5−3. Selection of calibration procedures on each condition
The instrument prepares calibration procedures shown in the paragraph in 5−2. Calibration
methods, here we’ll show some conditions to execute actual calibration.
(1) When executing calibration on the new instrument (In case that our combined inspection
has not executed.)
D When load condition and output condition of load cell are clarified. (Required accuracy is
less than 1/1 000 or so.)
D When load condition and output condition of load cell are clarified.(Required accuracy is
more than 1/1 000 or so.)
D When load condition is clarified, but output condition of load cell is unclear.
D When exchanging with existing CSD−581−15 is required.
(2) When making calibration again
DWhen calibration only for tare weight is required.(When our combined inspection
has already executed, and calibration only for tare weight is required.)
DWhen fine adjustment on zero and span is required.
5−3−1. In case of executing the calibration on new instrument.
When the new instrument is purchased or re−use is desired with the new specific conditions,
execute the calibration with whichever method as follows:
(1) When load condition and output condition of load cell are clarified.
(In case of desired accuracy is less than 1/1000 or so.)
Warning ● The calibration accuracy in this procedure is less than 1/1 000 or so.
When precise accuracy more than 1/1 000 is required, make
calibration with actual load according to the paragraph 5−3−1(2).
Besides, the accuracy described here is combined accuracy of the
instrument and the strain gage applied transducer to be connected
with. If there may exist another factors of error such as mechanical
elements and so on, it will become out of warranty, so care should be
taken fully.
● Rated output value for load cell applied on calculation should be the
same value are described on the “Inspection data” individually.
