, the tare weight has changed, or fine adjustment on zero and span are required, make
calibration with whichever the following methods.
(1) Calculation on tare weight only
(When combined inspection has completed at Minebea and calibration on only tare weight is
required.)
When the initial load (tare weight) has changed after completing the calibration, or when the
combined inspection at Minebea has been made and the calibration only for the initial
load(tare weight) is required after the installation, proceed the calibration in the following
steps.
1
After setting the initial load (tare weight) on load cell section, execute calibration according to
the paragraph 5−2−6.
(2) In case of executing fine adjustment on zero and span
Make adjustment according to the paragraph 5−2−4(Fine adjustment on zero), and 5−2−5
(Fine adjustment on span).
Warning ● The accuracy obtained through the calibration procedures consists
from combined accuracy with the instrument and strain gage applied
transducer, the accuracy of weight used during the calibration, error
factors on mechanical and also error factors on calibration works, that
is , total accuracy of these.
If high accuracy is required, full considerations should be made on
each factor. If neglected, there will be a case that the desired accuracy
shall not be obtained.
5−4. Setting the prohibition against calibration
After completing all of the calibration procedures, setting can be made to prohibit any more
calibration again by setting the funciton(Related function F−97).
For details, refer to the paragraph 7−17.
