• when the displayed weight is inaccurate, even when the scale has a
correct zero.
• when the scale is unable to assume the initial zero point, even with an
empty platform.
Tip
• It is a good maintenance rule to check the calibration
routinely by placing a weight on the weighing platform to
verify that the Weight Display shows a steady and accurate
weight.
To calibrate the scale
1
Make sure the platform is empty.
2 Press the MENU and ZERO keys simultaneously to put
the scale in Cal Mode.

4 Place the reference weight on the platform.
5 Press the PRINT key to start the calibration.
The Weight Display shows
while the scale performs
the calibration.
6 When the calibration is completed, the message
(where
is a number between 0 and 99) appears on the
Weight Display.
Values above 25 indicate a poor calibration. In that case you
must repeat steps 1 to 4 above.
Note: The message appears when a marine scale
has been calibrated without the platform being in motion.
7 Remove the reference weight from the platform.
8 The Weight Display returns to zero and the scale is now
ready for use.
