Press the OPTION soft key to enable or disable the multi-interval option. If
you enable the multi-interval option, the division size you choose under
CAPAC applies to weight on the scale from 0 to ½ capacity. For weight on
the scale from ½ capacity to full capacity the division size will double.
When multi-interval is enabled, the division used to check for stability, center
of zero, and AZT is always the smaller division size. Overload and underload
is always calculated based on the upper division size.
The displaying and printing division size depends on which interval the scale
is in. The active interval is chosen based on net when a tare weight is active,
and gross weight when a tare is not active.
When gross is displayed or printed (regardless of the tare value) the division
size used depends on the interval used.
After pressing ENTER to accept your choice of enabling or disabling the
multi-interval option, the display returns to the SETUP soft key choices.
Press the CAL soft key to access the softkey set used to set zero and span,
shown below:
ZERO Use this key to set the zero reference.
SPAN Use this key to span the scale.
SPEC Use this key to access another set of soft keys for specialized
calibration.
Following are detailed instructions for setting these parameters.
If you press the ZERO soft key the display asks you to remove all weight
from the scale then press ENTER. After the indicator has calibrated the zero
point, the display says DONE and asks you to press any key. Above the text
you will see the weight displayed. It should read zero in the increments
you've chosen. If not you should perform this step again. The display returns
to the CAL display.
If you press the SPAN soft key, follow these instructions:
1. The current span calibration
weight is displayed. Press
ENTER to accept this weight or
key in a new one and press
ENTER. . .
2. Apply the test weight load to the
scale and press ENTER. . .
3. Press any key to return to the
CAL display.
The display prompts you to apply the
test weight load to the scale.
The indicator determines the span
and tells you when it is done. Above
the text, the display should show you
the correct test weight. If not perform
the span again.
