CALIBRATION
Mount the external sensor securely in a manner appropriate for its load
application. Select the calibration sub-menu in the configuration mode, as
described in the previous section, by pressing ENTER three times when the
display shows 'CAL'. After the display shows 'null' press ZERO, while ensuring
that the sensor is not loaded. The next displayed prompt is 'SPAn'. At this time,
apply the exact weight equal to the
full capacity of the sensor in English
units (i.e. model STJ50: 50 lbin, model SS1000: 1000 lb)
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, or an overloaded sensor. The calibration
procedure may be aborted without changing the previous calibration information
at any time by pressing ESCAPE.
