Many parameters require an instance to be specified when accessing their values. For example, we can speak of the gross weight (P0). But suppose there are 4 scales enabled. Each scale has it’s own gross weight. Which gross weight are we speaking of?
In order to identify which instance of a parameter we wish to reference, we include the instance number immediately after the parameter number, separating both numbers with a decimal point. For example:
0.0P refers to the gross weight for the currently selected scale
0.1P refers to the gross weight for scale #1
0.2P refers to the gross weight for scale #2
0.3P refers to the gross weight for scale #3
0.4P refers to the gross weight for scale #4
0.5P refers to the gross weight for scale #5
0.6P refers to the gross weight for scale #6
0.7P refers to the gross weight for scale #7
0.8P refers to the gross weight for scale #8
Accessing Operating Parameters
Operating parameters may be accessed manually in two ways.
1. Key in the parameter number and press the [SELECT] key.
- Example: 0 [SELECT] selects the gross mode.
2. Enter the parameter in the “modes” list at setup parameters 300-309. Any parameter defined in the “modes” list is accessible by pressing [SELECT] in the normal operating mode to toggle through the defined selections.
Entering Parameter Values
Parameters that can be accessed manually may also be assigned values manually through the front key panel. All parameter values may be accessed and changed using macro assignments.
To manually enter a value, simply access the desired parameter as described above, key in the value and press [ENTER].
Fundamental Weight Parameters
Virtually all scales utilize the three basic weight parameters, GROSS, TARE and NET.
The GROSS weight can be defined as a measurement of the scale’s total live load.
The TARE weight represents a pre-established offset from a zero gross weight.
The NET weight is calculated as NET = GROSS – TARE.
As a practical example, consider a box of cereal. If you put a full box of cereal on a scale the GROSS weight is displayed showing the total weight of the box and its contents. If we want to know only the weight of the cereal inside the box, we can establish the weight of the box as a TARE weight. The scale automatically calculates the NET weight, or the weight of the cereal, by internally performing the calculation NET = GROSS – TARE.
