Calibration
82 W-4510 Weigh Scale Technical Reference Manual
Process calibration
Calibration establishes reference points that relate the detector output to actual (or known)
values of the process. When you first receive the scale there is no calibration and the sensor
does not read the weight.
There are three different types of calibrations:
1.
Channel #1 Initial Cal—Perform an initial calibration with a static load to get a close
calibration (this is not an easily reproducible calibration)
2.
Channel #1 Periodic Cal—This is a quick and reproducible calibration. It always ends
with the same calibration, without moving the product around
3.
Channel #2 Cal.
Calibration main menus
All of the calibration functions for the gauge are available under the Cal Menu.

The product code groups together a set of parameters that are associated with a unique
product. There are nine Product codes available for use.
Product codes 0 through 8 are available for Channel #1 that handles the process sensor
input, and product code 9 is for Channel #2 that is for optional sensor input.
You can view Product Code Tables from access level 0, however, access level 1 enables you
to setup or change values in the table. The table in Appendix 1 lists the set of 25 parameters.
Procedures for changing the product code screen are available on page 66 of this manual.
