Preparation
To calculate a value in percent, the reference percentage must be known.
This value can be entered into the weighing-in-percent program in one of three ways:
– The last reference percentage entered is loaded and displayed when you turn on the scale.
Place the corresponding weight on the scale and initialize the weighing-in-percent program;
– With automatic initialization switched on (see previous page), the scale goes into the
"weighing in percent" mode when you turn on the power and loads the last reference
percentage entered as well as the corresponding reference weight (Setup: Printout:
Application-defined output: Auto print upon initialization: All values);
– Enter the reference weight using the numeric keys and store it (

Equations
The following equations are used for the corresponding calculations:
Residue = Current weight ÷ 100% weight x 100%
Loss = (Current weight – 100% weight) ÷ 100% weight x 100%
Ratio1 = (100% weight – current weight) ÷ current weight x 100%
Ratio2 = 100% weight ÷ current weight x 100%
