2.3.3 Span Calibration
[
SpaN
]
Span calibration uses one point. The span calibration point is established with a calibration mass placed on
the scale.
Note: Span calibration should be performed after zero calibration.
Calibration procedures:
1. Long press the Menu button until you see
mM.E.N.U
.
2. Release the button and wait for the display to show
C.A.L
. Press the Yes button.
3. Short press the No button to navigate until you see
SPAN
.
Press the Yes button.
4. The calibration point and the unit are flashing on the display based on the scale capacity and unit set in
the menu. (e.g.
030.000
kg) If you do not need to change the calibration point, skip to step 6.
5. To change the calibration point:
a)
Short press the No button several times until the desired number appears.
Note : press the Back button can decrease the digit.
b) Short press the Yes button to accept the number and move on to the next digit.
c) Repeat the process until all the digits are correct.
d) Press the Yes button to accept calibration point. It is flashing on the display.
6. Place a calibration mass of the specified weight on the pan and press the Yes button.
7. The display shows
--C--
, and then
-DONE-
when the calibration is finished.
8. Then the display shows
Lin
. Press the Exit button to exit.
Note:
