APA 6000 High Range Hardness Curves
Answer
The first bump usually seen in a APA 6000 High Range Hardness Analyzer curve is shown below the green arrow. This is caused by the influx of sample into the measuring cell. 

In the graph below you will notice a second bump down in the valley just above the orange arrow. This is due to the slug of clear titrant which is surrounded by colored sample. This is more prominent in samples with lower concentration where the valley is wider.
