PRODUCTS
The 4200 has the ability to store information for 20 products (200 products if option 42
OPT 27 is installed). There is a separate tare, over, and under value associated with each
product. These values are saved in nonvolatile memory so that they are not lost if power is
removed. When a product is selected via the PROD button and the UP and DOWN
arrows, the tare, over, and under values associated with that product will become active.
This means that any tare operations or checkweighing operations will use the values for
that product. The values for the tare, over, and under values for each product must of
course be entered before performing any tare or checkweighing operations. These values
can be entered in a number of ways - see the explanations for these operations elsewhere
in this section.
To select a product to either use that product's values or to enter new values, first
momentarily press the PROD button. The indicator will display "Prd XX", where XX is the
number of the currently active product. Press the UP or DOWN arrow buttons to change to
a different product number. To activate the new product, press PROD again, and the
indicator will return to normal weighing. All tare and checkweighing operations will now use
the values entered for the product just selected.
ZERO OPERATION
The ZERO push-button is only active in the gross weight mode. When pressed, ZERO
causes the display to read zero; it operates on positive or negative weights.
There are 3 operating modes, "OP" for the ZERO function that are menu selectable:
Std
Standard mode which allows full range ZERO operation.
44
Handbook 44 mode which allows only +/- 1.9 % of scale capacity to be zeroed. CAn
Canada Weights and Measures mode which allows only +/- 4% of scale capacity
to be
zeroed.
As an example, for a 30 lb. capacity scale, you can zero up to the full 30.00 lb. when in the
"Std" mode, up to +/- 0.57 lb. (+/- 1.9 % of 30 lb.) in the "44" mode, and up to
+/- 1.20 lb. (+/- 4.0% of 30 lb.) in the "CAn" mode.
Please note that the startup zero reference point is set upon scale power-up. If any weight
is left on the scale upon power-up (or power failure restart) it will be auto-zeroed, setting
that weight as the overall gross zero reference point. If you are in the "44" or "CAn" mode,
you will not be able to zero any weight greater than +/- 1.9 % or +/- 4.0 % of capacity,
based on the gross zero previously set. To avoid potential problems, just be sure that the
scale is empty when power-up occurs. This sets the start up zero reference point to the
proper value.
