Functions of the keys
*1 This key is used to set values when percent (%), number (PCS), solid specific gravity (
T
d), or liquid specific
gravity (d) are displayed.
*2 When a Pretare value is set, zero is not displayed and [- Pretare value] is displayed.
*3 Units other than “g” must be set up before they can be used for measurement. Only gram (g), percent (%), and
piece counting (PCS) are set-up before shipment. To set up other units or specific gravity measurement, refer
to section 12., or 14.1, 14.2.
*4 When the unit is set to 10d, the resolution of the minimum display is decreased by one decimal place.

Span Calibration Procedure
Calibration is required to accurately weigh items with an electronic balance.
Calibration should be performed:
• When the location of the balance is changed, even within the same room.
• When the room temperature changes considerably.
• Periodically, according to the quality control plan of the user.
Before span calibration, verify that the balance is in the mass-display and that the pan is empty.
UW series [Span Calibration Using the Built-in Weight]
(1) Press the
[CAL]
key once. “i-CAL” is displayed.
(2) Press the
[O/T]
key. After “i-CAL3”...“i-CAL1”, and “SEt”, “CAL End” are displayed indicating the
completion of span calibration, the mass-display will return.
* This is the calibration of default setting. Refer to 10.3.1 for the use of external weights.
UX series [Span Calibration Using External Weights]
(1) Press the
[CAL]
key once. “E-CAL” is displayed.
(2) Press the
[O/T]
key.
The value of the correct calibration weight to be loaded is displayed and blinks.
(3) Load the indicated calibration weight and press the
[O/T]
key.
(4) When the zero display blinks, unload the weight from the pan and press the
[O/T]
key. “SEt” is
displayed briefly to indicate completion of span calibration. Then the mass-display will return.
