The “Measurement Options” section of this manual
describes the uses of each method. Also see “Changing the

The Manual Sampling

Sample Rate Measurement Method
Sometimes conditions in an experiment change continu-
ously over time.
For example, the temperature in a beaker of water changes
as a Bunsen burner heats it. Traditionally, you would place
a glass thermometer into the beaker and observe and write
down the temperature every five seconds or so. Instead of
taking the measurements yourself, use Xplorer to automati-
cally take measurements at regular time intervals. This
automatic measurement is also called “Sampling.” The
number of seconds between measurements (or the number
of measurements taken in one second) is called a “Sample
Rate.” Xplorer can make measurements as slow as once
every 4 hours or as fast as 1000 times per second. Some
sensors require a sample rate to be no slower, or no faster
than a certain limit to make useful measurements. Xplorer
will not let you set a sample rate that is too fast or slow for
a specific sensor.
