All you really need to do to see your measurements is login.

Once you're logged in, you'll be taken to the main page, which has a list of all of your different measurement points at the top.

If that's all a little too much (large companies can quickly have a lot of measurements), you can choose the individual customer and location you'd like to look at - this will reduce the clutter.

This can be done from the list at the bottom of the main page, or from the sidebar.
