4-3-7. Calibration of span
When the span calibration starts, is displayed.
Please select the span calibration method.
(1) Method by the measuring ⇒ data Press the 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 load cell output ⇒Press the key, and execute the
operation b).
Execute the span calibration by inputting the value which subtracts the output voltage of the load cell
to zero point of measurement set in paragraph 4-3-6. From the output voltage corresponding to the
mass of the weight set in paragraph 4-3-5.
a) Method with weight
Please put the weight corresponds to mass set
in the paragraph 4-3-5 on the measuring
section.
Please press the key when
display blinks, and the STABLE
mark lights. Span is memorized and
is displayed.
b) Method by the numeric input of load cell
output voltage.
When key is pressed, is
displayed, and when key is pressed,
is displayed also.
[ ] is the memorized output voltage
of the load cell. Please set the value in mV/V
scale which subtracts the output voltage of the
load cell to zero point of measurement from the
output voltage corresponding to the mass of the
weighing capacity.
: The value of changed digit is
changed.
: Changed digit is selected.
: The displayed value is changed to
zero.
: Setting is interrupted and display
returns to CCAL.
: The display value is memorized, and
it proceeds to the next step.
After the setting, press the key.
Error display in the calibration of span
: The display blinks for about two seconds when ([Load cell output voltage at span]－
[Load cell output voltage at zero point]) ≦ 0.0 mV/V.
(Refer to the paragraph 19. Error display)
: The display blinks for about two seconds when load cell output is 3.1 mV/V or more.
(Refer to the paragraph 19. Error display)
