12.3. 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 “
poff
” or place something on the weighing pan to
disable the auto power-off function.
2. Refer to “12.1. Calibration mode” to enter
the calibration mode. The gravity
acceleration value is displayed.
3. Press the UNITS key and display “
Cal
”.
4. Press the TARE key. “
Cal 0
”
is displayed. Confirm
that nothing is placed on the weighing pan and wait for the
STABLE indicator to turn on.
5. Press the TARE key. 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)
When you enter with “kg” (“g”) or “pcs” mode, the value
is in “kg”. With “Ib” or “oz”, then “Ib”.
If you want to calibrate only the zero point without
calibrating SPAN, press the ZERO key.
After “
end
” is dislplayed, go to step 9.
6. To calibrate with a weight different from the
weighing capacity, change the displayed value
using the following keys.
UNITS To shift the digit that is blinking
to the right.
PRINT 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.
7. Place the calibration weight with the same value
as displayed on the weighing pan, and wait for
the STABLE indicator to turn on.
8. Press the TARE key. The scale calibrates SPAN and
“
end
” is displayed.
9. To finish the setting procedure, press the ZERO
1
key or
the CAL switch. The scale returns to the weighing mode.
Note: If the scale will be moved to another location, set the gravity acceleration
value for the new location and calibrate the scale according to the procedure
above. Refer to the previous section to set the gravity acceleration value.
