How to switch off PSC
(From mass display) Press [CAL] repeatedly till Weight symbol is blinking → Press [O/T]
(“- iEtAtP”is displayed with“i”blinking) → Press [CAL] repeatedly until“A”blinks →
Press [O/T] (“PSC on”is displayed) → Press [CAL] (“PSC off”is displayed) → Press [O/T]
(Stability mark ¨ ) is added) → Press [POWER] repeatedly to return to the mass display.
Press [POWER] key while Weight symbol is blinking.
When PSC is off, perform span calibration according to Span Calibration Procedure when it
is necessary. Clock-CAL is a practical alternative that performs regular automatic span calibration
according to time setting (UW series only, up to 3 times a day, refer to main manual 10.3.3).
Span Calibration Procedure
Calibration is required to accurately weigh items with an electronic balance.
Calibration should be performed:
x When the location of the balance is changed, even within the same room.
x When the room temperature changes considerably.
x 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.

(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.
