CALIBRATION
Mount the gauge firmly with the loading shaft pointing downward. Go into the configu-
ration mode as described in the previous section and select the calibration sub-menu
by pressing ENTER three times when the display shows 'CAL'. After the display shows
'null' press ZERO, while insuring that there is no weight on the loading shaft other than
the weight of the required attachments (hooks, etc.). The next displayed prompt is
'SPAn' at which time apply the exact weight equal to the
full capacity of the gauge
in pounds
and press ENTER. A successful calibration procedure is indicated by 'donE'
on the display. Press ENTER to save the new calibration data and to return to normal
operation. In some cases the display will show 'nnnn' or 'uuuu' to indicate excessive or
insufficient calibration weight. This can be caused by incorrect weights, tare weight of
over 10% of the full capacity of the gauge or an overloaded sensor. The calibration
procedure may be aborted without changing the previous calibration information at
any time by pressing ESCAPE.
