These tests prove the influence of environmentel changes to the behavior of the weighing Process, aswell as the humidity influence on the weight of paper filters.
The RH Experiment was performed on a UMX5 Micro Balance using a 47 mm standard paperfilter used for diesel particulate matter testing. The paperfilter was left in the weighing-cell during the Experiment. Time taken 12 Hours.
This test shows the performance of the ECC-Chamber after changes in Temperature. The time it takes to return to normal operation, after a change has been made (max. about 2 hours after a change of 3°C). The charts are in 24 hours format.
This experiment shows the VWE-Analysis at IKT-Laboratory with operator induced perturbations and expains the results obtained.
