4.3 Calculation of wallboard parameters and sample configurations
In this chapter the calculation formulas of the wallboard parameters (thresholds) are shown for the three categories Normal, Warning and Fail. Additionally you’ll find three sample configurations for orientation and quick setup.
*Example 1: Average threshold, average number of users
*Example 2: Low threshold, low number of users
*Example 3: High threshold, higher number of users
