11.3.Calibration Using A Weight
Prepare a weight, preferably a weight with the same value as the weighing capacity of the scale
to be calibrated. Note that the calibration weight value can be changed.
1. Turn the power ON and warm up the scale for at least half an hour.
 Change the function setting or place something on the weighing pan to disable
the auto power-off function.
2. Refer to "
Calibration Mode
" to enter the calibration mode.
The CAL is displayed.
3. Press the
TARE
switch, then is displayed.
Confirm that nothing is placed on the weighing pan and
wait for the STABLE indicator to turn on.
4. Press the
TARE
switch. The scale calibrates the zero
point and displays the value of the calibration weight
(SPAN calibration).
 The calibration weight value is equal to the weighing
capacity. (factory setting)
 If SPAN calibration is not to be performed, turn the power
OFF to exit from the calibration procedure.
5. To calibrate with a weight different from the weighing
capacity, change the displayed value using the
following switches.
MODE
To shift the digit that is blinking to the right.
SAMPLE
To increase the value of the blinking digit by one.
 Using a weight with the same value as the weighing
capacity is recommended. If other weights are used,
use one with a value greater than two-thirds of the
capacity.
6. Place the calibration weight with the same value as
displayed on the weighing pan, and wait for the STABLE
indicator to turn on.
7. Press the
TARE
switch. The scale calibrates SPAN and
is displayed. Then, the display returns to .
To finish the procedure, press and hold the
switch or press the
CAL
switch. The scale turns the
power OFF.
Note: If the scale will be moved to another location, set the gravity acceleration value
for the present location first and calibrate the scale using a weight. Then,
change the gravity acceleration value for the new location.
