PARAMETER
EXPLANATION
Setup Number - Enter a parameter number on the numeric keypad and press
the PRINT key to jump directly to that parameter. This feature can be operated
at any time (while in parameter setup) by pressing the COUNT key.
1.
Scale Setup Configuration and Calibration - See the "Calibration Setup"
section for more details.
2.
Quick Scale Calibration and Fine Span Adjust - See the "Quick
calibration" section for more details.
3.
Minimum allowable piece count sample loading - The value entered for this
parameter is the percentage of the full scale weight required for the ADD lamp
to remain off. The higher this value, the greater the number of samples that
will have to be added to accept the sample as sufficient and turn off the ADD
lamp. The greater the number of samples used, the more accurate the count.
Use as high a value as feasible for your application.
4.
Automatic Zero Tracking - Zero tracking automatically zeros the scale
once per second if the weight is less than 1/4 graduations from current zero.
This feature is used to correct zero errors due to load cell drift, temperature
changes, or deadload drift(dust,evaporation,etc.). Zero tracking should be set
on for most applications where the APW is greater than .2 display graduations.
5. Digital
Averaging - Digital averaging is used to "smooth out" the
displayed reading. The XC780 is a very sensitive instrument, which can be
affected by vibration or air currents which cannot be felt be the operator.
Increasing digital averaging will stabilize the weight reading if mechanical
vibration is present. Decreasing digital averaging will allow the XC780 to
respond faster to changes in load. Use lower values for fast filling
operations.
6. Units
of
Weight - Select the units(pounds, kilograms, or grams) that will
be displayed or the XC780 main display. The corresponding annunciator lamp
will light. If the units are changed after calibration, the scale capacity
will remain exactly the same while the graduation size will be rounded to the
nearest multiple of 1,2, or 5. The XC780 does not require re-calibration if
the units are changed.
7. Motion
Band
Width - Motion band is used to set how stable the scale must
be to sample. The value is a fraction of one graduation. The actual motion
on the scale must be less than this fraction to allow the scale to sample.
Lower values of motion band will give more accurate counts, while higher values
allow for scale vibration. Use 0.02 to start and go up if counting takes too
long to clear.
8. Sample
Select - This parameter is used to allow the operator to enter any
random sample size, or require the operator to use a fixed number of samples
only(as set by the "SAMP " parameter). Select F(alse) to chose only fixed
