Linearity Adjustment
To satisfy linearity specifications, calculate the coefficient for correcting hardware linearity errors.
The operation procedure is as shown below.
(1) In the AD value display, press the [MENU] key several times to display "LINEAR," and then press the [O/T]
key.
(2) Press either the [MENU] or [UNIT] key to display "L. ADJUST," and then press the [O/T] key.
(3) "START" is displayed. Press the [O/T] key.
(4) Use the LCD weight value display to position the weight, and
after the stability mark light goes on
, press
the [O/T] key, and perform measurements of the adjustment data.
Example of weight value display:
Flashing
(5) When measurement of all adjustment data is complete, calculate the correction coefficient, and save in
NVRAM.
In addition, save the correction coefficient in Flash memory as a backup.
(6) Return to the AD value display.
