Gravitation Measurements: 5 November 2010 Swap screen casings

Referring to the graph:

The graph shows results of measurements taken from 9 to 10 November 2010.

Two sensors were placed in different screens, namely
      Brass (with a specific weight of 8.34)
      Iridium (with a specific weight of 22.7)

The experiment was run over several hours, changing the screens around periodically (see below). The Intermediate frequency is sampled every minute.

9.10.2010
Starting at 12h15, for 30 minute intervals, lift and replace the sensors 4 times without changing housing.
For 45 minute intervals, swap sensor housings 3 times, with last reading overnight

10.11.2010
New file starts at 07h57. Remove housings completely (sensors on wood base). Recording stopped at 12h15.

Below is a detailed view of the first few hours of the experiment.
