３-２.Clibration procedures
３-２-１.Calibration by the actual load
Procedure1 Connect the instrument and
strain gage applied transducer.
Procedure2 To stabilize this unit and the measuring section
(loadcell), please make the instrument to
the status of energiging for about 20 min.
Procedure3 Set the strain gage applied transducer to the condition
at initial load (tare weight). When the initial load
(tare weight) is exceeding the ± 0.25 mV/V at the
input conversion, cancel the initial load (tare weight)
referring to the paragraph 3-3.
Adjust the output voltage value to 0.000 V with
“ ZERO" trimmer.
Procedure4 Put the rated load (pressure) on the strain gage applied
transducer, and adjusts the SPAN" trimmer to become
the output voltage value to be set.
Procedure5 After removing the standard weight set on step 3,
confirm the output voltage value to be at 0.000 V.
If not, return to the step 3.
Procedure6 Please complete from the calibration mode by actual
load.
