When the load at the section of load cell can’t make it initial load application due to failure on
the existing CSD−581−15, execute calibration, execute calibration by referring to the
procedures as below. However, when initial load condition can be obtained, make
calibration according to the procedures of (1) and (2).
1
According to the paragraph 8−1, read and note the “Increment value” of Function F−70,
“Maximum display value” of F−71, “Zero calibration value” of F−73, and “Span calibration
value” of F−74.
2
According to the paragraph 4, replace the exiting CSD−581−15 with a normal product and
make connections.
3
After turning ON the normal instrument, make calibration according to the paragraph
5−2−2. At the same time, input each “Increment value” noted at ① in the step 3, “Maximum
display value” in the step 5 and “Zero calibration value” in the step 7 and in the same way,
input “Span calibration value” each.
5−3−2. In case of executing re−calibration
When purchasing the new instrument, and also executing our combined inspection,
Tare weight has changed, fine adjustment on zero and span are required, make calibration with
whichever method as follows:
(1) Calculation on tare weight only
（When
our combined inspection has completed and only calibration on tare weight is
required.)
Though calibration has completed, initial load (tare weight) has changed, or our combined
inspection is made and calibration only for the initial load(tare weight) is required
after installation, make calibration according to the following procedures.
1
After setting the initial load (tare weight) for 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 procedures of this calibration
consists from combined accuracy with the instrument and combined
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 factors. If
neglected, there will be a case that desired accuracy shall not be
obtained.
