Creating a New Calibration using a Single Point
This calibration method defines a new y-intercept, leaving the existing slope unchanged.
Adjusting a barometer to match the local barometric pressure is a good example of using
the Single Point calibration. The example below is using a force sensor connected to a
LabPro.
1. From the EasyData main screen, select Setup, and
then select CH1: (or the appropriate channel).
2. Select from the Sensor Setup screen.
3. Select . A menu is displayed showing the different
calibration methods.
4. Select Single Point Live….
5. Place your sensor into the necessary condition for the
calibration point (e.g. a force sensor with a known mass
hanging from it). Monitor the displayed Potential (V).
When the value is stable, select
.
6. Enter the known value for the calibration condition (e.g.
1.96 N for a 200 g mass), and select
.
