53) Lock Reset - Select YES to protect the RESET key from unauthorized use.
54) Lock Code - A Lock Code can be entered to prevent unauthorized personnel from
entering any of the Parameter Menus. This feature, combined with the key locks above, give a
high level of security to the WP20. When a Lock Code is entered, an ENTER LOCK CODE
message appears in the MODE window, presenting an opportunity to enter the code. Once the
Parameter menu has been accessed, all the menus can be entered without re-entering the code
until the EXIT key is pressed. 00000 disables the Lock Code, which is also the default setting,
and no buttons are then locked out
55) ASC - After the WP20 calculates the RATE, it multiplies that number by the ASC (Auto
Span Correction) factor before displaying it in the RATE window. In an ideal setup, ASC would
remain 1.000 which means that no correction is being made to the RATE. However, every
system requires some tuning. After calibrating the scale (discussed in section 7) the ASC value
can be increased or decreased manually to fine tune the displayed RATE, or you can do a
material test (Section 7.05) and the proper ASC value will be computed automatically. For
example, if the tested material weight ends up being 1.06 times the WP20 total, the ASC value
will be changed to 1.06 times the previous ASC value. From that point on, the WP20 will
calculate the RATE and then multiply it by the new ASC before displaying it. Note that the
typical range of values for ASC should be between 0.900 and 1.100. If the system requires an
ASC value outside this range, consult trouble shooting Section 9.04 (Scale is inaccurate section).
56) Span Detect: - During an AUTO SPAN, the processor waits for a change in the load cell
signal before initiating the procedure. This Parameter represents that change in load cell signal
that is a requirement to start the AUTO SPAN procedure. The factory setting should be adequate
unless a calibration weight change is made in the field. As a reference, this Parameter entry
should be approximately 70% of the total change in Load Counts between the calibration weight
being up and down.
57) Load Count - For technical trouble shooting purposes, the WP20 can display raw counts
from the weight sensors (load cells or LVDTs). The counts with the calibration weight up should
be low, and the counts with the calibration weight down should be high. The raw counts with the
calibration weight lifted, compared to the Zero Counts, indicates if the scale is in calibration. The
low/high range varies from system to system, but it should be consistent from day to day for the
same system. This value is mainly used when consulting with the
Tecweigh Service Department
(Section 2.01).
58) Zero Counts: - This Parameter is not editable. For technical trouble shooting purposes,
this Parameter displays the Load Counts that the processor is using as a zero reference. This
viewable Parameter is calculated during the Auto Zero procedure. It is mainly used when
consulting with the
Tecweigh Service Department (Section 2.01).
59) Span Counts: - This Parameter is not editable. For technical trouble shooting purposes,
this Parameter displays the Load Counts that the processor is using as a span reference. This
viewable Parameter is calculated during the Auto Span procedure. This value is mainly used
when consulting with the
Tecweigh Service Department (Section 2.01).
