4-5-7. Calibration at span
When span calibration starts, is displayed. Please select span calibration method.
(1) Method by the measuring data  Press key, and execute the operation of a).
Execute the span calibration with weight put on the measuring section.
(2) Method by the numeric output of the digital load cell output count
 Press key, and execute the operation b).
Execute the span calibration by inputting the value which subtract the output count of the digital
load cell to zero point of measurement set in paragraph 4-5-6. from the digital load cell output count
corresponding to the mass of the counterweight set in paragraph 4-5-5.
a) Method with weight
Put the counterweight corresponds to mass set in the paragraph
4-5-5 on the measuring section.
Press key when display blinks, and STAB.
mark lights on. Span is memorized and is
displayed.
b) Method by the numeric input of digital load cell output count.
When key is pressed, is displayed, and when
key is pressed, is displayed also.
[ ] is memorized output count of a digital load cell. Set
the value in count scale which subtract the output count of the
digital load cell to zero point of measurement from the output
count of the digital load cell corresponding to the mass of the
counterweight.
[ ] is set the lower four count value.
[ ] is set the higher three count value.
: The value of changed digit is changed.
: Changed digit is selected.
: The displayed value is changed to [0].
: Setting is interrupted and display returns to
: Display value is memorized, and it proceed to next step.
After the setting, press key.
