4-3-6. Calibration of zero point
When the zero calibration starts, is displayed.
Please select the zero calibration method.
① Method by the measuring data (status of initial load)
Press the key, and execute the operation of a).
Execute the calibration of zero with nothing put on the measuring section.
② Method by the numeric input of the load cell output voltage.
Press the key, and execute the operation of b).
Execute the calibration of zero with inputting the output voltage value of the load cell when nothing is
put on the measuring section.
a) Method by the measuring data (status of initial load)
Please make that nothing is put on the measuring
section.
Press the key when display blinks,
and the MD mark lights on. The zero point 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 load cell output voltage in
mV/V scale
which correspond to the zero point of the measurement.
: 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
.
: The display value is memorized, and it
proceed to the next step.
After the setting, press the key.
Error display in the calibration of zero point
: The display blinks for about two seconds when the output of the load cell is -2.5 mV/V or less.
(Refer to the paragraph 16. Error display.)
：The display blinks for about two seconds when the output of the load cell is 2.5 mV/V or more.
(Refer to the paragraph 16. Error display.)
Press the

the measuring
section.
Move to the calibration of span.
